    "The Boom Tube" This MAC Performance Axle-Back System eliminates the restrictive stock mufflers entirely from your Mustang, to uncork the exhaust flow reducing back pressure for an increase in power and sound.

    Resonator Tips. Often imitated but never duplicated, the MAC Boom Tube Axle-back Exhaust uses uniquely designed dual wall resonator tips that feature perforated baffles to provide a loud throaty exhaust note without the irritating popping of the imitators.

    Durable Steel Construction. Constructed from 2.5" diameter mandrel-bent 304 stainless steel tubing, the Boom Tube axle-back system features polished 4" angle cut stainless steel dual wall tips for impressive muscle car styling and sound.

    Application. The MAC "Boom Tube" Axle-Back exhaust system is designed to fit the 2005-2010 GT, 2008-2009 Bullitt, and 2007-2010 Shelby GT500 Mustangs for impressive looks and sound. This axle-back is made to be a direct bolt on to the stock location without any modifications required.

    Please Note. MAC Performance does not make any claims that their Boom Tube exhaust will meet any federal or local noise regulations or laws. Please check your local and state ordnances for installation and usage regulations.

    Technical Note: Americanmuscle recommends adding the 2005+ Mustang 304 Stainless Steel Exhaust Hanger Kit from the drop down option above, to provide more strength, stability and a cleaner installed appearance. If you have a 2007 Mustang you may need the kit for correct installation.

    v6 dual exhaust? I have a 2008 grabber orange v6 with a single boom tube on it and I love the sound, so Ive decided to get duals. So I guess my question is can I justbuy the driver side one from AM instead of buying the axle back set?

    • Unfortunately, we don't have the dual axle-backs sold individually for each side. MAC direct might be able to work something out with you, but we only carry them as a pair.

    Even though these are for GT mustangs, would they fit on an '06 mustang V6?

    • The MAC Boom Tube Axle-Back Exhaust will not fit a V6 Mustang without additional modifications such as either a GT bumper, or trimming the V6 bumper, and GT style hangers, over axle pipes, and mid pipes.

      DEEEEEEP GROWL!

      I have these installed on my 2008 GT. They sound amazing alone! I bought these with a Pypes H-Pipe. Along with a pair of Dynomax Bullets. I have not installed the hpipe or bullets yet. I was looking for a deep note and nice idle. These are it, BOOM TUBE! I can't imagine how this beast will sound with everything on it. 10/10

      Mac boom tubes review

      I received the exhaust fairly quick and had no problems with the shipping. When I opened up the box the exhaust was packaged very well and was wrapped in bubble wrap. After taking off my old stock axle back I started to install the boom tubes. Install was very straight forward and I didn’t need instructions. (Good thing because there was no instructions packed with the boom tubes) the exhaust lined up well with the back bumper very well and took me less than an hour and a half to do. The tone is amazing, very deep and low rumble. Loud at WOT and quiet when you need to be. On a loud scale of 1-10 this would be a 7.5. It can be a little louder but 100 a good quality product. I bought these for a 2007 Mustang gt California special.

      Great exhaust!

      I bought these mufflers looking for something that was as loud as straight pipes but without the annoying drone and obnoxiousness that comes with it. These mufflers absolutely were everything I was looking for. In low gears the car screams when you get on it but when your cruising down the road on a trip they sound no louder than stock. When you fire the car up it's noticeably deeper and more alive than stock. Plus the massive tip on this thing sets the rear end of the car off. As far as install goes they give you everything you need and it all lined up like it was supposed to. I'm not a mechanic by any means but the install walkthrough and videos that AM supplies make it like a walk in the park. A little muscle to get the old equipment off and pretty well go in reverse when you put the new ones on. Took me about an hr to hr an a half to get it all done. Would be easier if you jack the rear of the car up to move better but I didn't and still got it done. If your looking for a classic aggressive tone, Here it is!!

      Unbelievable how awesome they sound. I've used other axle Backs from comprable companies but honestly could not get the right sound. Mac boom did it

      Wasn't looking for something deafening just an aggressive sound. This was perfect, there's no drone and people have certainly been turning their heads. Better deal than name brands with the same quality

      Great Axle-Backs

      Super easy install, fit like a glove with factory hangers. They sound great, not offensively loud but still give it a deeper, more aggressive tone with limited drone.

      Perfect!!!

      I've run many exhaust systems on a few different vehices, and I definitely like these the best. Absolutely NO highway drone! But when leaning into it you are CLEARLY heard. This axle back has a very nice deep growly tone to it, not raspy at all, and holds just enough back pressure with the ribbed tips. Stock exhaust volume is around 4/10 for loudness, I'd rate the boom tube's around 7.5/10. Definite recommend for someone wanting that awesome loud growl these 4.6's can make when opened up.

      Makes you want to drive

      I'm very happy with my macs! Coupled with an off road x pipe they didn't have any rasp just a nice growl at low rpm and a high pitched iconic mustang tone at 3k rpm and up. Not to loud just right

      THE MACS!!!!

      Macs are way louder than stock But not annoying at all About 2 hour install on stock v8 I reccomend getting some new exhaust tape, to place under the clamps , to stop any air leak where the mid pipe and axle back connect.

      MAC DADDY!!!

      My first question is why aren't these rated 5 stars!!??? These Mac booms are the best sounding axle back mufflers out there! Brings a deep clean rumble. Very easy to install. I have heard all kinds of exhaust setups for the S197 and these are the best sounding. I get so many compliments and people smile when they hear my exhaust. Not a lot of drone like most mufflers. Quit reading these reviews and purchase now! You won't regret it!!

      Wow. These sound amazing

      These mac boom tubes complete my exhaust setup exactly what I wanted. My setup is Mac Long tube headers, Pypes Xpipe and boom tubes. These sound wicked get a lot of good looks. Some people get pd off tho and roll up their window... Very minimal drone at cruising speeds but when you open it up sounds amazing !!!
