Description

The JHMotorsport JHM-B8S4DPXCAT is a pair of high-flow catted downpipes engineered with an integrated baffle system. Designed as a direct OEM replacement, these downpipes are easy to install with basic hand tools and require no cutting or welding. They feature JHM High-Flow Cats positioned further downstream to alleviate engine heat build-up and increase catalytic converter longevity, while also maximizing power throughout the RPM band and increasing low-end torque. The downpipes utilize a JHM V-Band connection for simplified midpipe integration.
