Here’s a video impression of FMF’s new Factory 4.1 Exhaust with both the Mega Bomb and Power Bomb headers. The full titanium system including the Mega Bomb header retails for $899.99. Individually the Mega Bomb Ti costs $349.99, the Ti Power Bomb is $299.99 and there is a stainless steel Power Bomb priced at $199.99. The pipe bolts right on and gives your bike a factory look while being super responsible with the sound. In fact it not only tested quieter than stock, it sounds quieter than stock out on the track, all while making better power everywhere.
