Has anyone tried to further silence their IDS2? I am running six discs, and found the pipe too loud, too much of a "hollow" sound that seems to echo in my helmet, and carried a great distance in the woods (which is really undesireable). I tried 4 discs, but that didn't much reduce the sound while cutting off anything over 3/4 throttle. I went back to 6 discs, which works great with the stock jetting and the mixture screw open to 1 1/4 turns. Tonight I tried stuffing the empty chamber after the discs with rolled-up "Gutterguard", a heavy-duty expanded aluminum screen. This really seems to have reduced the booming sound, while not affecting flow. Sounds like a stock pipe, but with a little more bass and no tweet. The roll is retained in place with safety wire. No more "popping" exhaust note. If it works without problems for 300mi on Sunday, I'll post some pictures. I do a lot of off-roading in semi-legal areas, so keeping a low profile is important. Anybody else have ideas about a quieter exhaust? Devon A15

Bet it won't be long before that stuff burns up. Looks like yet another list veteran is on the way to breaking the Super Crap habit. Welcome to the club. Bogdan

I broke off one of those as well, the tack welds are not very good. I replaced it with a stainless steel nylock nut, and epoxied it onto the core. I will not likely need to change the number of discs again, but when I repack the muffler I'll see if the nut holds, or just spins. And I did slather the copper anti-seize on the threads, it didn't seem to make a difference. The exhaust sounds less "booming" now, I'll see how a long highway run works.

Yeah, I thought about that. But the aluminum is very, very heavy. I have the stuff around at work because I use it to dim tungsten lights when I'm doing interior photography. I have used it in direct contact with a tungsten-halogen lamp without burning. Devon A15 Bogdan Swider wrote:

You need to remember that the Laser is made in Sweden and there are only about 20 (or less) of them on the road in the USA. There is a sparky in there, they just haven't leapt throught the USFS hoops to get the sticker yet. Is there really a commercial benefit for Laser to pass this certification? I'm sure the costs of obtaining this certification far outweighs the potential profit at this time, and they are in business primarily to make money, not to flush it down the toilet like used motor oil. I had my bike inspected by the AMA at LA-B-V and it passed. The only comments I got on the Laser pipe were "What a nice pipe! It's so quiet..." I felt like a positive example of all that is good about motorcyclists in general and KLR riders in particular at that point. Then I unleashed a plethora of refreshment upon my liver and it all went wrong from there. Luckily I was already at the San Remo by then.
