Anyone have it on a rally 2003 to be specific?. Ant difference on performance/ sound?.

 

There are people that have this on their car. Check the registry of cars and run a search in there. You are bound to find several comments on the subject. It makes it considerably louder from what I hear.

I have it on my car.. I noticed a slight difference in acceleration. Every bit counts. I notice it especially in the upper RPMs. If you do a little search I also have a thread with sound clips of it.

 

I have this mod and it definatly affects higher rpm; like interstate speeds and top speed. I was able to accelerate from 80-110+ quite a bit faster with this mod; only thing is it makes exhaust stink a bit more and is a whole lot louder; i already have headers and catback; dont like it much louder than that.
