| Has anyone with this or a similar GM car with a 3.4 L V6 and a single

Frankly, if I had a GP, I wouldn't want to draw any added undue attention to
myself by making the car overly noisy to boot. Had a 1967 GTO with Thrush
glass packs a few decades back...the monotone rumble when cruising at
highway speeds with that 4-11 rear in it about drove me crazy! Plus I got
stopped a LOT more by the cops after I put the Thrushes on it.
I think most states have some hefty fines if you remove the catalytic
converter, if they find out about it.
I'd highly recommend leaving your exhaust system stock...just my opinion.
