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?

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.

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.

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.

I am aware that they have a spark arrestor, and considering the
economics I don't blame them in the least for not going through the
government hoops when they (and I) know that they make a perfectly safe,
spark-arrestor equipped high-quality pipe.
Unfortunately, this won't help me if it's drought or a high fire risk
season, and a USFS or Parks official tickets me or impounds the bike
because the stamp is missing.

I've got a Big Gun ready to go on in the spring. Anyone know anything about
them?

IMHO Big Gun is a great pipe for a bike that sees low miles or is a race
bike. Awesome.
But for day to day use, like I ride my KLR, they are too loud, and repacking
a muffler sucks. Especially every 800 - 1000 miles...
You will notice a difference in low end, and the ability to wind out your
KLR, but for me, the Laser Pro Duro is the way to go. I am secure enough in
my heterosexuality that I don't feel the need to hurt other people's
eardrums to prove it.
The Laser is a tad louder than stock, sounds great,and never needs
repacking.
Of course what do I know, it's not like I bought the first Big Gun system
ever sold for the KLR 650.
