I'm going to have a shop redo the exhaust on my 53 Chevy since I suspect a leak causing my cab to smell. It has a SBC 350 with an RV cam, ram head manifolds, and 1.5" pipe going to the back. It sounds too "put put put put" at idle... Here is a clip to how it currently sounds: Below is the exact sound I want to a "T". The 66 c-10 has a 283 with 2" pipes to the bumper and brockman mellowtone glasspacks (but not sure what length, this was owned by a HAMB member named Shad). I bought 22" brockman mellowtones and was thinking of replacing my pipes with 2" diameter pipes to the bumper. Am I likely to get a similar sound? I'm most annoyed with how mine sounds at idle and want to get rid of that "put put put" sound. Is this because my 350 has an RV cam? I already adjusted the idle to be a little higher but it still has that lopey sound I'm not too fond of at idle. The 66 C-10 doesn't sound annoying to me at idle. Thanks.
