250-500cc 2013 WR300 - Shortening stock muffler?

Has anyone done this? You can cut the muffler from the opposite side to the outlet to bring the length of the muffler shorter and a bit more hidden under the plastics.

Will this change the note and or performance of the bike itself? If i can just get away with cutting this it may trump buying a new slip on as i want the stock look.

Thanks all.

Was only looking to trim around 2 inches off it, redrill holes and refit. Just to get the outlet snout in line with the plastics. And maybe a bit for noise... lol

i thought shorter = more bottom on a smoker?

but look cooler & thats the main thing! i got a brand new PC plat 2 & 304 silencer you can have cheapish if you want aftermarket or if you want a stock silencer to butcher pay the postage from my way with some xxxx for good measure & you can have mine mate. sitting there doing nothing anyway. i got a shorty Q stealth on mine

I've run stock and shorty mufflers on my bikes and never been able to tell any difference in power. It will absolutely not affect jetting. It may be slightly louder.

I dont get the point of this..

To bring to end of the pipe back in line with the plastics. Will look better in my eyes and its free to do. Thats why.

longer silencer equals more leverage on subframe mounts in a crash so more chance of bending/cracking em too(i found this out!)

Ok makes sense. Just curious

i cut the stupid little pea shooter tip off on mine too then got a mate to just weld the remaining ring. looks similar to the ktm stock silencer-much better!

Thats the go Shawbagga, would look nice and clean on the back end.

Your mounts won't line up. But Uptite I think shortens them for a performance gain. But I believe he does more than just shorten.

if you just chop say 100mm(4") off the end it doesnt affect the mounts whatsoever, chopping from the stinger end will. what more can you do to it other than shorten it(genuine question) wait4me?

I don't remember what all he does.

I reckon cutting 180mm(I measured mine) off from the welded base area of end cap, then reweld end cap back on would look sweet as neesmo. I might give it a crack when I get a chance! stock shorty. the stocker is a rocket launcher & heavy

Yeah mate thats what i reckon. Keep it hidden under the plastics and will discharge lower so you dont get a sooty blinker

Or put a droopy on there - i love the look of the old school 2 smoke mufflers.

yeh I remember when that look was all the rage haha. just weld one on there!
