Identified under part number #19651, the cat-back exhaust from the xMOD series isn’t exactly cheap. MagnaFlow is asking $3,999 for it, which is a heck of a lot of moolah. Still, the F-150 Raptor R is a lot of money as well, costing more than $100,000 from the outset.
The Oceanside-based company mentions dyno-proven gains on its website, yet fails to actually tell prospective customers how big those gains are. As a brief refresher, Ford's truck belts out 700 horsepower at 6,650 revolutions per minute and 640 pound-feet (868 Nm) at 4,250 revolutions per minute. Its Predator is an idea different from that of the Shelby GT500, and its torque-converter automatic is hugely different from the dual-clutch transmission of the 760-horsepower fastback.
Configurable from aggressive to very aggressive, MagnaFlow's exhaust retains the functionality of the factory exhaust valves. Main piping comprises 3-inch mandrel bent pipes that replace the stock exhaust from the catalytic converter back. Customers have a choice between 11-inch No Drone Technology mufflers or 11-inch xTreme Delete straight pipes. Further back, you'll find the aforementioned valves joined by an X-pipe.
The xMOD exhaust system wouldn't be complete without dual outlets, namely 5.0-inch black tips with rolled edges. Better still, this aftermarket solution further includes front pipes that can replace the factory-issue resonated pipes. MagnaFlow highlights that its xTreme Delete straight-through modules are meant for track and off-road use. Said modules may not comply with local noise regulations for public road driving.
Manufactured using CNC machining, #19651 is made from stainless steel fore to aft. Boasting a one-year limited construction warranty and a lifetime limited warranty, said exhaust fits only the F-150 Raptor R.
Everyone knows that stainless steel can rust, but fret not. MagnaFlow uses 409-grade stainless, which provides good corrosion and oxidation resistance. However, bear in mind that type 304 and type 304L have better corrosion resistance. Type 409, on the other hand, was developed specifically for automotive exhausts.
It's also worth remembering that 304 grades develop a brass-like look when exposed to high heat, which exhausts are on a daily basis. Oh, and by the way, 409 has excellent thermal and strength properties.
