Yes,the stock muffler is only 12 pounds, BUT, it impacts acceleration every bit as much as if it weighed 27.5 pounds ( Yes, I ran the tests, it was complicated & time consuming, but, I did it).

Face it, ugly simply weighs things down. & the stock muffler is UGG LEE.

Sorry, I have to agree with Justin, that thing is ugly. I think the sportster muffler looks best of all replacements. Just my opinion

Start takin weight off the bottom, and you start raisin the COG,....and for ya know it, you end up w/ a Harley ! A thing of beauty ?? It ain't been changed one bit in 30 years ! There is a reason,.....maybe because if the beauty can't be improved, it won't be ??

The lightest weight is a straight pipe. Chrome it, and some even say it is beautiful.

Straight pipes, though, are dumb. They hurt performance (really hard to tune) and they are so loud they are unsafe and they P O the public. We don't need any more folks P O'd at us.

The point? I knew a guy I worked with at Robins AFB who needed something to serve as a muffler, but he had no money to buy one for his SR500. He did have a 2.5' length of exhaust pipe, though, that he clamped on to the existing header.

He brazed a washer just inside the end of that pipe. The pipe was maybe 1 1/4" diameter and the washer had maybe a 3/8" hole in it. Needless to say, the "muffler" was quiet but the thing ran like s**t. It made about 10 hp and wouldn't rev over maybe 2500 rpm.

So, he started drilling 1/4" holes in the bottom of the pipe (so you couldn't see the holes), starting near the end of the pipe with the washer in it. Drill a hole, go for a ride. Drill a hole, go for another ride. He did this many times. He got it up to maybe 15 or 20 holes, and quit there, claiming it felt stock, sounded a little louder than stock, and costed him zilch.

I heard the bike a few times, and it wasn't very loud. The noise it made was hard to describe. Not raucous, not flat and tinny, but yet not sounding like a long pipe. It was just sort of there.

And,.. it was very light weight, and very cheap.

Diamond Jim wound up with a very similar system on Black Beauty, a line of holes drilled in the bottom of the pipe.

Watching Lancer ride down a dirt road was fun, the pipe blew up dust off the road when it down-puffed through the holes.

=====================

Folks have spent a lot of money on exhaust systems, but the hurley take off muffler seems to be the best fit up of light, inexpensive and performance.

It always seemed to me the Supertrapp was not much more than a can with an adjustable circumferential "hole" near the end of it. Not much diff than the nearly free muffler described above.

Stole this from another site...

1. drill hole at end of straight pipe
2. tack weld a 1" washer to flathead bolt; should look like a lolipop
3. slip through drilled hole, and thread with a nut....
5. twist for adjustable back pressure... cinch when it runs sufficient...

You could drill the washer for a different diameter hole or drill more holes and use more washers. Seems to me, the supertrap is just a glorified version of this method.
