BBK Varitune Cat-Back Exhaust W/ Resonator Delete Mustang Coupe GT 2015-2017

Switch between a mellow pitch and one that’s 8-10 decibels louder than stock on the fly in your 2015-2017 Coupe GT Mustang using BBK’s Varitune Cat-Back Exhaust System (30065)! 5.0L engines pair excellently with this system thanks to the Varitune mufflers inside. With just a wrench twist, you can set the adjustable screw in their internal power valves to the closed or open position. When closed, it uses all three muffler chambers while the open position mimics straight-through mufflers by using one. Sound is made even more aggressive by the resonator delete x-pipe. With the rest of the system’s 2-3/4” mandrel bent tubing, it yields the best flow possible!
