The HPI Sports Catalyzer for the S14 is a direct replacement for standard restrictive catalyzer setup. With the high flow design this item will prove to be a great upgrade while keeping exhaust gases clean. It is illegal for shops to remove your catalytic and to get caught without one will get you a huge fine. Stay street legal with the HPI Sports Catalyzer.
The diameter is enlarged to allow your engine to exhale the hot exhaust gases more efficiently, increasing horsepower at almost any RPM and tuning level.
