I got a bunch of metal roofing washers once welded them together with no holes lining up with adjacent holes. It made a very quite muffler . Part of my Idea was to let the original muffler act like an expansion chamber. I drilled holes in the washers large enough not to restrict flow. It was an experiment that did prove better than stock. Until I got a tuned pipe.

The washers were spaced about 1/4 inch apart there was a total of six washers if I remember right. While it worked better I sure had an oily bike though.

If you run the pipe without a baffle & without the end cap, it's gonna be helluva loud!!! (& probably get you pulled over!!!)

AFTER you set up the pipe how it will be permanently, you will have to re-jet the carb.

Hey Guys! I know this sound stupid but, how do you remove
the bottom of the muffler? I tried unscrewing the two screws on the
bottom and it still wouldn't come out? And after I take it out then what should
I do to make it go faster? I've done the break-in period (1 Gallon) but I'm sure
I have not gone 200 miles yet and it only makes it up to 27mph on flat.
How do I make it go faster without making it a ton louder?

Andrew
