ISR Performance Race Muffler Delete - NC Miata (06-13)
ISR Performance Race Muffler Delete removes the rear muffler and is a quick and clean solution to losing weight, and giving your NC that extra edge at the track. This is compatible with the stock exhaust or the ISR complete exhaust.
ISR Performance Race Muffler Delete drops roughly 21lb's compared to the stock muffler
2.75in stainless steel piping that flares to a 3in tip
I bought this and put it on my 06 base model. The header and midpipe are stock, and my only complaint is that the flange on the ISR piece isn't exactly perfect with the stock midpipe flange. It fits and bolts on, but if we're being picky, it takes some persuasion to make it fit. That said, sound is excellent with minimal drone at highway speeds and deceleration. It fits great at the bumper cut out and doesn't look out of place at all on an NC1. Shipping was fast and packaging was excellent. I'd recommend this muffler delete and would definitely buy it again.
