FMF Power Core 4 exhaust

Installed this on my son's Raptor 80. Fit perfectly and he loves the look and sound. We are very happy with this purchase. Dennis Kirk had the lowest price on the internet and free shipping. Excellent deal, very pleased.

Great Buy

I bought one for my bike and loved it so much I bought one for my wife's bike. I really noticed a low end power improvement on both bikes and the sound is great. I would buy the same pipe again. Recommend a slight main jet increase and you will notice a big improvement in power.

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.

Awesome product Bad finish

Love the muffler just a little un-impressed because there was a huge vertical scratch on the end of it, right behind the sticker.....

FMF sa/muffler

I got the powerbomb header and this muffler together. This was the quickest and easiest exhaust system swap I've ever done. It took less than an hour and fit like a glove. I've been using FMF products for years because they look and sound great.

FMF Loud Pipes save lives

I ordered the Muffler when I was deployed and i informed my wife that it would be showing up at the house. Not to send it back She said ok i well not. she say the price on the in voice. so the next time i called home i got an ear full spending that much on an part. but when i took the outlaw 525 irs out to ride with my new FMF pip just the slip on mind you. at the point and time i started ripping on the outlaw she know the reason I had made the buy of $357.25 my wife said with a smile on her face sounds nice compared to stock I like the Sound
