Awesome pipe!!!
I put this pipe on my Crf450 and it dramatically improved the throttle response, and totally eliminated flameouts/pop stalls.

Awesome
This pipe adds tons of power! I was really surprised how much i noticed it, it added power everywhere. The low end power is really brought to life on my 2010 crf250r. Install was simple and so far after about 5 months I've had no trouble at all. Durability seems good too. GET IT!!!!!

Excellent Product
One of the best products I've purchased and a must have for the '09 CRF450. The '09 CRF450 falls on its face at about 8200RPM, but this pipe adds about 3+hp on the dyno and brings peak power to about 9500RPM which is a massive improvement. I didn't realize at first, but I thought the included 94db insert was missing when I unpacked everything. Turns out it is pre-installed and you can see it in the product photo. The pics I added are the pipe without the insert (99db)(almost 1hp gain) and the free exhaust plug and spring puller that come with the kit. Don't bother with the full carbon kit. It only saves 0.2lbs over this full titanium and carbon will breakdown as the packing wears out. This drops over 2.0lbs from the stock unit. Oh and Titanium is the easiest to maintain(clean) material there is. The stainless calls for occassional polish every few hours of use etc.. So far I love this new setup and it looks totally trick!

This exhaust system will be 99db out of the box but will include the 94db insert.

No.. It only comes with a 94db insert. You can remove the insert which makes it 99db and adds about 1hp. The photos are with and without the 94db insert installed.
