ISR Performance RC Series Muffler Delete - Mazda Miata ND1 16-18

The ISR Performance RC Series Muffler Delete for the 2016-2018 ND1 Miata is a clean, lightweight axle-back replacement that removes the factory rear muffler entirely. 2.75" stainless piping flares to a 3" tip, and the muffler weight disappears off the back of the car for a noticeable improvement on track.

What It Does

Race-focused axle-back. Deletes the factory ND1 rear muffler, replacing it with a straight section of 2.75" stainless piping that flares to a 3" tip. Lighter rear-end weight, more aggressive sound, and the kind of track-only solution where weight reduction matters more than refined acoustics. Gasket and hardware are included for a clean bolt-up.

Fitment

Designed for the Mazda Miata ND1 (2016-2018). Not tested on ND Club models and may interfere with the Club's bumper cover. If you're running an ND1 Club, verify clearance before committing to the install.
