If you’re looking for an affordable, lightweight, race-style exhaust system for your ATV, FMF’s Power Core 4 S/A Exhaust manages to deliver all that in addition to a few extra perks and the legendary build quality of FMF.

Simplicity is a big part of the exhaust so FMF uses a straightforward oval canister of lightweight aluminum and stainless components. Not only does that provide a very clean looking package, it delivers unhindered exhaust flow that boosts power and provides a weight that is much, much lighter compared to your machine’s stock system.

But FMF provides refinements too with removable hardware for easy repacking/servicing, a removable USFS approved spark arrestor, and an optional noise reducing end cap insert. So you have the ability and performance to use the Power Core IV anywhere you want to ride.
