Nice product
Got this for my 2001 drz400s fits great. All the bolt mounts lined up, no need to mod. parts. Finish is A+ like all Yoshimura products. Sounds nice, not to loud at an idle.
Remember to get a new gasket (where pipe goes in to the head) with this cause it doesn't come with one.

Another amazing Yoshi Product!!!
I Love Yoshi.. I installed this on my 2006 Suzuki DRZ400s and i absolutely love it! It sounds great.. I also did the 3x3 mod and jet kit and wow did it wake this bike up :) the yoshi system installed very quick and easy and fit perfect! The silencer insert def makes a big difference in the sound.

BUY IT!!

Nice Exhaust, Terrible Fit
I bought the exhaust after hearing a couple good reviews from my buddies. I got it, it looked nice, but it took me a full day to put it on. I couldnt figure out why the mounting holes wouldn't line up. What i ended up doing is cutting about 3/16" off of the header. Everything went together smooth after that. It has a nice sound but it is really loud.

did not fit
Ordered this exhaust for my 2008 Suzuki DR-Z400SM did not fit the head pipe was to large for the exhaust port. spoke with Yosh factory. Said they had several of these systems that were packaged wrong. returned the Yosh for an FMF.
