THE PROCORE ADVANTAGE

CEL-FREE
Our new ProCore Catalyst provides a downpipe upgrade that passes vehicle readiness monitors without triggering a check engine light.

HIGH FLOW DESIGN
The 6″ 400CPSI CAT removes factory downpipe restrictions to support substantial power gains from ECU tune and turbocharger upgrades.

QUALITY BUILT
Manufactured with quality T304L stainless steel and an advanced molecular bonded wash process for lasting strength and performance.

BOLT-IN UPGRADE
These downpipes are direct-factory replacements that can be installed with the factory heatshield and engine covers for a truly stealth look.
