If it was a GasGasp yood not have to choose!
This does not look enjoyable
Repacking isn't enjoyable, no matter what type of muffler!
Is there an aftermarket option to replace the OEM?
I don’t know. Having to cut it open and weld 30” of aluminum back together is going to suck.
It's hard to tell from the pics, but maybe is possible to adapt the muffler from a newer model? Probably less work than cut and weld?
A torch and put a shit ton of heat through it worked pretty well. We did the head pipe and the muffler. Sally’s bike is nice and quiet again. I just burnt it till it quite smoking. I did melt the outlet on the muffler a bit but I got it fixed back up.
Both Boomboom and I have cut open older Sherco mufflers, cleaned out the old junk, repacked, and then sealed it up again. I had a friend weld mine back together but Boomboom did something else? I forget what he did.
Just finished burning out the front section of my TRS pipe with great success.
I used an LPG gas torch to get the fire going in the gunk and then used compressed air to stoke it.
If you don't have a compressor you could probably use a leaf blower or even a vacuum cleaner with blow option.
No need for oxygen as air works fine.
There is absolutely no need to fear melting the alloy exhaust as you can keep the casing cool with a garden hose throughout the process. You need to hose it regularly though as it generates serious heat if you blow it hard with air!
I actually rubbed some soap in a few places on the exterior as a warning for over heating ( soap turns black well before alloy melts).
It took about 30 minutes before the smoke stopped coming.
Result- my bike sounds like brand new again!
It was so noisy before!
I miss living in the middle of nowhere. I would have the whole fire department up my ass if I tried this.
The Mrs and I live a few hundred meters from the nearest neighbor so I only got one complaint..
OMG the bike has so much more torque now! Wasn't expecting that.
Anyone with a barky/crackly exhaust has to do this.
I had forgotten what the bike used to run like.
I think I stunted the growth of the corn field across the road when I burnt out my last exaust.
