Thanks

Do you know off hand if there are any independent before and after dynos that show gains of CBE after a test pipe?

I'm starting to think that whatever the first exhaust mod done is, that ends up being the the one that picks up 10 -15 whp (with test pipes being the least expensive for that gain) and everything else just adds another 3-7 here and there.

I can't believe that the stillen or FI exhausts are all that different in design. There's only so many ways to massage a N/A motor with exhaust tubing

However, this does leave me wondering further about seeing the difference between X, H, and Y pipes.

I'd say the two major improvements in the Nismo S-tune design are the better flowing Y and the straighter flowing tail pipes out the single mufler.

Has anyone switched between any of these and done comparison dynos?
