    Will these pass emissions/smog check in California


    Will this work with a v6 conversion kit if I have custom hanger set


    • The Pypes Muffler-Delete Axle-Back Exhaust will not work on the V6 models unless you have the dual conversion set up already.

    Need the Driver's Side pipe from CAT Back to Tip only, is this possible ? The previous owner of these muffler deletes modified the pipe to accommodate a fuel cell, which I do not have and it doesn't fit without cutting and welding, would rather have the original piece, minus the tip. Let me know.


    • At this time we do not offer individual sides of the Pypes Muffler-Delete Axle-Back Exhaust. We would recommend contacting Pypes directly for this.

    what is the difference in sound between this and the slp loudmouths. Im looking for a deep muscle car sound, and these are more in my budget but I also don't want to cut corners on the sound and I get the feeling these are a little more raspy


    • The Pypes Muffler-Delete Axle-Back Exhaust will be raspier than the SLP loudmouths yes.

      Best bang for your buck axle-back

      We had a little struggle with the fit and finish while installing this axle-back. The exhaust hanger on the back of the right axle-back was welded way to high on the axle-back to allow the tip to line up with the other one. We just cut the exhaust hanger off and welded it back lower on the axle-back. Took a little extra time but no big deal. The exhaust sounds great now and has a good muscle car sound. It definitely turns heads when driving by.

      A lot louder than I expected, but I love it. The fit was a little uneven at first, the right sat lower than the left, but it wasn't difficult to even them out.

      Went on and sound great!

      Shipped to my door in 2 days, I alone took off my stock exhaust and installed the new pypes axle-backs. Everything fit good and and went smooth. They have that deep throaty growls idling; that just makes you want to mash the gas pedal.

      Terrible Fitment

      My 2007 mustang GT sounds amazing with these on! They did not fit at all though with the hangers on the pypes axle back. Had to get universal hangers to make them fit properly. American muscle had amazing customer service though with my problem though!

      Sounds amazing but fitment Requires work.

      These sound amazing paired with an offroad x pipe. Nice deep tone with a gargly idle. the fitment however, we had to cut part of the metal piece where the hanger goes becuz on was too long for the hanger and the other one was too short. But over all amazing.

      Sounds Good/Very Disappointed in the Fit

      I knew there were going to be issues with the hangers based off reviews, but the professional who I paid to install this had to consult another shop on how to install these things after two long hours of attempting to do so himself. I personally love American Muscle as a company. Good products and excellent customer service. I'm frustrated however on how they can carry a product where there are such issues with the fitment. Don't get me wrong. They sound incredible! I had the Flowmaster American Thunder Axel-back prior to installing these and they sounded good, but they weren't loud enough. Now, they are freakishly loud and throaty. She's breathing better and I have noticed a slight difference in power. I mean I cannot describe the looks I get! If you get these, they look and sound incredible, but consult the professional who you plan on installing these prior to ordering this system and give them a heads up on the burden of the installation. Aftermarket parts may have the reputation of being poor, but when I came across American Muscle five years ago, I was proven wrong. I have been amazed by this company's product for five years now. This product didn't make me completely disregard this notion, but it is a true disappointment about they haven't corrected this issue.

      Pypes axleback

      I purchased this kit with the pypes v6 dual exhaust conversion kit and these fit up perfect. The sound of the muffler delete is for sure what I was looking for. The install took about 2 hours but only because I had some issues tapping the bolt holes for the left side hanger, other that that it was a fairly simple install. The black tips really set it apart from other axle backs. 10/10

      Awesome Sound!!!

      These Muffler-deletes are the way to go! They put a big smile on my face when I started the engine for the first time, and really make you wanna hit the gas! These Muffler-deletes are not irritatingly loud, (for an 05 mustang GT) but they are for sure noticeable! I would totally recommend Pypes muffler-deletes to anyone who's looking for a loud and aggressive tone.

      Great buy/sound for the money

      I picked up these axel-backs to convert the stock exhaust for a little more aggression and can comfortably say you will not get a louder or more aggressive sound for under $300 with the cats still in place. PROS: Easy install (took dad and I about two hours because he broke one of the binding clamps with the breaker bar). Very aggressive when on the throttle though not much louder than stock when crusing around town. Affordable and good looking. CONS: No major cons really, parts are quality and a good value. NOTE: Keep your stock mufflers!!!!!! Depending on your location, these parts may not be street legal because of noise pollution. I haven't been ticketed yet but if you are disrespectful about the times you fire it up and floor it around people, you will probably hear from the police about it.

      These Axle-Backs Sound Great!

      The Pypes Muffler Delete Axle-Backs are a great addition to my Mustang. For the price of these mufflers, you cannot beat the sound! They are sure to wake up your neighbors in the morning and definitely will turn some heads. The only problem was one of the hangers on the right side had to be cut and re-welded by the person I had my mufflers installed by. I would recommend this product to anyone with a 3 valve Mustang looking for an aggressive exhaust tone, but with no tune required.
