This exhaust really woke up my bike. paired it with the powerbomb headed and the difference is night and day.
I can not say enough good things about this pipe. It have me more power way better sound. Very easy to install and is totally awesome.
This product was as advertised. Easy install, looks and sounds great. Noticeable power increase. Fast delivery. I recommend it!
This pipe is great! It made such a big difference in sound and power compared to the stock pipe on my klx250s. I love it.
This pipe was simple to install, looks good and has a nice sound to it. It's not too loud and it gives a good look to the bike. I didn't notice much of a difference in power between the stock muffler though, but it is just a slip on. Would recommend to someone who wants a pipe that looks good and that is NOT too loud and at a decent price
Bought this slipon for my daughters canam ds 90. The sound and performance exceeded my expectations on such a small atv. My daughter smiles from ear to ear every time she rides! Would definitely recommend this exhaust.
Installed on a 2015 xt250 with k&n air and dynojet programmer. Louder than stock but not annoying. 10 min install. With all 3 items I can go 10mph faster with more responsive throttle. Arrived early. Gotta love MotoSport.
Sounds great not to loud very easy to install on 150R
Nice , easy slip on pipe
Love this pipe! I folded my stock one in half on a crash and this one ads all the power I need. Coming out of corners is much smoother and keeping those high RPMs in whoops are great with this slip on. Easily ads a few noticeable HP. Took all of 2 minutes to install.
The pipe has some gnarly sound and improved my bottom end acceleration. Will buy the header soon to complete the exhaust system on my '06 CRF450r
I put this on my 2015 TTR230 and couldn't be happier. Super easy installation. Gave the bike more power. Sounds great. This pipe is LOUD!
Looks and sounds great what else can I say. Will buy the header very soon to complete the exhaust.
I noticed the power right away, after I tuned my carb a half turn
Very easy installation . Quickest bolt on application to give a noticeable gain in torque and a smoother power curve to give it that low end pull. Can't go wrong with flying machine factory!
Sound great easy to put in gave me a little bit more power
This slip on is awesome. Gave quite a bit more horsepower and torque in the higher rpms. Durable as well. I love it. When installing it, it didn't exactly "slip-on" but it went on pretty easy. Just had to wiggle it to get it to slide on. I got it because I was wanting to get something aftermarket like the exhaust, plus I was tired of looking at my ridiculously long stock exhaust. Glad I got it!
This dirt bike exhaust is just throaty as it can get and it comes with a installed spark arrestor so you can hit the trails with it, i have noticed some really big differences, it seems more responsive like it has the power to do anything, with that stock exhaust the crf has sounds like a baby with this monster on it its like a monster. its not to expensive either so it wont break your budget and its definitely worth the money too.
Awesome exhaust!! Easy to install and sounds great!!
