Hey all, I want to quiet these down a bit....they sound good but I dont like drawing attention. They are 4into1 pipe...nothing in there at all. Is there a good read on quieting exhaust, or anyone got any thought on what I could do? Thanks..
2.5" is way large and it's probably a copy of the Yoshimura design/style so there should be a baffle inside that secondary pipe. It's much larger than most mufflers or secondary pipes. I'd guess it was a pipe from Carpy but I have no idea who made them for him.. I think he had a couple of different manufacturers in the past.
I checked his website and I didn't see a straight tailpipe but did find a baffle
