Fusion Exhaust Systems

The Fusion is a bi-modal exhaust system, meaning it has two passages, or modes, that the exhaust can travel through the muffler. Each of the mufflers has two outlets, with one side having a butterfly type valve which allows the exhaust flow to be shut off, regulating which side of the muffler the flows exhaust One side of the muffler is the “quiet” side, and one side is the ‘loud” side. The “quiet” side is a smaller, muffled and chambered tube, while the ‘loud” side is 3″ tubing straight through.
