Description
Adjustable Sound. This BBK Mustang Axle-Back Exhaust system features BBK's patented tunable Varitune performance mufflers that allow you to change from a mellow three chamber exhaust sound to a rich throaty straight-through exhaust note with just a twist of a wrench, for a 8 to 10 decibel sound level difference!

How It Works. BBK Varitune performance mufflers utilize an internal "Adjustable Power Valve". When in the closed position the valve blocks the exhaust flow forcing it through all three chambers of the muffler for a classic mellow sound. When in the open position the valve "uncorks" the exhaust flow allowing it to take the path of lease resistance to act more like a straight-through muffler for a rich throaty exhaust note. This unique design is perfect for personalizing the power and sound levels of your Mustang to suit your own specific needs.

Aluminized Steel Construction.
Constructed from highest quality Aluminized Steel available, this BBK Performance Axle-Back exhaust system features Varitune chambered mufflers that end with 4" polished 304 stainless tips for impressive looks and sound. The tips exit in the stock locations so no modifications are required to the rear bumper cover.

Application. This BBK Varitune Axle-Back Exhaust is designed as a direct fit bolt-on upgrade for the 2005-2010 GT and Bullitt Mustangs equipped with the 4.6L 24V SOHC Modular V8 Engine.

  • As in do you need to retune the engine? No, mufflers don't have that much of an impact on the cars electronics.

    So easy to go back and forth between 3 stage and 1 stage ( in my opinion keep it in 1 stage all the time and try not to obnoxious to your neighbors ) . Didn't realize my car could sound so good with so little effort and little cost . I've told everybody who'd listen about this product and who sells it .

    I just did not realize

    July 23, 2014

    These varitune mufflers are phenomenal! Not only can I open them up for a nice full sound, I can tune out the drone! I had the American Thunder Outlaw Series on the car before and it was loud all the time. I needed something to quiet the car down but still give me that nice rumbling sound I crave. These work like a champ! Install was easy enough. Made for adjusting the bracket and getting the exhaust to sit right a breeze. One tip had some burs on it the kept it from going on easy buy it was a quick fix with a file. Overall th we yet great for that everyday drive and when you want to thrash it around a bit. Highly recommended!
