Exhaust schooling....

[cbrianroll]

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 exhaust baffles on eBay

I have no idea what they are like though

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.

Thanks, I dont see a name on them....they are painted pretty heavy though...

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?

2.5 inches...where would a name stamp be?

 

[Maritime]

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

I was hoping it wasnt under the wrap....hate to pull it off and find something else wrong lol.

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
