Now, I've been researching different exhaust setups for my bone stock IX, and I had it narrowed down to a TurboXS turboback system, until I saw that it was a little slanted. Here's my problem: I live in California and the exhaust can't be too loud, and I don't want a slanted exhaust setup. I also am not planning on getting a JDM rear bumper anytime soon if that matters. Any suggestions?

 

I just went through the process of choosing an exhaust. What I did was i came up with a set of standards I wanted in an exhaust.

I came up with wanting an exhaust that:

1. is full 3 inches (no taper)
2. has o2 bung (i have an evo 8)
3. no resonator
4. uses stock hangers


I ended up getting a Turbo XS cat-back. It has a resonator but I decided I can live with that. Unfortunately the mid-pipe they sent me was for an Evo X not an Evo 8 so I haven't installed it yet.

 

I agree with your 1 and 4. Don't think 2 applies to me, but if I'm wrong please correct me . Also, I probably wouldn't mind sticking to a cat-back if that's what it takes, mainly because of the emissions and the cops in CA lol

 

Yeah the JDM rear bumper does matter. I got the greddy Ti-C exhaust for my evo and on the oem rear bumper it was about .25 inches behind the rear bumper's exhaust outlet. When I got my jdm rear bumper, the exhaust stuck out 2-3 inches.

 

So with the Greddy Ti-C, would you say that it looked pretty close to stock in terms of placement? I've only heard a few clips of the catback on YouTube and it seemed pretty loud haha

 

Your o2 bung will be on the cat since you have an Evo IX. I think you'll be able to get a full turbo back you'll just want to make sure you get a hi-flow cat not a test pipe. You should try to find out what other Evo owners in CA have done.

Have you looked at the Exhaust Thread?

 

I believe the Greddy Ti-C is the catback and it tapers down to 2.5 to meet the cat.

The Greddy Competition Ti-C is the full turbo-back and it is full 3 inches the whole way. However I believe this exhaust has a longer downpipe and there is no space for a cat.

 

Yeah, I searched out a couple brands and maybe I'm just really picky or they weren't the greatest pics/videos, but I kept finding something I didn't like about them. That's why I made this topic, because there's no doubt you guys know a ton more about Evo exhausts than I do so why not make use of a good resource? Plus, I was searching for over an hour just now

 

Yea I took 2 months to finally make my decision only to find out they don't make it anymore. So i went with my 2nd choice.

 

Jim, sent you a PM.

 

Hmm, was just looking at the Greddy catback, and I do like the sound and look. Its not slanted and it doesn't seem overly loud, but that would probably change if I got a downpipe and possibly a test pipe lol

 

i have the works turboback, w/cat instead of test pipe. good craftsmanship and quiet. even at high rpms. there are better out there.

 

Yeah, I'm probably gonna keep the stock cat on there regardless of what setup I choose because my Evo is my daily. Don't need to be pulled over/harassed all the time lol

 

I have the mil.spec 100 cell cat, and it's not any louder than stock as far as I can tell. as for the exhaust, if you're worried about it fitting with the JDM rear, order the JDM version of the exhaust. that's what I should have done when I got my HKS carbon TI. I just recently had 2.5" cut from the piping to fit it to the JDM rear.

 

I really give it to you cali guys, all the eco spec **** you have to go through!!! man my car would be impounded after the first month....the epa limits the ***** out of you. good luck with your choice.
