Bought this to replace the one we dented. It is of the build quality you expect from Motosport.com and FMF
Great exhaust! Good fit and Quality Fabrication. A noticeable difference over stock when combined with the 4.1 FM F muffler I have used FMF products since the two stroke days and have always been impressed. Made in the USA.
I bought this mega bomb header for my 2017 WR450F. I had already purchased the FMF tuner & spark arrest previously and already ran that before the mega bomb addition. Installation is a bit tricky getting the u shaped tube off from factory, and then finagling the new FMF pipe into place around the head, and minimal space between the frame. At one point I was convinced the engine would have to be moved to get the darn thing in!! After a half hour of some very choice swear words, It finally popped into place.Sounds slightly quieter, and has an amazing low end response that clearly was not there before. Have not had a real days ride with it so cant give a true response on total performance. I can say it looks great, installed together as described, and I'm overall pleased with the entire package. I will add that looking into the internal welds, that they really burned through and left some slag that I did not expect to see. This does create drag on flow....therefore I was hesitant to give the full 5 star rating. I believe that FMF builds a superior well tested product, but I would like to see the detail of buffing out the penetration from the welds.I know I read a lot of comment of how you need a heat shield, or you will burn your boots... and I fail to see a difference from the factory pipe from the FMF mega bomb. The portion of the pipe that has the bellow is far away from contacting anything. I like the fitment!!
Bought the mega bomb,4-1 ex.and the jd jet kit, very happy with the product and the service from motosport
Works great, lots of power, fast off the line.
I️ bought this to add power and dampen the sound, and was amazing by the results. I️ have a 2004 yz250f and you can’t go wrong with the power of the mega bomb. This also has my bike set up with a full fmf exhaust which has been an excellent purchase.
Bought this for my sons bike. It was a perfect fit and great craftsmanship. Made a nice improvement on higher rpm performance.
The FMF Megabomb Stainless Steel Header to fit your CRF250R is a single header pipe, with the same fit as the original from Honda. This will fit with your original Honda Y-pipe and mufflers.
FMF would recommend their Powercore 4 racing muffler, or their Q4 spark arrestor muffler for trail riding. Both FMF and Motosport are temporarily sold out of these mufflers to fit your 07-09 CRF250R.
