Available at a far more friendly price point than the higher end FMF mufflers, the PowerCore 4 HEX is one of the best value-for-money muffler upgrades you'll get your hands on.

These things offer an improvement in torque and responsiveness, an increase to the horsepower of your machine, and offer some solid long-lasting durability, all at a price that won't have to mortgage your house for.
