Product Description

The Gibson 17303-B Black Elite Cat-Back Dual Split Exhaust System is a performance-designed upgrade tailored specifically for **2007-2017 Jeep Wrangler JK** models equipped with the 3.8 L or 3.6 L V6 engines. This cat-back exhaust replaces your factory system from the catalytic converter back with mandrel-bent 2.50" aluminized steel piping and a proven SuperFlow™ muffler, which together reduce backpressure and support improved engine efficiency. The chambered, baffled muffler is engineered to deliver an **aggressive yet controlled exhaust note** that's deeper and richer than stock but avoids excessive cabin drone. 

Part of Gibson's Black Elite™ series, the 17303-B features dual rear **4.00" black ceramic coated stainless tips** that not only look striking but are also heat-resistant and corrosion-resilient. The split dual outlet design helps balance exhaust flow and tone while preserving ground clearance and enhancing both style and performance. Installation is straightforward with the supplied factory-style hangers and clamps - **no welding required** - making this system ideal for enthusiasts who want a strong visual and sonic upgrade without a complex install.

Fitment for the Gibson 17303-B is confirmed for **Jeep Wrangler JK models from 2007 through 2017** with 3.8 L V6 and later 3.6 L V6 engines. Whether you're hitting the trails, towing loads, or cruising the highway, this exhaust system adds a deeper exhaust tone, improved flow characteristics, and enhanced backing-off sound that elevates the driving experience over the factory setup. Backed by Gibson's **lifetime limited warranty**, it's a durable performance choice for Jeep Wrangler owners seeking both style and function.
