DL1000 stock exhaust mod.

[PapaWally]

Anyone able to explain this mod.?

peeshooter completely gone

[jfd3220]

Looks like someone totally modified the muffler. It doesn't look like that when you just remove the peashooter. You can see 2 welds on the edge of the inner pipe. Someone on the VSRI forum turned his DL650 muffler into a straight-through pipe. That's what this looks like. I've been thinking of doing this but need a couple of cans to work with.

That pic is not from a DL1000, maybe a 650.

If you drill 4 - 6 5/16ths holes in the outer ring of both mufflers you will be very happy with the sound.. I had a set of Scorpions on that I felt did not like and were too loud.

I found the 4 holes I drilled to be just right... Nice bark to it but not loud.

I took a 1"(I think) hole saw and went straight in the end of the pipe. I used the size that just fit inside. If you drill through the first layer that you hit you will then be able to see the muffler core. This mod keeps the stock look but does open up the exaust a little. The sound is slightly louder.
CAUTION<<<This will make a lean running bike run worse.>>>CAUTION

looking down the 1000 peeshooter, the baffle just takes a turn about 12" inward. Thus I see no flat surface to holesaw????

I understand the options are

1 - cut peeshooter short near weld
2 - drill 4-6 small 1/4"-5/16" holes between pee shooter & chrome outlet
3 - do both

comments?

Forgive me for posting a link to that OTHER website

I like the sound of the referenced video clip

Was this really just shortening the peeshooter?

[PapaWally]

I thought the Wee had a chrome outlet

whats a couple pipes predrilled worth to ya?

[PapaWally]

Hummm, I could experiment!!!!
They are heavy, how much do you think shipping to Ohio would be?

If you are going to "ruin" your exhaust, at least do it like Handyhiker has told you...anything else is just leaky holes in your exhaust.;) I drilled my old cans before I got my Leo Vince exhausts, and I wish that I never had done it.

[PapaWally]

Don't get me wrong, I'm the last one who wants the drilled leaky sound.
I don't understand handyhikers 1" holesaw suggestion.

Just looking for a deeper v-twin sound w/o the $$$$

Send him a private message, he can explain it allot better than I can.

Big B,

Have you ever come across a section thru the internals
of the 1K muffler?

[handyhiker]

Here are a few pics of how to do the exaust mod on a stock muffler. This makes the bike slightly louder, run slightly leaner, and gives a little bit of a deeper tone.

This is the drill bit I used. It is a 1" hole saw with an extension shaft.

Insert it into the end of the muffler.

After drilling through 1 wall inside the muffler, you can see how far it will go in.

And when you are done, it still looks stock.

I seeeeeee Very Interesting! THANK YOU!
Did some more looking and found this on youtube

Does this clip sound similar to your Vee?

[PapaWally]

Ok, I listened to the earlier posted link again...
http://11109.rapidforum.com/topic=121075115393
and just noticed that this is jfd3220's sound clip
I like it!

jfd3220, could you confirm?
Would you be kind enough to describe your mod. process?

thats my video of my mod.

Fatal Error,

Would you be kind enough to share the description of the mod.?

[jfd3220]

Actually the second post in that thread explains what I did. Here it is:

If you look at the end of the muffler you will see 2 coaxial cylindrical lengths of pipe with maybe a little more than 1/2" of space between them. You want to cut the inner one. If you look between the two pipes you can see where the inner pipe is welded to the circular plate that is the end of the muffler. Just make sure you cut on the outside of the weld, otherwise the pipe won't be attached to the end of the muffler (the plate) and you will get leakage from the baffle chamber and probably rattling from the pipe as well. I used a dremel (rotary tool) with a fiberglass cutting disc to cut off the peashooter, just stick it in the inner pipe and cut it from the inside. If the diameter of the disc is too big just cut something hard and wear it down so that it fits. To figure out how deep from the end to cut just stick a ruler between the two pipes and see how far in the plate/weld is from the end of the inner pipe. It's better not to cut deep enough than to cut too deep. If you don't cut deep enough you can always trim it down. It only took a couple of minutes to do both sides.

I think that if you drill holes in the end plate, which I also did and do not regret, and don't like the sound you can just tap the holes and stick some short bolts into them.

Here's another link
The drilling of the back plate most be in reference to the wee-strom?

I just drilled some holes in the end plate. It now looks like this:

[jfd3220]

In addition to removing the pea-shooter I also drilled 8 holes. I don't recall the size. It's something like 3/8" or 5/16".

[jfd3220]

I cut open a couple of mufflers which I intend to modify this way: http://www.raceratb.com/austin/car/vstrom/muffler.htm
The insides look the same in the Vee as in the Wee.

[PapaWally]

Well, I cut the pee-shooters flush and I like it
The RH side is much loader than the LH side
I assume this is due to the more direct routing of the pipe
I might suggest leaving the RH pee-shooter @ 1/2" Lg.
while cutting the LH flush.
My opinion FWIW
