I have changed the powerplant from the original Flathead to a Small Block Ford 302. I am getting ready to take it to the exhaust shop. My question is I believe the 22" Smitty's may be a little too loud behind the 5.0 HO motor. So I need to choose another muffler. I run Flowmaster series 50 on my '34 Sedan and like the sound etc. Just looking for some input. Do you get a lot of drone from performance mufflers inside the cab like you can in a sedan ?
