nice pipe
this was well made but the T-4 4-Stroke Silencer Part #448937 didn't fit my stock 2001 drz400s head pipe, It looked well made but i sent it back , Not sure if a different part number would have fit. I ended up just getting a full system from another maker.

More power better sound!
Bought for my '95 KLX650R and am very happy. I replaced a cheap aftermaket silencer that rattled. Huge upgrade! Fit perfect sounds awesome, and better power.

Nice Pipe
Good sound, good power. Quiets down considerably when at cruising speed. I needed to re-jet but that helped with power as well.
