Product Description

The Gibson 17303 is a dual split axle-back exhaust system engineered for 2007-2017 Jeep Wrangler JK and Wrangler Unlimited JK models with either the 3.8L V6 or 3.6L V6. Gibson markets this system as a bolt-on performance upgrade that improves exhaust flow, reduces backpressure, and helps increase horsepower and torque. The dual split rear exit design routes the exhaust behind each rear tire, which helps maintain ground clearance for off-road use while giving the Jeep a more aggressive finished look.

This system uses 2.50-inch mandrel-bent aluminized steel tubing and a baffled/chambered muffler to produce a deeper, more aggressive exhaust note with controlled cabin drone. It installs using factory-style hangers and clamps with no welding or cutting required. This is not a lift or lowering product, so no front/rear height change applies. Fitment is confirmed by Gibson for 2007-2011 3.8L JK models and 2012-2017 3.6L JK models. Some retailer listings extend coverage to 2018 JK/JKU, but Gibson's official 17303 listing specifies 2007-2017, so 2018 coverage is not confirmed for this listing.
