C4 Corvette with Billy Boat exhaust

[VetteAholicZ06]

It's a lot deeper in tone.

not enough of a change in sound for the price.

3" pipe.

2.5" or 3" pipe?

[mikegldn]

Not too bad. In 6th gear under 70mph or so it's a bit loud but either downshifting to 5th or speeding up to 75 or so takes care of it. I think with long tube headers it'd be pretty loud - I still have the cast iron manifolds.

Very nice. How is it with cabin resonation at hwy speeds?

[99custom]

Ehh..Not what I expected
