I am currently running a full turboback from AMS and I just got a Greddy EVO catback at a good price so I picked it up. I want to throw it on to see if it sounds any better to me as well as drive well. I always liked Greddy EVO's on previous cars but once I got this I noticed that the front flange has a bit of restriction (about 2.5") where it meets the DP. Has there ever been any sort of exhaust shootout/comparison on here or anywhere? I am looking for all specs like weight, db at idle/driving, and power gains for all exhausts. Usually HKS and Greddy were the top contenders in previous cars I've had.

 

the most proven exhausts for these cars would probably be buschur racing's exhaust systems

ams would not be too far behind

you wouldn't be helping yourself by switching

 

all the known exhausts are good, buschur, ams, hks, greddy. But it depends how loud you want it.

 

does buschur exhaust really out perform the others, i know this the case with the head and bottom half builds

 

I'm thinking about just keeping the AMS but I was thinking about getting a new one. I don't think I'd gain much. I just picked up a Greddy catback but I'm gonna end up selling it. I never even put it on. I think if I change it's gonna be full titanium.

Too bad there isn't an exhaust shootout performed by a bored dyno shop or something. That would be helpful. My last car was a subaru and they had an exhaust shootout in a magazine that worked out well. They said all specs of each exhaust on the same car. Awesome for shoppers. Just my $.02
