An MBRP performance exhaust system is the starting point to getting the most from your cold air intakes, tuners and other bolt-ons. Combined with an aftermarket downpipe, this system will not only sound amazing, but also show great power gains due to drastically improved flow capacity. Furthering those power gains is a high-flow Y-Pipe and large 3” mandrel-bent aluminized steel piping all capped off with stealthy 4-1/2” black tips.

Installation is a walk in the park with a lift and not too bad with a jack and jack stands, take into consideration it’s a 100% bolt-on installation with basic hand tools. This exhaust system spent numerous hours on the dyno and hundreds of miles on the street and track to guarantee the best performance imaginable. MBRP's cat-back system was engineered to maximize exhaust flow and in turn minimizes exhaust temperatures.

The new 2.3L EcoBoost engine has just made its introduction into the Mustang, but already has been proven to make huge amounts of power, but the exhaust note just isn’t there to back up the potential that rest beneath your hood. This cat-back system from MBRP will take your EcoBoost S550 to the next level without making your ears ring. The exhaust notes of this particular system are subtle and civilized during normal driving, but quite aggressive when your gas pedal hits the floor.
