I was out looking at the exhaust on my stock '97 last night. That
Y-pipe
is tiny! Has anyone replaced it with some 2-1/4", maybe 2-1/2" pipe
into the cat?
I'm sure some exhaust shops could easily fabricate this pipe, and I'd
be willing to be it would increase power. In fact, the Y-pipe seems
to be the biggest bottleneck.
