Where are you people getting your information from? lol
I cant think of any of our applications that a 2.5" exhaust would be any better off than a 3". Maybe other than quietness but the difference is not much.
The performance aspect all motor or turbo is better 3" all the way.
Back in the days it used to be thought of as dont go any bigger than 2.5" as its not needed. Well those all turned out to be false. Even a full bolt on de will see a benifit from a 3" exhaust vs a 2.5".
I would be interested in one for a b13 minus the muffler as ill be using my own vibrant muffler.
