I know that an exhaust tip changes noise I got a 6 inch tip on mine and it changed the noise. I've been looking at putting a single stack in and was looking at getting a 6 or 7 inch stack. ANyone have experience with this sorta thing. I don't mind noise its not dd
That drone depends a lot on the muffling device, although anything bigger than 6" would be excessive loud. My 4" stack doesn't have any more cab noise than the tailpipe did, just lucked out on choosing the right muffler.
