AFE | 49-03041NM | Atlas 4" Aluminized Steel Cat-Back Exhaust System Fits 2011-2014 Ford F150 3.5L EcoBoost (No Muffler/No Tip)
Aggressive, Large System with Huge Performance Potential
aFe's ATLAS series of performance cat-back exhaust systems are designed from the ground up to give your powerful F150 EcoBoost a massive sound at a nice, low price point. The aFe ATLAS exhaust kit is out-and-out aggressive and gives you and your truck the bare bones ingredients for getting improved horsepower, torque, and sound while keeping its price low. Despite its large tubing, the aFe ATLAS kit is designed to install right in place of the factory cat-back exhaust system on trucks with 145", 157", or 163" wheelbases.
Large-Diameter Tubing with High-Flow Muffler
aFe builds their EcoBoost ATLAS cat-back exhaust system out of 4" mandrel-bent tubing that provides a larger outlet and smoother flow path than your truck's factory crimped exhaust system, which reduces back pressure and restrictions for excellent performance gains. The tubing is all made out of aluminized steel which keeps the price of the kit down while making it suitable for milder climates.
This cat-back exhaust kit deletes your factory resonator for a more aggressive tone.
F150 Wheelbase fitment: This kit will only fit F150 EcoBoosts with 145", 157", and 163" wheelbases
