I saw in the back of the april addition dirt wheels an advertisement for muzzys exhaust sytems for the 400ex and the raptor. It looks good but does anybody know about the performance? It says the muffler is 18" in diameter is that bigger than most exhaust? any info would be helpful. the website is muzzys.com Thanx again

 

Uhhhh, I think they must be measuring the circumference. That being said the pipe would be around 5.75" in diameter, which is still pretty large.

 

okay thanks. does anybody know anything else about this exhaust?

 

on sportbikes muzzy is right up there with yoshi. i think if i was doing it over muzzy would be a hard one to pass up.
