BBK has changed the muffler game completely, with their all new Varitune Mufflers that allow you to fully adjust the sound levels and horsepower output from your Mustang's exhaust with the simple turn of a wrench!
BBK's Varitune Mufflers are designed and constructed in America using high-quality heavy-gauge Aluminized Seel or long-lasting heavy-gauge Stainless Steel. They are available in three different sizes, 2-1/2", 2-3/4" and 3" with an inlet and outlet in an offset configuration to fit most OE and aftermarket 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003 and 2004 Mustang exhaust systems.
Don't like being committed to just one decibel level emitted from your exhaust? These first of their kind, patented, Varitune Mufflers are a fully customizable performance muffler featuring an adjustable chamber valve built into the muffler, allowing you to change the resistance or ease of exhaust flow and also exhaust pitch with the turn of a wrench. BBK's Varitune Mufflers provide the capability to switch from a one-chamber to a three-chamber exhaust and modify the sound levels by up to 8 decibels across the adjustment range while also adjusting the power levels.
So if the classic, melodious and smooth rumble is what you need for a quiet drive or if the throaty and full, earthshaking growl is what you're looking for, you now have the opportunity to choose which sound you prefer on the fly!
