FMF Megabomb Head Pipe with Mid Pipe (Stainless Steel) 044439 - Yamaha YZ450F / YZ450FX / WR450F 2018-2019

Product Description

Optimize your dirt bike's powerband with the FMF Megabomb Head Pipe, engineered to combine the low-end performance benefits of a longer header with the hard-hitting top-end power of a short header. This design delivers improved bottom to mid-range power while being less susceptible to trail damage than extended header designs.

Manufactured from natural stainless steel, this 1-into-1 system works effectively with sound-restricting mufflers, helping reduce sound output by as much as 1.5 dB. The package conveniently includes a matching mid-pipe for a complete, seamless installation.
