White Brothers MX-4 slipon

[400exnewbie]

anybody have one of these? i searched and didn't come up with much.

anyone that has one how did u like it? how loud is it? it says it comes with hte required jetting but will that jet work for a 450r with a dropin K&N and a cut airbox?

i am thinking about getting this slipon and would like to know how it fares against the rest of hte slipons out there.

thanks

I have one and love it. Kind of loud but has a throaty sound. As far as jetting, get a dyno jet kit or something comparable.

how much louder is it than the stock pipe with the spark arrestor removed? i am really not too worrid about the loudness as long as it isn't WAY loud, i am just looking for a good power increase.

how does it compare to rest of the slipons out there? hows the quality?

i have one on my '05 450r and i like it a lot. it sounds really good and the power is real smooth. the paper work that comes with it says that you don't have to rejet if you leave your lid on. so i just slipped it on and wow. i beat a 04 450r with a hrc kit and a carbon pro. on the top end i stayed even with a yfz 450 and off the gate he would get me by about 1/2 of a quad. very impressed.
