The exhaust now has the low bark I was looking for without a lot of extra noise. The exhaust tip is much larger then stock allowing for better air flow. The bike has better low end power, but is still very linear. No tuner is needed for the bike to run well. I did do the exhaust tune and it did feel a little crisper on the throttle. Well worth it.
I replaced the stock muffler on my '15 WR450F with this slip on and I love the sound. The electric start also performed better with the reduced back flow.The instructions were very easy to follow and the muffler went right on where it was supposed to. I have only put on less than 5 hours since installation so I cannot speak to the durability, but so far so good.
I put it on my 2016 yz250f and it opened my power up more and it also has a great sound when it runs so worth the money!
Instalation was a breeze, looks great, sounds amazing, and made theasy bike feel more responsive.
The sound quality is amazing, i enjoy the sound very much. I personally think that i burn cleaner off the bottom end compaired to my buddys bike which is identical just stock muffler. Lots of torque off the bottom end.
I have a Powecore 4 on my WR450 and love it, so when I got my new YZ450 it was a sure thing I was getting the same pipe.
