Very happy about the buy.. went right on no problems .. Did burn my boot a bit no big deal.
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.
ive had this on my bike for a few weeks now and its slip on is rattling but the header and stuff is all good. idk the hp gains but it sounds great
Installed on my 2014 YFZ450R, Love the look and power of this pipe , I paired it with my big gun
evo R slip on , had a hard time finding out if it would fit so I'll make it easier on you it does fit this slip on
Decided to add the Megabomb header to my previously installed FMF silencer. Very light weight but not as solid as the OEM header. Installation was simple however joining to the FMF midpipe/silencer was difficult. Even with high temp grease, difficult to join together. I have never had this problem with FMF before. Likely just a "one-off" thing. I have already purchased a carbon heat shield to place over the header - you will burn your boots/pants if you are not careful.
Unable to detect a power increase but slightly more responsive throttle. The biggest change occurred when I installed the FMF silencer 6 months ago. It will give your bike that factory look.
