Product Details

Constructed from 304 stainless steel, this ISR Performance Circuit Spec exhaust system is built to handle the demands of spirited driving on your 1994-1997 Mazda Miata NA with the 1.8L engine. It’s designed to replace the factory cat-back section, improving exhaust flow and giving your Miata a more aggressive sound profile. The 304 stainless steel offers good corrosion resistance, which is important for a component exposed to the elements underneath your car.

This cat-back system features a straight-through muffler design, which helps reduce backpressure compared to the stock muffler. This can lead to a more responsive feel from the engine, especially at higher RPMs. The piping diameter is optimized for the 1.8L engine to balance flow improvements with maintaining good low-end torque. Installation involves removing the factory exhaust from the catalytic converter back and bolting this new system in its place. You'll want to ensure you have the necessary hardware and potentially new gaskets for a clean installation.

When installing this exhaust, it’s a good idea to have a helper to support the weight of the system as you work. Ensure all hangers are properly seated and connections are secure before tightening everything down. This system is intended for off-road use and may not be emissions legal in all areas, so please check your local regulations before purchasing and installing.
