Back on page 1, JCC mentioned using SS exhaust pipe. I'm assuming he meant stainless steel exhaust pipe. Can someone explain why that is quieter?


I suspect most any form of insulation will reduce noise and heat in a car. A few decades back, I knew a guy who built an early 1970's Dodge custom van. He used fiberglass insulation that is typically used in building homes in the walls of the van. On the floor he had carpet with some kind of thick padding under it. He used some kind of performance mufflers that were fairly quiet, but the van definitely had a little rumble to it. (He had modified the 360.) I do not know all the details, but that van was surprisingly quiet inside and it would RUN!!
