Construction & Design

The Installer Series Cat-Back Exhaust is crafted from heavy-duty aluminized steel, chosen for its excellent corrosion resistance and durability, especially suited for dry climates. This material offers a cost-effective alternative to stainless steel while maintaining long-lasting performance. The mandrel bent tubing preserves a consistent diameter through bends, preventing flow restrictions and maximizing exhaust efficiency.

The system features a 3.75-inch oval stainless steel tip that enhances the Wrangler’s rugged aesthetic while resisting the elements better than painted tips. Every component is engineered for precise fitment using OEM hangers, ensuring a secure, factory-style installation that maintains the vehicle’s structural integrity without the need for cutting or welding.

Performance & Sound

This cat-back exhaust system enhances engine breathing by increasing exhaust flow, which can lead to improved throttle response and a modest boost in horsepower and torque. The muffler is tuned to produce a mellow yet aggressive exhaust note that is distinctive without being overly loud or intrusive during highway cruising. This balanced sound profile makes it suitable for both everyday driving and spirited off-road use, providing a satisfying auditory experience that complements the Jeep’s adventurous spirit.
