aFe MACHForce XP Exhausts Cat-Back Polished Tips 09-17 GM Silverado 1500 4.3/5.3L RegCab SB/LB

aFe introduces the MACH Force XP exhaust system for the BMW M5 F10 twin-turbo. In recent testing this system produced 18 horsepower and 30 lbs. x ft. of torque. This unique exhaust system is constructed from TIG-welded, 3 in. mandrel bent 304 stainless steel and uses quad, high-flow mufflers. This system was designed and engineered by tuning the perfect tube lengths, ultimately maximizing performance across the power band while maintaining a great tone. Also included is an X-pipe balance tube which equalizes and evenly distributes exhaust pulses for increased flow and minimizing exhaust drone. To finish off this system, aFe uses four 4 in. carbon fiber tips with 303 stainless steel machined finish inserts. This exhaust uses all factory hanger locations f or a hassle-free installation. No modifications necessary. All aFe exhaust systems are manufactured in our Corona, California manufacturing facility.
