Great alternative to the FMF.

By   on  Verified Purchaser

Great pipe. Some say it's too loud but it's just perfect in my opinion, but I'm used to short shots on a Harley. It's pretty quiet until opening the throttle at which point it has a nice "bark". Seems to be of good quality, as with most Pro Circuit hardware. Easy install, no leaks and didn't install any gaskets. Good purchase. Rated the value a "4" because slip-on pipes shouldn't cost 300+, but what can you do, the market is the market.


Great Pipe

Took my buddy's recommendation and purchased this for my CRF250. The muffler sounds great and was a no-modification installation.

Is it better than a stock warrior muffler

Yes! A Pro Circuit T-4 Slip-On Exhaust for the Yamaha Warrior will be an improvement over thst stock item in a few different ways. First, it's lighter - everyone likes a little less meat on their machines. Second, it's made of aluminum and stainless steel, so it won't rust or corrode over time. Third, it flows more air than the stock muffler, so when jetted properly with, for example, a Dynojet Carburetor Jet Kit - you can expect improved engine performance and throttle response, more power all around. And everyone likes more power!
