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.

Stainless Steel Construction. Constructed from highest quality Stainless 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.

    BBK Varitune Axle-Back Exhaust

    The 2 things I think about when looking at adding or changing parts to my Mustang are. 1. Is it worth the price and 2. will it improve performance and or looks. These Varitunes did both, it was not cheap at $519.99. (I Paid $509.99 I found a $15.00 coupon) The installation: The only problem I had was getting the clamps tight enough on the passenger side. I really had to put some muscle into it to get them tight enough not to move. I really like the looks of the tips, just what I wanted NOT FACTORY, The Sound is great. opened or closed. BUY THESE.!!!!

    The BBK varitune mufflers

    I have yet to have them installed but like every thing else BBK makes i have absolute faith in them and i believe they will definitely enhance my horse power as well as the sound factor also ilike the idea of varitune because with that I can use it on the street without any worries and then if and when i take it to the track i can make them almost a straight thru pipe which should enhance and increase the rear wheel HP by a bit yes I would recommend them for any car for the factors i wrote about them above

    great sound, and adjustability

    I recently bought my first Mustang, a 2006 GT. When I got it, it already had after market mufflers, but the stock mufflers were also included. Although I liked the sound of the car, the mufflers were just too loud for me so I installed the stock mufflers. I liked that they were quiet, but I wanted a better sound, something in between the two sets of mufflers that I had. I narrowed down my choices to three different models and decided to go with the Varitune mufflers since they offered adjustability. I am happy with the sound. They are louder and sound better than stock without being crazy loud. They give the car a nice rumble but are not overly loud when at cruising speed. At this point, I have not yet even opened them up, but I will most likely do this when I take the car to the track to get a little more power.
