Description
The ROCK BASHER 2.5" to 3" Cat-Back Exhaust System is a rugged, purpose-built performance upgrade designed specifically for 2007–2018 Jeep Wrangler JK 4-Door models. Engineered for off-road enthusiasts who demand increased ground clearance without sacrificing power or sound quality, this system delivers improved exhaust flow, enhanced durability, and a bold performance tone.
Constructed from 2.5-inch to 3-inch mandrel-bent 409 stainless steel tubing, the ROCK BASHER cat-back exhaust significantly outflows the restrictive factory system to help unlock additional horsepower and torque. Smooth mandrel bends reduce turbulence, improving throttle response and overall engine efficiency while maintaining long-term corrosion resistance.
A defining feature of this system is its unique pre-axle turn-down tip, which exits under the vehicle before the rear axle. This design dramatically increases clearance and protects the exhaust from rocks, ledges, and trail obstacles—eliminating the risk of crushed or damaged exhaust tips during aggressive off-road driving.
Sound is tuned through an 18-inch free-flowing stainless steel muffler, engineered to absorb harsh, high-frequency tones while producing a deep, powerful exhaust note. The result is an aggressive yet refined sound profile that enhances driving enjoyment without excessive harshness.
The system utilizes factory mounting locations and OE-style bayonet hangers to ensure a secure, vibration-resistant fit under extreme heat and off-road conditions. Each exhaust is 100% hand MIG-welded for maximum strength and longevity, and includes high-quality stainless steel clamps and hardware for a leak-free 360-degree seal.
Designed as a true bolt-on upgrade, the ROCK BASHER cat-back exhaust installs quickly with no cutting or modifications required—making it an ideal solution for Jeep owners seeking trail-ready durability and performance.
