KPower 3-Inch Race Exhaust System

The KPower 3" Race Exhaust System (V2) is a stainless steel, 3-inch diameter exhaust designed for off-road use on NA and NB Mazda Miata models (1990-2005). This system features a resonator and a straight-through oval muffler, enhanced with all-stainless steel packing to ensure a longer lifespan, particularly beneficial in racing environments. It is designed to bolt directly to the K24Z3 downpipe, and customers using a K24A engine with a 4-2-1 race header may need to purchase an additional midpipe with a flex coupler. This exhaust system does not include a catalytic converter, making it intended solely for off-road competition use. Due to its routing in the same location as the factory exhaust, it is compatible only with NA and NB Miatas equipped with the factory Miata transmission and differential. It is explicitly not compatible with vehicles running a BMW transmission or a Getrag differential, nor is it compatible with early NA four-bolt axles. These compatibility restrictions were necessary to maintain adequate ground clearance.
