Features

This 2 piece Mazda Miata performance exhaust features a front pipe and a mid pipe that mount to the header and showcase an integrated muffler. The front pipe is 2.5'' and features brushed stainless steel construction. The rear pipe has a polished, stainless steel muffler that’s accented with a 4'' tip. In addition, NB Miata exhausts come with a secondary o2 bung and o2 bung extension made for drivers who use the factory ECU, and don’t want to use a CEL.

Perfect Momentum Support

This Miata performance exhaust supports maximum driving momentum in two ways. First, it supports powerful, efficient combustion by quickly piping out fumes from the exhaust manifold. Second, the exhaust configuration weighs in at 18 pounds less than the vehicle’s stock exhaust. However, we should note that this exhaust hasn’t been tested on the turbo mazdaspeed model. If you need an ISR exhaust for this Mazda model, we can create one, or order what you need.

  1. great product

    Posted by Zach on

    Easy to install came with all hardware and gaskets necessary. Sounds amazing. Best exhaust for the price on the market,

  2. great deal with sound

    Posted by MJDNB1 on

    I was looking for a good sounding muffler for my NB1 and after searching the web and finding a lot of choices with over price exhaust systems I finally got the ISIS not knowing how the outcome was going to be, but after spending 35 minutes with full installation i was blown away. So much better than I though and no rice sound, deep enough to enjoy conversation with soft top but a good high RPM sound. The way the muffler looks its the best fitment I ever seen, very professionally made, looks serious and not some 60 dollar fartcan. I will recommend this exhaust system to any aggressive miata out there.

  3. Love love love this exhaust

    Posted by Finn on

    The box came well packaged, welds on the piping were on point and the hardware was topnotch.

    You will love this on your NB. Considerably louder anf deeper tone up to about 4500rpm, once past that the note changes almost back to stock but with a more aggressive tone all the way through redline. Absolutely no rasp as well anywhere throughout the powerband.

    Absolutely no droning to be heard, even with my 6spd which turns over 3500-4000rpm at cruising speed. Another plus is that weighed against the stock system youll shed 18lbs dead weight.

    Only issue I have is that I cant seem to get a tight seal at the resonator section. I've messed with it already but to no avail. This might not even be a issue with the product, it might lie with my down pipe.
