Neil,

I picked up two 3 foot lengths of the perf tube about 13-14 years ago at a metal scrap yard. Yup, I have been procrastinating about making a muffler for that long. The 6" tubing for the can I got last fall at another scrap yard. The 2" tubing were off cuts from a steam line install in a lab I worked in.... it all adds up.

The stock wbx muffler is a baffle type unit, I think. I wasn't certain that a flow through with packing, like I made, would be quiet enough, but it is. Probably the heavy guage components helps absorb some of the sound/vibrations.
