ZZP brings you a high flowing premium core catalytic converter. Our 200 cell cats use a metallic substrate spun core; our 400 cell is ceramic. Testing on the flow bench and the dyno has shown these converters to out perform anything else currently available in the 3800 market.

400 cell is 5" in diameter and is 8.75" inches long.

200 cell is 4" in diameter and 8" long.

Our high flow catalytic converters are EPA certified. If your state requires CARB compliance, these do not meet that CARB standard. Please contact [email protected] if you have any questions.
