Description
Aggressive Throaty Sound. Add a throatier muscular exhaust note to your 4.6L GT and improve the exhaust flow at the same time with a MAC Performance Axle-Back exhaust system from AmericanMuscle.

Flow Path Mufflers. MAC Flow Path Chambered Mufflers feature a patented multi passage design, following Helmholtz's Theory of Tone, to produce a muffler that effectively flows exiting exhaust gases all while maintaining a desirable tone. With no packing that can burn out, Flow Path Mufflers will sound the same mile after mile, year after year.

High Quality Construction. Constructed from durable 2.5" stainless steel tubing for strength and corrosion resistance this MAC Performance axle back features two "Flow Path" chambered mufflers that end with massive 4" diameter polished stainless steel tips for classic muscle car looks and sound.

Application. This MAC Performance Axle-Back exhaust system is specifically designed to fit the 2005 to 2010 GT and Bullitt Mustangs with the 4.6L 3 valve V8 engine.

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.

Fitment: 2005 2006 2007 2008 2009 2010 Details

Ugh, YES.

This is by far my favorite exhaust I have heard on any 4.6L mustang GT. VERY VERY deep, at a nice loud (but not too loud) volume. It does have a pretty bad drone, but I don't mind it at all!!

    08 Gt/Cs Mac axle back exhaust

    Did hours apon hours of research on which mufflers to get, after finally making a decision I certainly made the correct one. The sound is a deeper than stock setup and makes my gt sound like a v8 should sound. Highly recommend these mufflers!

    Great Sound

    The install is very easy. We had to loosen up the pipes about mid ways up to get a little more play in order to set them right because the hangers are already mounted on the muffler. The sound is great! It's not as loud as some but has a good low tone.I had a little bit of a drone at first. I experienced a slight rattle sound for about a month after the install around 1700 rpms but that went away fairly quickly. Overall they are great! I would definitely recommend them. Plus they are stainless steel so they don't rust and always look sharp. The only reason I rate them 4 out of 5 is because I somewhat wish they were a bit louder, otherwise they are a 5.

    Now This is the way a Mustang GT is Supposed to Sound!

    Switching from stock to the MAC axelback exhaust on my 2005 Mustang GT was a no brainer. Stock mufflers are fine for most, but a true muscle car enthusiast knows that your car has to sound just right. These MAC mufflers deliver a serious growl, with a true performance note under throttle. The 4 inch tailpipes look perfect and improve the look over stock significantly. Install was no problem, even for a backyard mechanic like myself. As I expected from my research, there is an interior drone present at low RPM, (about 1800-2000) but it is a small price to pay, considering every other factor. Go for it, and you'll never look back.

    The install was not difficult despite not receiving instructions. The difficult part was having to remove the index lug for a proper fit and the supplied band clips were not strong enough so I had to replace them with U-bolt brackets. Overall the install took only 2 hours. The deep aggressive sound is perfect. I rated this item as a 4 only because of the band clips supplied needed to be replaced and not receivivng instructions.

    Good product

    Super easy to install took all of an hour to do with me and a buddy. The fit meant isn't exactly the way I wanted to it to look like but I managed to make some adjustments and it looks awesome. The sound is very aggressive you can hear me way before you can see me and all my friends know when I'm coming. The only bad thing is I've noticed surface rust on them already but I just used some chrome polish and they're as good as new. Also if you don't like loud mufflers these are not what you're looking for but if you like that high performance aggressive sound this my friends is for you. Overall I'm very satisfied with these mufflers.

    great sound

    This gave me the exact sound I was looking for. I had flowmasters on before and it sounded like terrible compared to this. It took less than an hour to install. I recommend this to anybody with an 05-09 GT

    Mac Axlebacks

    I was torn between these Macs and Flowmaster's American Thunder Classic. I chose Mac, and I love them. Installation was smooth and easy, and they gave exactly the sound I want. It is deeper and louder than stock without being too much. Plus, the polished 4" slash cut tips look great. I couldn't be happier.
