There's a subsidiary of Flowmaster named Hushpower, which produces a quieter sidepipe muffler. I had a set installed on my Kirkham, eschewing the stock Kirkham sidepipe muffler.

I mostly wanted a car that I could take to the track that wouldn't be red flagged for noise level. It's much quieter than my old Corvette with sidepipes.
