Sounds amazing!
I recently had a friend crash my bike causing the my stock muffler to be sandwiched to kingdom come, but I couldn't believe it when I saw the OEM replacement cost $791.00. So I got this on sale (430$ I believe) It was extremely easy to put on, ups the bikes value, performs better than stock (I could feel better throttle response), and it sounds Sooooo much better than stock. If you want to upgrade your bike for looks/performance/sound, I would absolutely recommend this.

Great exhaust! I don't think it was worth the $405 I paid for my bike but I still think it was a great upgrade. Awesome sound. It gave my bike a little bit more low end, But I wish it was still better. Very easy install and I am still happy I bought it!

Perfect exhaust
I had the FMF 4.1 titanium before and the exhaust is just as loud without the silencer insert installed but still sounds crisp and comes with adapters for factory header as well as FMF headers!

Great Pipe
Awesome upgrade from the stock exhaust on my drz with the power bomb header. Fit perfect. Haven't tried the spark arrestor yet but im sure it would quiet it down if needed. Definitely barks and adds a lot more to the experience of riding. Sounds like a real dirt bike instead of a sewing machine. Quality built and im sure it saved some weight too.

Do this mount up with the FMF power bomb header you guys sell as well? Looking for a header and slip on combo, just want to make sure it all lines up. Thank you.
Yes, this can be mounted with FMF's power bomb header. To ensure you are ordering the correct parts for your bike, be sure to enter the year, make and model of your bike on the product page to confirm fitment.

Do I need to rejet my 2002 Honda trx250ex if I only order the slip on exhaust muffler
Full exhaust systems will almost always require an air-fuel adjustment. Conversely, slip-on exhausts usually do not need one. With that said, we would recommend that everyone tune their air-fuel mixture after an exhaust modification. Even if it isn't mandatory, a jet kit or fuel controller will always be beneficial.

I have a 2006 crf250r dual exhaust stupid question but does it come with 2 pipes if I order the muffler lol
Hi, no the FMF PowerCore slip on pipe for your 06 CRF250R comes as a single pipe.
Hope this helps!
