excellent exhaust

I purchased this exhaust system a week ago, and I must say it's the best! I put this on my 2005 crf150f and the increase in horsepower and throttle response is 10x better! On a side note I did have to pry apart the rear mounting bracket a little bit. And also the pipe sounds really great......it's like night and day compared to the stock pipe......it's also much louder by at least 60% I don't think my neighbors like the sound haha.....bottom line get this for horsepower and throttle an sound increase you won't be disappointed!

It gave my KLX nice sound, quicker throttle response and better performance across the powerband. I dont think you can go wrong with Pro Circuit products.

This PC exhaust system is worth every penny. Sound & quality is beautiful. The sound is quiet thru loud depending if you are using the quiet insert that is supplied. The reason why I gave fitment 4 stars is because I had to pry the welded brackets on the muffler wider to go over the rubber grommets on the back subframe where the long bolt goes through.

Pro Circuit T-4 exhaust

Put this on a 2002 TTR 125. When the exhaust arrived I was a little nervous because it came in 2 pieces, the muffler and the exhaust pipe. I thought I would have to make some alterations to the mounting to get it to fit. But it mounted perfectly without any modifications to the mounting brackets. This system was added for extra airflow after we "swiss cheesed" the airbox and rejetted. Sounds real throaty and makes the 125 sound like its got some muscle. Also, it is noticeably lighter than the stock pipe. Kind of pricey, but our options were limited for the TTR and we needed more airflow thru the motor.

Great Performance Boost

I bought this pipe to increase performance as the stock exhaust was very restrictive. The new pipe bolted up easily to the machine, but was resting on the pull start handle. This was a problem that I needed to correct. I ended up having to heat up the pipe and bend it so it would not touch the handle. This did not go smoothly... For the money this kit cost, fitment should have been better. I also installed a jet kit at the same time which has the machine running perfect. Overall I am very pleased with the performance increase and construction quality of the kit.
