Non EPA compliant version of our 400 cell high flow cats. These 300 cell catalysts are intended only to reduce emissions for the purpose of reducing exhaust smell, not for passing OBD2 emissions testing. 

Suitable for installation in non-emissions monitored vehicles such as OBD1 applications or offroad/track use, and will cause a check engine light in most OBD2 vehicles without proper tuning.

HP Rating: 350bhp/cat (700bhp per pair)
