MIA's Description

The Kooks 3-inch Green Catted Y-Pipe (MPN 37103300) is a high-performance exhaust component designed specifically for 2007-2018 Jeep Wrangler JK models that have been converted with an LS engine swap. Constructed from durable 304 stainless steel with 3-inch mandrel-bent 16 gauge tubing, this Y-pipe is engineered to significantly improve exhaust flow, leading to increased horsepower and torque. It features Kooks' "Green" 300-cell high-flow catalytic converters, which are designed to meet Federal EPA standards and prevent emission-related Check Engine lights, while supporting forced induction applications up to 750 RHWP.
