PLM Cat-Back Exhaust – Jeep Wrangler JK (4-Door)

SKU: PLM-EXH-JEEP-WRANGLER-0718

Upgrade your Wrangler JK with a durable, high-clearance cat-back exhaust system designed for improved flow, better sound, and off-road practicality.

The PLM Cat-Back Exhaust system replaces the restrictive factory rear section with mandrel-bent stainless steel piping for smoother exhaust flow and enhanced tone. Designed specifically for 4-door JK models, this system improves ground clearance with a pre-axle turndown tip — ideal for trail use and off-road obstacles.

Whether you’re daily driving or hitting the trails, this system provides a deeper, more aggressive exhaust note while maintaining durability for rugged environments.
