who is running flowmaster cat back

[jamieszr1]

hi i have a 1991 zr1 and i am running with flowmaster cat back and was wondering what fellow members think of this exhaust

That's what I have on my 91. It wouldn't have been my first choice but was on the car when I got it. It's surprisingly quiet for a Flowmaster setup. The system itself looks fairly impressive, nice large pipe, nice smooth bends. In my opinion it's a bit too quiet but might be just about right with the addition of long-tube headers and losing the cats

Exactly :!:

I know of one ZR-1 with headers straight to their Flowmaster exhaust, and it is plenty loud.
