Jackpot Dyno tuned 4" mufflers feature our legendary Fuel Moto dyno tuned baffle system designed from countless hours testing different baffle designs, configurations and dyno tuning to offer the best performing slip on mufflers available.
Available in an unrivaled show chrome finish.
Slash Up matching the cut of the saddle bags or Slash Down cuts available.
These mufflers were designed specifically to be used with the stock Harley head pipes, as well as a stage 1 air cleaner and Dynojet Power Commander (or appropriate EFI tuner).
Jackpot mufflers offer the ultimate combination of performance and sound. The sound quality of these mufflers is truly second to none. Jackpot Dyno tuned mufflers provide a deep, rich tone that provides a true V-Twin note. They emit a very reasonable sound level in the idle and cruise range areas, and a nice powerful rumble in the upper RPM's.
During the development, customer feedback was crucial as well years of riding, tuning, and selling exhaust systems to real riders who were looking for mufflers that were "not too loud, & not too quiet". We developed a muffler that after a long day of riding you will still say "these mufflers sound awesome" They truly offer a big pipe sound at a lower volume.
