Great pipe for the money
Love the sound, but took a little work to get it to fit. The problem wasn't the pipe, it was my bike. The increase in power is reallly nice and it sounds great.

Muffler Review
Installation was easy and fit was good. Product looks well made. I was looking for a lighter than stock unit
with more power throughout the bottom to top range, yet keep the noise level low. This unit came very close to meeting these goals.

Best Purchase Ever
I got this pipe for my 2002 crf 450 took five min to install and was the best pipe for the money, sounds great, looks good, has more power, great spark arrester that comes right out when on the track or where you dont need one, buy one you wont be sorry you cant find one better for the price.

great bolt-on for TTR
Great bolt-on for the TTR! Really wakes up the motor. You need to increase the carb jets to get the most from the pipe. Sounds good, much louder than stock but not obnoxious. Great fitment, took 5 minutes to remove the old pipe and install the new one.

Great pipe for '01 Wolverine
I was worried about getting a pipe that might be too noisy for where I ride, but decided it was worth a try ($200 cheaper than a factory replacement). The pipe is great, and with the quiet core installed this is quieter thanthe factory ever was. The fit was great and the part shipped to me in 4 business days. Would not hessitate on recommending this part to anyone looking for great fit and a quiet exhaust.

Great Pipe- need jets!!
The part itself is great, the problem we incurred was there were no jet kits available for this bike and the local yamaha dealer who installed the pipe had no way to test without trial and error @ $80 per error!!! Jet kits should be included or at least available for ALL models and this part should come with suggestions for appropriate jets!

Great performance, low noise.
I was impressed with the fit and finnish and did see some improvement in low end torque. i was a little let down with how quiet it was compared to my old silencer, but am happy with it overall. I would highly recomend this product to anyone looking for a nice mellow sound.
