The FMF Powerbomb header is the result of countless hours of research and development on and off the track seeking to maximize power from the exhaust system.
The unique design of the FMF Powerbomb header provides room for the expansion of the exhaust gases creating a 10% increase in exhaust flow. Translation: more power.
The larger "bomb" section of the FMF Powerbomb header creates more surface area to increase sound dissipation and lowering the dbs. By decreasing the sound level, your bike will more easily meet the tight sound restrictions.
The FMF Powerbomb header is constructed out of light weight and durable Titanium.
I noticed a big difference in power. I dropped my bike once and didnt do any damage but my boot rubs on the power bomb and makes black on it but it does come of easy with a brillo pad without scratching the pipe
Huge gains in power and looks good. The only issue was I dumped my bike at very slow speed and it hit a SMALL rock which put a small dent in it. It seems my steel pipe put up with more abuse than this one. I was expecting titanium to be stronger.
I have a 2004 WR 450 and I have used with fmf power core myself along with factory WR and YZ pipes. I purchased the stainless steel version in 04 and has held up with no dents or bends from the occasional drops or crashes.
are you referring to an FMF slip-on? If so, yes this will compliment your exhaust system just fine. If you referring to the stock exhaust, FMF will not claim their header pipes to work or fit properly with the stock/OEM silencer. If you don't have the FMF slip-on, I would suggest investing in that first before the header. You'll get more performance from the slip-on than just the header alone.
