BBK Varitune Axle-Back Exhaust System Mustang Coupe GT 5.0L 2015-2017

From an adjustable pitch to 8-10 decibels louder than stock, BBK’s Varitune Axle-Back Exhaust System is what your 2015-2017 Coupe GT Mustang craves (41115). This system is perfect for 5.0L engines thanks to its one-to-three chamber mufflers. Unique internal power valves with adjustable screws set them apart, offering two sounds via two positions. While the closed position uses all three chambers for a mellow tone, the open one mimics the hoarse pitch of straight-through mufflers. 2-3/4” tubing maximizes the system’s flow, precisely mandrel bent from 304 stainless steel. Plus, since it’s designed as a direct fit, it easily bolts on.
