Neither, leave the stock muffler and drive a sharpened steel rod the size of the rear hole all the way thru it. It will go thru the perforated plate and then thru a solid one, it will stop the hissing sound that comes from too much back pressure. I took the white spacer out from under the main jet at the same time as it will need more fuel now that it is getting rid of the exhaust, and too hell with Kyoto, do your part for global warming. I left the idle lean as most emmision come from idling engines,,,and I like the backfiring coming up to a stop sign, shakes the carbon off the valves and piston tops.
I have a friend who made a muffler for his harley by slipping a piece of pipe inside his straight pipe. The inside sleeve had a bunch of indentations pounded into it so the holes were facing the exhaust. At "normal" power settings it is surprisingly mellow, at power it shakes the insulators off the power poles and the deer and the antelope can hear him coming from a mile. Cheap and easy, and it looked like he had straight pipes.
