Hold on

Comments On Feb 05, 2015:This exhaust bolted right on with no issues. Looks good, the added power in the midrange is AMAZING! Still a bit loud but did change the tone.

AWESOME EXHAUST

Comments On Dec 30, 2014:One of the best upgrades I got for my bike. Puts out more power and makes the bike sound deeper and reduces the loudness of the stock pipe a litte bit. Did I mention it looks good to?!

Additional Comments On Dec 30, 2014:This is one of the best upgrades I put on my bike. Cheaper than most other stores. Puts out a noticeable power upgrade. Makes the bike sound deeper with less noise Sounds way better than the stock pipe. Sheds some weight to. Did I mention that it looks good also?!

Fantastic Pipe!

Comments On Dec 17, 2014:I simply love this pipe. It seemed to me to open up the mid range the best. The sound is pretty loud but I love it.

Awesome Pipe!!!!

Comments On May 01, 2014:I just bought my bike and the pipe came with it, so I don't know what it's like without it. But I absolutely love it! I love the way it sounds and adds great power to the bike. Everyone I've shown the bike to say they love the pipe on it. Would recommend to anyone!

be like Bubba...

Comments On Apr 09, 2014:...except the crashes. I have ridden with the ti system as well, do not think that the more $ you spend, the more power you make. the stainless system does what its supposed to do and looks great too. this thing hold up to mx and tip overs. header doesn't get dinged up from rocks like a soft ti header. let the rich people buy the expensive stuff. for guys like me, stainless is the way to go. put the other $500 toward your suspension.
