dynomax in 4"?
i really like how dynomax mufflers sound, but when I put my new motor in I want to go with a 4" intermediate pipe, but i cant find a 4" crossflow muffler with dual exits besides spintech. I want to go with a dynomax superturbo cause of how quiet they are. Is it possible to modify a 3" muffler to accept a 4" pipe?
