The FMF Powerbomb and Q4 Muffler are legendary in the exhaust market.

The Powerbomb header promotes better flow by allowing a small expansion of the exhaust gasses improving scavenging. The 'bomb' also acts as a pre-muffler taking the edge off of overall sound levels.

The Q4 muffler employs intricate chambers, baffles and proprietary multistage packing material making it the best performing quiet muffler available with a sound output of 96dB; with most models below 93 dB. It is constructed from aircraft grade aluminum and high strength stainless steel.
