How do you make an XR200R sound good?

**oldskool** · 13th October 2008, 14:26

Waaay back in the 80's when I was just a... you'd just bolt on a supertrapp (or drill holes in the can), these clappers don't seem to be available now.

Anyone had experience with using a muffler from a pitbike or a Hummer on a small barrel jap bike? It looks like you can get them cheap enough from TM.

I'm not after performance gains, I'm after a deep throaty sound. But having said that I don't want to stuff my exhaust valve either!

Any suggestions welcome!

Theres some goon in wellington who makes noisy exhausts. I forget his brand name. Apparently they sound really good and they're cheap.

Um yea buy a bigger bike, or hunt around some of the older bike wreckers for the original supatrapp.

One of these bad boys - check for inlet pipe size as there are three options on this website.

Its USA so works out about $100 NZ PLUS shipping.

cut the exhaust off
those NC series motors sound better with straight pipes

Would that be the Koby Muffler?

I had a similar looking supertrapp with the sprung loaded single nut adjuster on an XR500RC, and it just blew off on the first blast. It used a weak hook system to hold it to the can. Once I got that fixed I lost the plates on my next ride as the loctited single nut just unwound with the thumps. Maybe on the 200R it might work.
But looks like that price may not include the plates.

The wreckers up here in AKL don't have any.

Tell you what you can get in NZ is a 425 mm shorty megaphone muffler in chrome (bling for the XR). They have a removable end so you can muck around with the packing etc if required. Be warned they are 'loud'.

Under $100 bucks Emgo or WFO brand if I recall.

This would suit the bike.

20yrs ago it'd be the mandatory Powroll Kit

Current best option for the job would be a Musket muffler

Drill a hole in the stock exhaust.

Sadly I'm not a *bling* type guy

, if I wanted to pimp up a dirt bike I'd get another TT500

425mm is just too long, I'm thinking along the lines of a BBR style pitbike can.

How awesome, thanks for the tip, http://www.mlbnz.co.nz/musket.asp
I'll be needing a manifold bend one day as mine has a bit of a dint in it. (from what I gather it is the length and bend of the pipe that tunes the all important impulse wave and the can suppresses the bark) Unfortunately they appear only to specialise in replicating stock mufflers, they do have a small range of 'universal' mufflers but I don't think their aim is to sell an aftermarket tuned can.

Heres an example of what a HUMMER 200cc muffler sounds like

and what a Honda CRF450 sounds like

There really isn't a lot in it, except the 450 is revved out higher to make all that air.
So what I wanna know is has anyone adapted a china made muffler to a jap bike and do I need to change the main jet?

when i bought mine from my uncle it had his homemade muffler that did very well til i munched the pipe in a race accident - my re-welding was just too brittle and would break by fatigue every 100 hours or so, so i went scrounging around the local engineering workshop skip and made my own 'tunable' one from some stainless pipe and RHS with aluminium endcaps

but if you want you could have my old muffler my uncle made - will need welding to a pipe
