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.
