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 least resistance, acting 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 review

    Installation took just under 2 hours from start to finish. Installed using jackstands no lift. Relatively easy install... had some issues with rusted hanger bolts. Fit-up was good, tips look great. Only thing i have a slight issue with... its pretty darn loud on highway driving. Especially while running around 2k on the tach. But i just close the damper and its fine for long drives. Overall, I'm very happy with the exhaust. Would recommend to other buyers.

    Varitune Power

    These mufflers were installed by Muffler Man for $100.00, they had never seen anything like them. I had them put the mufflers on the one chamber straight -through "open" position, I will probably never change them! These have an aggressive "grumble" at idle and a smooth "throaty" increase as you move through the gears (manual). They sound aggressive but not over the top, my mustang now sounds like it looks! The polished tips are wider but fit right in the same hole as the stock muffler tips, and they look awesome, like they should! A comfort knowing that if I wanted to sell my mustang I can switch to the mellow sounding three chamber configuration with an adjustable wrench!

    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.

    Baritone by BBK

    Fantastic and ingenious system. Sounds great and is easy to install. The SS version is the way to go in the wet, great NW and any other such states where rain is a factor to consider re rust. Thanks again for the great service AM!

    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

    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.!!!!

    Great product made in the USA

    I am 60 years old and installed these in a couple of hours with out lifting the vehicle. Don't even start this job if you don't have an impact wrench!! unless you want to take it to a muffler shop to tighten the clamps all the way when your done. You can pick up an electric impact wrench at Harbor Freight for $39.00 with coupon that you can download. These sound great open or closed however if you are going on a long trip you might want to close them. I didn't have to loosen the mid pipes because i removed the brackets a little hard to get at but doable if you have the right tools (ratcheting box wrench's 13MM and 15MM). Fit great and sound great and look awesome. I highly recommend these.
