I doubt it. To be honest, I keep wondering why every company keeps putting out the same 2.5" exhaust. It's almost as if people are afraid of 3" exhausts.

In the civic community (8thcivic), everyone ran 2.25-2.5" exhausts for years because of these claims that a 3" was 'too big'. Finally a company came out with a 3" and showed that it gained everywhere, with no losses, and now no one wants an exhaust that isn't a 3". I suspect the gains would be just as great (greater) here. I really don't get all of the FI guys who are running 2.5" DPs/exhausts. That one really boggles my mind.
