These mufflers start as round 4-inch tubes, then bell out to 4.5-inches, for an aggressive and classic design at the rear.

We then roll the end of the muffler tip to give them a clean, finished look. Internally, these NH mufflers have a spun and louvered baffle, but only for 8-inches.

This is done in order to produce an aggressive bark with great performance.

At the end of the baffle is a trumpet shaped inner tip that works in harmony with the belled end, creating a unique look.

RIDE LOUD!
