Product Details

The MBRP S5248409 Armor Plus Series cat-back exhaust system delivers enhanced performance and an aggressive exhaust tone for 2011-2014 Ford F-150 trucks equipped with the 3.5L V6 EcoBoost engine. Constructed from corrosion-resistant T409 stainless steel, this 4-inch diameter exhaust system features mandrel-bent tubing that maximizes exhaust flow and eliminates restrictive kinks found in crush-bent systems.

Key Features:

  • T409 stainless steel construction for corrosion resistance and durability
  • 4-inch mandrel-bent tubing provides up to 70% flow increase over stock
  • Single side exit configuration with 5-inch polished stainless tip
  • Bolt-on installation with all necessary hardware included
  • Enhanced exhaust note without excessive drone
  • Backed by MBRP's lifetime warranty

Mandrel bending technology ensures smooth, constant-diameter bends throughout the exhaust path, allowing exhaust gases to exit more efficiently. This improved flow reduces backpressure, which can result in modest horsepower and torque gains while improving throttle response. The T409 stainless steel material offers excellent value and rust resistance for most climates, though exposure to heavy road salt and harsh winter conditions may accelerate surface corrosion over time.

The system includes a mirror-polished 5-inch diameter tip that adds a custom appearance to complement the performance upgrade. Installation is straightforward using factory mounting locations and the included hardware, making this an ideal upgrade for truck enthusiasts seeking improved sound and performance.

Nice website

very fast and easy.

Best price on Bilstein Shocks on the web. Ordered shocks on 4/25 and they shipped same day. FedEx has delivery date of 4/28. Received confirmation email after order was complete. Website had product inventory next to part number was very helpful. Other websites don't have this and this patprticular part is on back order for 30 + days. Will update once shipment received.

I ordered a lower control arm for my 2002 MERCEDES S500.<br>The order was shipped fast and the price was way lower than any of the competitors.I highly recommend AUTOPLICITY.COM

Really pleased with the service I had. They had the best price I could find, and they shipped quickly. Highly satisfied
