I have a couple of buddies who have done it to their bikes and it sounds pretty darn good. IMO it is the most economical way to alter the sound of your exhaust. A few of them even took it a step further and added a second outlet on the other side making it even LOUDER!

That's the exact mod I did to mine and I love it! It is mucho louder, especially when you twist on it. Just know that you will lose torque below 3000rpm, but it becomes a monster above that.
The second outlet is coming on the next one that I do. Something simmilar to what Kevin did with the drummer by shortening the pipe. I don't have all the knowledge and engineering that went into what Kevin has pulled together, but it is a LOT of fun to experiment.

Dtx said it too...economical. That muffler mod cost less than $30 including paint and welding at the local muffler shop.

30 bucks is deffinitely worth some sound, but not the loss of bottom end....

Too true... I paid $388 to lose my bottom end with the Force pipe : ). It's like Vegas said... I do have more sitting in the middle now and that's good, but it wasn't worth the loss at the bottom I don't think...

That damn force pipe sounds SOO good though... I'm going to have to just cut it in half once I put my Drummer back on because I'm addicted to that visceral, snarly, crackely, LOUD sound... The Drummer is better for power though.

I tried to take the mod a step further and removed all 3 pipes in the middle also. Increased sound over stock, quieter than the Jardine, but a much nicer tone. But now I have a HUGE hole in the power band, 2500 to about 5k its a dog, but above 5k it pulls hard. Oops, I guess that is a failed idea. back to the drawing board.

Just wondering why the stock XB12 muffler is so bad. It's not loud, had a trick valve in it to give both low end torque and top end power, and it seems to be pretty durable too.

I wouldn't mind a little extra growl, but I rather enjoy showing people that Harley made engines don't have to be loud. Try covering up the exhaust outlet with your hand at idle. You can hear the engine running. It's a work of art!

I saw a web page once where they used a hole saw to cut a 1" diameter hole in the end of the muffler, then drilled or cut a hole in the internal pipe. Then welded a patch over the hole in the muffler body.

If I had a spare muffler I'd try it; shouldn't be as loud as cutting the pipe out completely.

Ack, probably just stick with the stock exhaust.

Same here. I've got no issues with it.

Whenever I can ride around everywhere at WOT and want the bike to go faster, I'll start bolting on engine mods. LOL! : )
