Hello, I'm new here and I have a BONE stock 08 STI I have about $600 to start with for now I want to get a catback exhaust I do like the COBB exhaust but I'm afraid it will be too quiet and I don't like how it tampers down to a 2.5 flange. I seen this exhaust on Amazon and I was wondering If anyone has one, heard of one, or found any info on it. From what I found its an M2 that all I can find. I can't find no video's or anything. Please Help I really like the looks of it but I'm afraid it will sound bad only because its $558 and I know sometimes you get what you pay for. If anyone has video's or any info on it let me know.

I don't understand one of the mid pipes on that system, why is it so curved, what is it supposed to be going around?.. there is no reason there needs to be that sort of bend on a cat back for our cars.

unless of course, poor design, or they are using a photo from a system for a different car.. ?

M2 eBay exhaust is garbage. If you want rust and insulation blow out in 1-2 years have at it.

M2 is a knock off company is operating off of the good name of another company of the same name that went out of business a decade ago that actually made a decent product.

Why does the 2.5" taper bother you? 2.5" is not a restriction. It supports much more power than you make now.

Brfatal is correct. A catback is just a noisemaker (an expensive one at that) as long as you're running the stock turbo. The gains will be minimal, unless you're one of those people where 3HP is "going to make a difference."

This.

Also keep in mind if you go full 3" you will need to purchase an adapter to go from your 2.5" downpipe to the 3" CBE.

I still don't understand the pipe above the muffler.

If your looking for something inexpensive check out the Tsudo, Invidia or Greddy single exits. There is another company which makes a decent quad exit for 5-600 bucks but their name is alluding me at the moment.

Pipe above the foreground muffler goes to the second muffler (it 180°s around the other side). The left set of tips should make a deeper exhaust note than the right set due to the extra length.

The midpipe with extra bends are to clear the Rear Diff.

okay thanks I never really seen anyone talk about the exhaust or seen videos so I though id ask and a I kind of figured for $558 for a quad it wouldn't be to great...Could someone direct me to a forum or know of a list from quietest to loudest exhaust? Maybe add some in between from what I already know? Looking for quad or double no single exits please.

01 Quietest - Stock
3 - SPT
4- Magnaflow
5- Q300
6- Cobb
7- Perrin
9- B&T Motorsports
10- Loudest - Crawford


Please let me know if this is correct so far, I'm looking for the loudest without a lot of drone at highway speeds? Crawford is way to loud, Perrin there is drone from what I hear the Cobb is good but not as loud as most exhaust so I'm undecided at this point.
