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..

You can get baffles like rossmick said and also make one. Lots of folks here have doen it with some pipe and baffle packing.

Alsonis there a brand on the pipe? May be a ready made baffle the PO may have tossed you can buy.

Also if that is a 2” / 51mm outlet then there are a lot of aftermarket slip on silencers you could add.

I have a MAC muffler that might fit. It should be pretty quiet and it has never been on a bike. What is the OD of that pipe?

I’m actually looking for a MAC muffler for my 550, got any pics?

usually a name would be stamped or a plate on the side near the outlet or maybe on one of the header pipes.

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
