I can tell you that with drag pipes they don't make much difference sound wise. Some but not very much. The effect will probably be more with a longer pipe though, let me know what your results are.



Dog, I got 'em installed this evening, but I did it a little differently than originally planned. As it turns out, the large end of the 4" baffles is a good fit inside the first part of the reducer cone if you install them "backwards." The baffle will slide in about 3/4" before it hits the necked-down area. Of course, once it's in there, you can't install the nut and bolt. I solved that problem by asking a friend to weld the nuts into the baffles. Then I just had to drill a hole through the pipes for the baffle bolt and install the bolt from the outside. The small perforated end of the baffles sticks out of the pipes into the headers about 2-1/2", but that doesn't cause any problems.

The sound is pretty much what I expected. I had a pair of homemade baffles in there for a few days, and they produced a similar effect. Unfortunately, the homemade versions fell apart 'cause I forgot that exhaust gas is hot enough to melt solder. Doh! Anyway, without the baffles, the pipes are pretty obvious as being open. At idle, they have the watery echo that's characteristic of open pipes. The baffles remove that sound and they also quiet the pipes, but just a little. The idle is nice and throaty (same for decel, with very little popping), and the upper RPMs at highway speeds don't produce that high-pitched wail like the TORS. Acceleration through the gears is a blast. The bike is still very loud, but it's gone from "Danm I've got a headache.. can ya hear me... what???" to "Hey, is that a cop?" Seriously, I like the sound a lot, but these might still be loud enough to get a ticket. I'll just need to ride awhile and see what happens. Tough job, but someone's gotta do it.
