      Review & Installation Video

      I’m Justin with, and I’m going to be breaking down Pypes Violator Axle-back exhaust for the 2005-2010 Mustang GT. Even though the Violator uses what appears to be a traditional chambered muffler design, much like your factory exhaust or even the Magnaflow street, but instead of this muffler being filled with sound baffles, which can actually keep your sound levels down, the Violator from Pypes actually includes some sound deflectors into the muffler design, which give you a very aggressive exhaust note. Those rude sounding mufflers are constructed from thick 409 grade stainless steel, and exit out of these dual 4” polished tips, which feature a very cool rolled edge and slashed cut for a unique, quality look. Since the Violator bolts into the stock location without any modification, getting everything installed should only take you about an hour using a basic socket set. Now let’s hear how Pypes Violator series axle-back sounds compared to our factory exhaust.

      Aggressive Sound.

      Quality Construction, OEM Fit.
      This Axle-Back system from Pypes is constructed from high quality 409 Stainless Steel and features 4" rolled edge, slash cut, polished 304 stainless tips that exit in the stock location for aggressive muscle car looks.

      Application. The Pypes Violator Axle-Back is designed to fit the 2005-2010 GT, 2008-2009 Bullitt and 2007-2010 Shelby GT500 Mustangs.

      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.

        Good product

        I’ve had the Pypes Violators on my 2006 GT for two years now and they still sound great. Obviously they’re not very loud but I knew that when I purchased them. The sound is deep and aggressive. After two years the polished tips still look good and I’m still happy with the purchase. Perhaps in a few years I’ll pony up some more money and get something louder but I don’t regret this purchase.

        Pypes Violator

        These axels backs definitely live up to their name, they have a deep tone around 2000rpm are loud but not excessively obnoxious. Not much drone, in the higher RPMs. Came in packaged perfectly, nothing damaged, clean and shiny. Installed myself in roughly 90 minutes, just laying out in the driveway. Hardest part was removing the stock mufflers off at the clamp. Looking forward to match them up with some long tubes and new cams for a more aggressive roar.

        Well ladys and gentlemen. I have a 2007 GT with Kooks LTH and Cats and my flowmaster American Thunder mufflers finally came apart after 11 years. So since AM doesn't sell flowmaster for our gen anymore, I went to Pypes Violators. I went from having a car that sounded like a beast to a car that sounds like a kitty cat and I cant get my money back. Not happy at all. The fit was good but the note just isn't there, not when your coming from flows. I guess I got violated. They need to change the name hushpuppys.

        Good sound

        They were easy to install and while they are definitely a bit louder than stock, the best improvement is the actual note that's made. They do drone but they are good overall.

        Great Sound

        They really sound great and look even better they weren't that expensive and since they are "Pypes" brand they'll be an asset once I go to sell.

      5 Top Rated Questions

      How bad does it drone? I have an 06 GT with really quiet flowmasters on it and I was wondering how these compare to mine in volume and restricions. Mine are almost the same as stock, just a little louder. And I was wondering how bad do they drone at an idle and at highway speeds?

      • I have them on my 2005 GT, and when I got them I didnt realize I had a bad throttle body and they had terrible drone, but that was because I had a throttle body sensor failure. I got my throttle body fixed and I no longer have any drone! They may have some at first, but once they get worked in a little it will subside. Overall, I love their sound over any other pipes on the market!

      Do I need the extra bracket kit for this install?

      • The Pypes Violator Axle-Back Exhaust would not require the additional exhaust hangers for installation on 2005-2010 GT and GT500's.

      I really like the sound of these for my next mod but I'm not exited about the idea of loosing low end. How much low end torque is lost on a stock car with CAI/tune?

      • The amount of low end you will lose will not even be noticeable. There is not enough back pressure built up by the rear mufflers to make a big difference in power. I think this will be a great mod for your Mustang!

      will this reduce backpressure/popping sound? I am using Pypes Pype Bombs and recently got an off road pipe installed and it is just WAY too loud and has that obnoxious popping sound, will this reduce that but still make it sound mean and loud

      • Yup , shure will. The pype bomb design is one that mimics the classic design of a glass pack. And that design is one that gives that popin sound. The chambered style mufflers like this one give a much deeper tone.
