2010-2012 Flex EcoBoost "Eco-Flow" Axle Back Exhaust

The MRT team of engineers went to work and the elusive system has finally arrived: Meet the Eco-Flow series of Axle-Back Exhausts. The MRT Eco-Flow Axle-Back Exhaust for the 2010-2012 Ford Flex EcoBoost has a unique turbo performance sound. The Eco-Flow exhaust announces its presence without being obnoxious or overly aggressive. So when your on that family trip the kids will still be able to hear their movie! The free-flowing MRT Eco-Flow muffler provides a pleasing exhaust note, with minimal resonance.

MRT Performance manufactures our Eco-Flow Axle-Back Exhaust from the highest grade 304 Stainless Steel. This premium material is light-weight, supremely durable and won't rust. Installation of the exhaust is simple and drill-free. The MRT Eco-Flow Axle-Back clamps-on directly in place of the factory axle-back. 3.5 inch polished Stainless Steel exhaust tips come pre-welded to the axle-back and are included with purchase. As always, MRT Exhausts are made in America, by MRT Performance.

It has been reported (by independent testing) that the Eco-Flow Axle Back increases Horsepower, Torque and Fuel Economy over the stock system.
