ISR Performance RC Series Muffler Delete - Mazda Miata NC 06-13

The ISR Performance RC Series Muffler Delete for the 2006-2013 NC Miata is a track-focused axle-back that removes the rear muffler entirely. 2.75" stainless piping flares to a 3" tip, and the deletion shaves around 21 pounds off the back of the car compared to the stock muffler.

What It Does

Race-focused axle-back replacement. Deletes the factory NC 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. The 21-pound weight savings is significant on a Miata. Gasket included for a clean bolt-up. For a full catback rather than a delete, see our IS-CSEXH-NC Circuit Spec Exhaust for the NC Miata.

Fitment

Designed for the Mazda Miata NC (2006-2013). For the ND1 (2016-2018), see IS-RCE-NDMD (same RC Series muffler delete style).
