RELIABILITY BACKED FOR A LIFETIME - ARMOR PLUS Series exhaust systems are crafted from corrosion-resistant T409 Stainless Steel - a value-oriented material designed to protect from penetrating rust and will stand up to almost anything you can throw at it. T409 Stainless Steel tubing is easy to clean. If you’re looking for a performance exhaust system with a Lifetime Warranty, this is probably the one for you. If you don’t find yourself faced with lots of precipitation and salt, this is all you’re ever going to need. All of the tubing is mandrel bent for maximum exhaust flow. Mandrel bending ensures no rippling in the bends. The end result is that it gives you more fresh air inside your engine’s cylinders, allowing it to produce more power and improve vehicle performance and longevity. It's important to note that T409 Stainless Steel is resistant to penetrating rust but winter conditions, heavy salt air, and road treatments might accelerate the corrosion process, these conditions are not covered by MBRP's manufacturer warranty unless the part or system fails completely. When it comes to a performance exhaust system, choose the MBRP ARMOR PLUS Series for a reliable option backed for a lifetime.

Upgrade the exhaust performance and sound of your Ford Fiesta ST with the MBRP Armor Plus Cat-Back Exhaust System. Designed for 2014–2019 Ford Fiesta ST models equipped with the 1.6L EcoBoost engine, this system uses 3-inch mandrel-bent tubing to promote efficient exhaust flow. The dual-outlet configuration and included 3.5-inch outside-diameter stainless steel tip deliver a clean, performance-oriented appearance while maintaining a mellow exhaust note.

Constructed from corrosion-resistant T409 stainless steel, the MBRP Armor Plus system is designed to withstand everyday driving conditions and resist penetrating rust. T409 stainless steel is easy to clean and provides a practical balance of durability, performance, and value. However, exposure to heavy road salt, winter treatments, or salty coastal air may accelerate corrosion and is subject to MBRP warranty limitations unless the system or part fails completely.

The bolt-on design utilizes factory exhaust hangers for a straightforward installation and includes the muffler, front extension pipe, extension pipe, tailpipe, hardware, and stainless steel tip. Mandrel bends help maintain consistent tubing diameter through the bends, supporting improved throttle response, torque, horsepower, and lower exhaust gas temperatures. MBRP backs this Armor Plus exhaust system with a limited lifetime warranty. This product may require emissions-related acknowledgment where applicable and is not identified as California Air Resources Board approved.
