Ok, so I ended up buying the Milltek Catback from LiC Motorsports. Was a pleasure dealing with them and the price wasn't "as horrendous" as elsewhere. Including shipping I probably saved over $400 versus local options. Sold my Corsa to offset some of the cost.

Mind you I'm still suffering from an injured shoulder from doing the install... my chest does NOT fit under the car near the downpipe even when the rear wheels are up on ramps so I had to hyper extend my arms to take the bolts off and put them and the new gasket back on. I recommend a friend so you don't have to hold things up with one hand and torque things with the other.

The Milltek is very high quality overall. It is visually appealing and appears to be constructed well. Cold starts are back to stock volume levels - SIGNIFICANTLY below the volume of both the SPT and the Corsa (My car doesn't rattle windows in the house any more). While cruising, it sounds nice but with subdued volume. It has absolutely zero drone across the entire RPM range.

Apparently I have an EWG as well... I wasn't aware that I did when I had the Corsa on... the Corsa sort of drowned that out. I actually /like/ my EWG now. That's only loud when I really intentionally step on it... and my EWG at 21 PSI is quieter than me attempting to pull up the hill at the end of my street at 25 mph at 6 in the morning with the Corsa on... The local constabulary have now deemed me beneath their notice one again.

If you are looking for an exhaust for your sleeper or family car or you're looking to tame in the volume, I'd highly recommend the Milltek. If you want to hear one in person and you're near Central NJ, I'll be more than glad to meet up.
Wait 500-1000 miles for the Milltek to full break in, when I first got it I thought it was a little too quiet and tame but it has grown not necessarily louder, but more aggressive sounding.

Most people think that a louder exhaust is automatically more sporty or aggressive, and I guess the Subaru crowd has a huge tolerance for loudness as evidenced by the very positive reception of the Corsa exhaust. Sheesh, if drowning out an EWG which is one of the loudest exhaust mods you could possibly make to your car is not a sign of a really loud exhaust, I don't know what is!

But at any rate at a recent autocross there were a few Subarus with different exhausts, including a Perrin, the normal Invidia, Nameless etc. Surprisingly you are seeing more and more ELH cars as well. At any rate all of these cars were a lot louder than the Milltek by a significant margin, yet the Milltek to both me and another experienced Subaru modder and driving instructor was a lot more aggressive.

Yes opinions are like assholes, everybody's got one etc etc etc. People think, just like wine "if I like it then it must be good", but there is an objective way to evaluate things that you may like or dislike. In wine for example you take the complexity of the flavor, how harmonious it is, and above all how complex and long the finish lasts. This last element is probably the most accurate at guiding quality and deciding price. And taking it from an objective point of view, most of these other Subaru exhausts like the Corsa make it seem more fun by cranking it up to 11. But they are not harmonious. It's like hearing a lot of musical instruments all playing at the same time, or in a room full of people shouting, sure, there's your tonality. You hear every pitch of possible sound booming at you at 11/10. Fun for some but cacophonic over harmonious. If you drive long enough in the car, you will damage your hearing and I can confirm this because the Corsa made my ears ring, not to mention the already discussed windows vibraing, 100+dB starts, angry wife, waking up your children, pissed off neighbors, noise violations, failing inspection etc etc etc.

The Milltek takes a different approach, it is very thoroughly engineered to hold up to any mod set from mild to wild, yet provide a harmonious and exotic sound. Rather than just blanket screaming and turning up the volume and the distortion to 11 on everything, it really is very musical, refined sounding, more like a German type car. So it relies on refinement, not just reducing packing (which is also a cheap way to save money by the builder).

Sadly it is expensive, but you get what you pay for. The real tragedy is that the Corsa whose workmanship is far less refined, doesn't fit that well together costs the same.

List price for both these exhausts is north of 1000 dollars, but the difference is they sell lots of Corsas (and Perrins and Invidias and Nameless and Greddy and Cobb though the latter isn't bad). Each Milltek is more or less made to order and you have to pay for the shipping of the individual unit instead of a whole container's worth coming over. But when you compare list price to list price, the Milltek is just so much more substanital, thicker, well put together than at least the Corsa (which felt cheap and tinny) or any other exhaust in this price range. But it doesn't sell enough to get any cheaper than list price which is too bad, because even at "list price" it represents a wonderful value considering the workmanship and refinement.

Good read fellas... if only all over threads carried this much insightfulness.

I think I may switch over to this. I will have ELH and a catless invidia DP to mate with it.

Hey, you can come and hear it again at ADSI! I just got back but it was disappointing for mebecause my MPSS are worn to bits. I see signs of ground scraping more than 1/2 way down the sidewall. I have been using Hoosiers at autocross and track days in warmer weather but they are absolutely worn to the bone. I got 1:31 on the "old course" at ADSI today and despite better coilovers this year last year I got 1:25 but it felt like I was driving on putrid squish. Attribute that somewhat to the cold day because everyone's tires were not hooking up and mostly to my moribund tires.

I think the next ADSI will be a 1/2 day event, we are asking Anthony to do it maybe Nov 8th or Nov 15th.

Always happy to see Subaru owners show up to events like this to drive their cars in anger, the way they should be, safely in a secure environment. And for a car like yours, you can get to real redline 3rd gear speeds, that's all I'm saying, because this isn't your grandfather's parking lot autocross, you get a 1+ mile track of empty, curvey runway.

Objectively speaking I didn't think your car sounded bad, but the Milltek is more complex & aggressive while being quieter as well. Unless you overcook a slalom on the "instructional" part of ADSI causing one of those malignant spinouts. That happens when you exceed the limits of your car, then the tire squeal (and smoke!) kind of overwhelms everything. SCREEEEECH (and cough cough from tire smoke if your windows are down). It's scary for a second, feels like your car will never stop but if you put "two feet in" you will be fine. Then you learn not to ever exceed that threshold ever again, on public roads or otherwise, but you will know.

Come again, there's lots to learn!

I'll definitely come again!! Every time there was a day on the calendar i'd have something else to do and couldn't make it. Then my Volks came in and RPF1s came off with the ZIIs which turned out to be junk. So i have a set of RPF1s which need new rubber that i haven't done anything about yet and to your point, there is no way i'm going to run the Volks with MPSSs with them being so new. A season or two down the line then different story.

I'd also prefer not to be DDing the car and/or have a way to trailer the car there. That puncture and the ensuing scramble to figure out a way to get it plugged definitely opened by eyes on how best to be prepared. I also developed some spring binding on my T2s at ADSI that i want to better address and have a few other suspension changes i want to make in the spring.

Looking forward to hitting up the big track though! I never got a run on it after the puncture...

I recently picked up a used Milltek cat-back, which nicely matches the Milltek downpipe that my local shop had lying around and fitted to my 08 STI a couple of years ago. I totally agree that the Milltek is a more refined sound than the stock with absolutely no rasp or drone, just a soft burble. It has a deeper/slightly louder exhaust note at idle, but is nice and quiet when the engine is under load.

The only downside over some of the other choices is that you hear more rattles, transmission noise.

The upside is that you can really hear stock BPV and turbo noises :D :tup:

I've uploaded a couple of videos of dyno runs yesterday, one that was dialing out the 2800 rpm GR stutter (using a IAP anti-stutter kit and adjusted comp. tables), and the other was a full redline run. In both you can hear that the (nice quiet) dyno is making most of the noise.

Thanks Toivonen, when the exhaust popped up on Craigslist your review and Youtube video really helped in the decision to buy. I'm really happy with the Milltek!

You're welcome! It's a neat whose most unique feature is that it allows a very aggressive sound at a modest volume level. The other distinguishing feature of this exhaust is it's the only catback I've ever heard or even seen videos on the GR chassis that still preserves a bit of a rumble and deep sound; all the other catbacks when you go ELH have a raspy higher pitched "buzzing".

How does the Milltek CBE compare to the new Cobb CBE as quietness if I don't mine not have a 3 inch CBE.

I have a rotated turbo Inv Race El header and Cattless down pipe . I just want stock like quiet maybe a little louder no drone with out spending too much $$$$ on the Milltek. Would the Cobb do the trick

I have a sedan

You'll have to ask this around. The only Cobb cars I have heard in person were with ULH and they were kind of loud but sounded really neat. I like the Cobb.

However Cobb seems to be a bit noisier and have more drone, also be higher pitched when going ELH.

I'm very noise sensitive and I love my Milltek both in how aggressive it sounds and how reasonable the noise level it. Cobb is somewhat more but it depends on your mods. A lightly modded car might do fine with it, as the mods increase I've gotten PM's from people who used to like their Cobb but now grew tired of how loud it is.

IMHO the "quietest" catback award belongs to the Milltek. That said it seems to work better with time. All the part throttle loudness and "not quite loud enough" issues both seem to have smoothed out with time. Like a fine wine it needs time to age or break in.

Looking back if you have a VF48 on your car and a stock CBE an upgrade does nothing but noise. The bigger the turbo the more 3" flow helps.

My Q300 with catless DP and ELH is loud and I am growing tired of it. Reading this seems like the Miltek is the quietest option for us ELH guys with no cats. Just wish there were more vids of sound clips :-(

PM MazNJ, he seems happy with his. I live in Southern New England, if you want to go for a ride one of these days PM me.

Here's another video:

https://www.youtube.com/watch?v=SpU1s-aJAGwer vid:


It's tough to say that you will love the exhaust because I bought the exhaust on a recommendation of a well known forum member who raves about his and I found it intolerably, ear splittingly, blow your house down loud. However, I will provide you with some general facts you will find useful:

1. everything upstream of the cat back as well as higher power levels can change sound quality as well as keep making it louder and louder.
2.once the downpipe gets changed it gets kind of loud, anything else like headers, turbo or CBE and the car will pretty much be pretty loud no matter what.
3. stock CBE is quietest with one exception
4. according to sound readings Milltek can be expected to be
-from inside even a highly modified car more than yours slightly louder than a 100% stock in most conditions but about as loud from inside the car at WOT.
5. Milltek is the only CBE I have heard with ELH that has some bassiness to it and doesn't buzz nor rasp
6. I haven't heard them all but I have heard SPT, Corsa, Invidia Race and Q300, Cobb, Perrin, Borla, Tanabe (can't remember which one), Tomei Expreme, CBE delete, straight pipe that I can think of and Milltek is both the quietest from inside regardless of mod level yet the most aggressive as well as deep sounding with ELH on.

It's a good exhaust for the noise sensitive because it does not use loudness as a means to sound more aggressive but rather tone though with your mods it will be IMHO plenty loud enough.

Other than going back to stock there really are no other options for this level of quietness.

Thx for the info, much appreciated.

Would going back to a catted DP help me lower the noise even more? I know i will loose some power :(

It would quiet things down slightly but reduce the drone and rasp somewhat. It is a less expensive, albeit less effective alternative than buying a new CBE. You would probably need a retune as well which should factor into your cost analysis. I would say try it but buy used, catted DP's are a few hundred bucks.

I have a catted DP and even then with the Corsa which is more or less about as loud as the Invidia, in some ways quieter at cruise, in some ways louder at WOT, maybe mating less well with ELH, and I found it absolutely intolerable under almost all conditions save steady <65mph cruise. It makes a difference but not a big one, I don't think enough to make an exhaust you find grating into one you find tolerable.

Why don't you post on the regional forums here and NASIOC about someone with catted DP and ELH with the Q300 for a ride and see how it goes?

Where do you live, if you're anywhere near Southern New England I would be happy to take you for a ride.

I am in North Carolina but was living in Long Island up until this July.

Catted DP: I meant matching up a Milltek Catback with a Catted DP vs my catless DP - would that help in making it even quieter? I gave up on my catback already and will not waste time, $ and a tune just to see if it will sound better with a catted DP.

I am looking at the Milltek but now thinking that i may also want to do a catted DP to go with it to make even quieter. I am not changing my ELH.

Thx for the offer! but I am in NC :(

Yes switching to a catted DP plus changing to the Milltek will make your setup a lot quieter. The catted part will not add a whole lot more but tends to make a slight difference with the most unpleasant parts of grating noise: drone and rasp. You may lose a tad of throttle response (though not much), and they say a slight bit of power, it's been written to be about 5whp. I don't think you will notice a lot of loss in the power department. Car might be less likely to boost creep in cold weather as well. I would have it retuned just in case; if you're doing the work yourself stay out of boost until you can get it tuned.

I am very sure you will like the Milltek better than the Q300 not just because it's very easy on the ears but because it's a very aggressive, tuned sounding exhaust that preserves something reminiscent of factory like noise level that's not totally antisocial even in a modded car.

I am so glad that I found this thread...and your detail descriptions of each Catback system helps a lot. You described in your 3rd post that the stock & Milltek are more or less equivalent and that Cobb/SPT would be slightly louder but not as loud as Q300. Where would you put the Borla CBE #14032 on your scale ? Is Borla louder/quieter that Q300 ?

I too am favoring hi-flow with stock like sound volume but I just can't stomach the Milltek price....I was going down the Tanabe Medallion Touring (max. 93dB) route until I saw this thread....then I saw a few Borla reviews here and thought it might be possible. Really appreciate your help. Thanks

:rofl:

Actually with the Killer B header the Corsa is very tinny and farty whereas the Milltek is more deep and bassy, it's the opposite....

As always love the friendship, camraderie, sense of humour and that you're still around!

Reading thru this thread and came across this. Killer B with corsa is qhat I plan on doing. Question I have is how do you know this set up is tinny and farty. All the corsa s I have heard have been deep and throaty. But they were all with ulh's. Haven't heard one with ELH.

Actually just found one one YouTube. Completely non tinny and non farty. Will link video

I ran a Corsa, SPT, and Milltek. Ran the Corsa before and after building the block and adding a Spoolinator and going catless. Ran SPT stock and with just Killer B headers.

The SPT after replacing the headers had excessive drone but loved it stock.

The Corsa after going up turbo just become too pronounced for me with 105 db startups the knocked plates off shelves and rattled every window in the house. It also had a odd excess noise in the normal cruising rev range, something like 2800 to 3500 which sounded like you were flooring it despite cruising. Went to the Milltek and have 85 db startups, a nice, deep sound, and no aural oddness.
