I got my new White bros. installed this weekend and WOW I like it. I noticed some gains down low and in midrange. It has a nice rumble at idle and is just a little louder than I like while riding but I can live with it. This White bros. was designed for a YZ400 and I bought it for $59.99 off ebay brand new. I fabricated some mounts and it worked great. Click here for White bros. pics.

I have been playing with the disc and ended up using 6 discs. I tried 12,10,8 & 6 and found the most power with 6 disc. When I had the 12 disc in it was to loud and I lost my bottom end and midrange power but after I removed 6 of dics the power is great.

 

wait idid you you say it was for a yz 400, am i misstaken or is that a bike by yamaha. I f it is, can you put lile speedbike exaust on a quad is that possible.

 

Yea its from a Yamaha YZ400 bike and long as they are room for the speedbike exhaust on yours I don't see why you couldn't make it fit.
