Description
ATLAS 4” Aluminized Steel Cat-Back Exhaust System with Polished Tip
Upgrade your truck’s performance, sound, and appearance with the ATLAS 4” Cat-Back Exhaust System by aFe POWER. Designed for optimal exhaust flow and long-term durability, this system features 100% MIG-welded, 4” mandrel-bent aluminized steel tubing to significantly improve horsepower, torque, and throttle response.
The system utilizes a high-flow single-in/dual-out stainless steel muffler that reduces backpressure while absorbing high-pitched exhaust tones. This results in a deep, aggressive exhaust note that enhances driving excitement without excessive drone.
Engineered for a precise OE-style fit, the ATLAS cat-back exhaust uses factory mounting locations, bayonet-style hangers, and heavy-duty band clamps to ensure a secure, leak-free installation that maintains proper alignment under extreme heat and vibration.
