The ISR race muffler delete for 2016 and later Mazda Miata ND removes the factory muffler section and installs a straight-through pipe tailored to ND chassis vehicles. Intended for motorsport or track-focused applications where the muffler section is intentionally removed, the unit fits ND exhaust layouts and integrates with existing mid- and rear-pipe components as required.
