BBK (41015): 2011-2014 Mustang GT 5.0 Varitune Stainless Steel Axle Back Exhaust Kit

These BBK Varitune axle back exhaust kits offer great, tunable sound in conjunction with BBK’s patented adjustable power valve. That’s right: These BBK systems come with two patented Varitune performance mufflers engineered with  high-flow, direct-fit tubing and hardware for a true bolt-on installation. Also included is a pair of new 4″ polished, high-flow internal chamber exhaust tips for maximum looks and performance. Tune your BBK Varitune system with a simple adjustable wrench on the muffler itself: Turn it all the way out for maximum horsepower and sound at the track or car show, or down for a milder sound for a family road trip. BBK Varitune exhaust kits are great fun and offer enthusiasts real-world performance gains.
