Hey, I have an opel gt with a performance but streetable cam, large valves, large pistons, good compression, and a weber downdraft. It chops at an idle and comes on very strong at around 2.5 or 3000 rpm. Does anyone have a suggestion on a good universal muffler? I already know what tips I want to use, but i'd like to see what people recommend that sounds pretty good on a performance opel.
