I was thinking about putting a new exhaust on my 2002 YZ 125. I like the FMF and the PC systems, but I want something different. I seen the BILL'S PIPES and was wondering if anybody has used this system or has heard any good or bad on them.I have the stock exhaust on the bike now, I know the OEM exhaust is great..just looking for maybe a little different sound and bling any comments.... Thanks guys and MERRY CHRISTMAS everybody!!!!
