FMF MegaBomb Stainless Steel Header Pipe

The FMF MegaBomb stainless steel header pipe (exhaust header) is a performance header for 4-stroke motorcycles and ATVs. It is built to improve engine output while keeping the noise level down. The MegaBomb uses FMF's expanded midsection design. The design aims to give the low-end torque of a long header and the top-end over-rev of a short header. It is a bolt-on upgrade that is used by factory race teams.

Key Features:

• Broad power gains: The design improves low-end to mid-range power and broadens the mid to top-end power over stock.
• Power increase: FMF says a MegaBomb can add as much as 3 HP over the stock exhaust.
• Lower sound output: The larger midsection gives more surface area for sound dissipation. FMF says it reduces sound output by as much as 1.5 dB.
• Premium stainless steel construction: The header is made from American stainless steel for durability and long service life.
• Compact design: It is shorter than a true long header. That makes it less likely to snag or be damaged on the trail or track.
• Muffler compatibility: It pairs well with FMF slip-on mufflers and sound-restricting mufflers.

Intended for closed-course competition use only. Not for street use. The MegaBomb suits motocross, supercross and off-road riding, including GNCC-style trails. Choose the header version made for your machine.
