Im thinking about going catless. Have a few questions, and would appreciate any feedback;

1st, will a Turboxs race pipe from a WRX, work with my rfl, have a seller over on Nasioc....

What do you catless guys think, is it worth it, or just a headache when getting her inspected? I recently had the privelage to drive Avatar's catless STi, and was really impressed with the throttle responce!

What about a exhaust dump pipe...Are they any options with that route, with the RFL, or would it take custom work?

With all that boost from the SZ55, I really think that last cat is holding back..

(SZ55, ARC fmic, AEM Shorty, Utec, Perrin 186, Walb 255, and supporting mods....)

I am in the middle of upgrading to a SZ55. I was catless though with my stage 2 setup and it really does make a good difference over a catted TBE. Me and my friend have same cars with same mods at the time (TBE and intake) i was catless and he had a cat and i would consistantly pull a car to a car and a half on him. I'm sure with the SZ55 that much air going through will make even a greater difference.
How do you like your SZ55 set-up though?? How is the top-end compared to stage 2?? I have heard that 6th gear feels like 4th. Is this true??

If you pay the money for a quality catalytic converter that is metal substrate, the flow should not hurt your power by too much at all. If you purchase a less flowing ceramic cat, like TXS's then you will start to impede the flow more and more.

Just swap it out when it`s time for emissions/inspection
I <3 my catless.

The Pulls are ridiculous! She pulls all the way to my rev limited 7k, which I'm sure would keep going past that.

The gears are a lot longer so in a sence they do feel like higher gears. 1st is still ridiculously fast. Its alot of fun, little more laggy but nothing to cry about.

I took some guys out for a ride in the other day SPAZEGUN, and ZABUZA they seemed to enjoy it.

Can I get metal substrate to work with my rfl? If so which one where at ect....

-I'm leaning more and more to catless. Is this a pretty simple swap out, I'm assuming its a few bolts like the rest of the ehaust.

-In reffrence to my other Q, I have someone with a wrx catless portion from a turbosx, will it work with my STi''s rfl? Or is it just worth it to buy new?

Thanks guys, really appreciate the feedback!

Check out SMC. They are the original designer (Austrailian I think) of the TXS products and they offer the 4" dp with a ss cat. I believe it was Ese that found their resonated mid-pipe so you might check his journal for some links. The SMC ss catted dp is super nice but costs like $700ish if I recall.

They offer a metal substrate cat that should bolt between your TXS downpipe and TXS mid-pipe. You should not need to replace the entire DP.

pig, dude, your car rocks.

And yes go catless!!! there are plenty of places that will hook you up come emissions time. I'm catless, and I'm not worried!

one thing though is your exhaust will get louder!!!

oh and if that wrx guy has a full 3" it should fit. Call turboxs, they should be able to give you info on it.

Thanks Spaze! I'm in the process of talking with http://WorldOnePerformamce.com


I think the concensus is Catless, the SMC kit sounds nice but, a little too much with all my past expenses...(forgot to mention I have their Alky kit too)

Once again guys, great info Thanks!

I just went catless today with my TurboXS TBE and all I can say is WHOA! I never thought that the cat was THAT restrictive, as I was looking into it, I didn't think it would effect the exhaust flow as much as it did. I was impressed, thought I would be able to tell at all, but boy was I wrong. Two thumbs up for going catless do it!

Arms been twisted enough fellas, Race pipe ORDERED!

One more mod to explain to the wife. Ahhh SHHHHHH*T! Hope one of you guys has a coozy couch ready for me


Thanks for Something....

I just got my TXS catless TBE-Ti today. I can't stop looking at it. I'm glad I went catless, just waiting on the AP so I can slap them on. Only concern is boost creep for me, but with your snail, I'm sure catless would be all improvement for you.

Thats good to hear. Yeah the only thing i was really concerned about was spool, but after reading about a couple people who got the fat-boy upgrade they said it actually spooled faster than a SZ49. I talked to Jerry at Deadbolt and he told me that the SZ49 with fat-boy only outspools the 55 with fat-boy by about 100-200 rpm, but the SZ55 would have a higher top-end. After i heard this i was sold.
