Hey I’m Justin with AmericanMuscle.com, and this is my quick look into the Pypes muffler deleting axle back exhaust system, fitting all 2005-2010 Mustang GTs, and GT500s. This axle back is for the Mustang owner who is looking for quite possibly one of the loudest setups with the cats in place, all for a price that’s going to be very hard to beat. Besides really cranking up the volume on your 3 valve, the muffler deleting axle back will increase the flow of exhaust, by eliminating the restrictive factory mufflers, which should equate to some more power at the rear wheels. Construction wise the Pypes system utilizes full 304 grade stainless steel throughout, including the mandrel bent 2.5” tubing and hangers all exiting out the removable 4” slash cut tips. Even though this is an axle back and the install should be relatively straightforward, you may run into an issue with modifying or relocating some of the hangers, as some of our customers have pointed out under the review section. Either way just be sure to leave yourself about an hour to get everything bolted up. Now let’s hear how the Pypes muffler deleting axle back sounds compared to our factory exhaust.

Good sound not bad
Overall the product was nice, and sound amazing it’s a lot louder than i expected. Only complaint is the passenger side hanger being too long like many other people have commented on. It’s about 2-3 inches too long and really stands outHelpful (0)

Not worth it
Fitment was horrible, passenger side pipe hung low by about 4 inches. Can be fixed buy cutting and tacking the hanger to the correct length. If you are going to buy these you might as well just do a straight muffler delete. This exhaust doesn't make much of any changes to sound (sounds worse than stock in my opinion) and is not worth the time, effort and money.Helpful (0)

Pypes Muffler Deletes are LOUD
Be WARNED, these pair of muffler deletes are VERY LOUD. If volume is what you want for under $300 then these are your best bet. The fit was great and these are very simple to install. This exhaust screams at WOT but if needed you can be fairly quiet if you shift at 2500 rpm. Would recommend to anyone thats looking to turn up the volumeHelpful (1)

Sounds good but fitment is not the best
I will say the packaging is very nice and the sound once installed is amazing but the fitment on the passenger side tailpipe is terrible. The hanger is too long so the pipe sits lower than the drivers side.Helpful (1)

Sounds great but..
Exhaust sounds great, but the fitment is off by a lot on the right exhaust. For $260 I’d expect both sides to fit, I have to take my car to an exhaust shop so they can make it rightHelpful (1)

Nice muscle sound
The pypes really change the sound of my mustang. It has that nice muscle sound. I love it when I get down on the gas. My neighbor probably hate me now, when I crank up the mustang in the morning. The one problem I had was that I really had to adjust the passenger side.Helpful (0)

Would suggest using a full lift for this, I used two jacks and some wood. With help from my family, we finished it in about 2 and a half hours. It was totally worth every penny because it sounds amazing.Helpful (1)
Is there a difference between these and just a straight pipe for a muffler delete? Other than these are just made by Pypes...?
The Pypes Muffler-Delete Axle-Back Exhaust (05-10 GT, GT500) are a Muffler-Delete Exhaust. There will be no muffler included in this kit. These Pypes are designed to increase air flow and produce the loudest sound possible while running stock catalytic converters. Pypes Muffler Delete will be fairly similar to running an actual straight pipe.
I have an 05 V6 with a dual exhaust system. Will these fit?
Yes, this is compatible with the dual exhaust conversion kits for the V6 Mustang.
I have an 05 Roush Mustang, will the Roush left and right side square exhaust tips fit on this muffler delete?
We cannot confirm fitment of Roush tips with this exhaust.
Is this compatible with BBK True Dual Exhaust Conversion Kit (05-09 V6)?
The Pypes Muffler-Delete Axle-Back Exhaust will not work with the BBK True Dual Exhaust Conversion Kit without the use of GT over axle pipes. We typically recommend purchasing a complete cat-back exhaust to go with the True Dual kit.
installed on my 08 GT, and the passenger side hangs a good bit lower than the driver side , , everything is in place as it should be I don't understand ..
We would advise to check that everything is lined up properly, the bolts are tightened and secure, and that the clamp is on there as tight as possible. If you were still having further issues with the install of this item please feel free to reach out to our customer service department by giving us a call at 1-877-887-1105 or by chatting in with us we would be glad to help!
We have not attempted to use the Pypes Muffler-Delete Axle-Back Exhaust with Roush Tips on a Roush rear bumper, but we believe the tip alignment may be off with this setup.
The Pypes Muffler-Delete Axle-Back Exhaust will not have a specified or guaranteed decibel level, however it is safe to say that as a muffler delete, this will be very loud.
The Pypes Muffler-Delete Axle-Back Exhaust will not fit a 4.0 V6 with Pypes dual exhaust. If you have any other questions or concerns feel free to call or chat in.
The Pypes Muffler-Delete Axle-Back Exhaust will install after all emissions control devices so these will have no effect on emissions testing. Unfortunately we do not have access to state inspection laws for every state, however in our home state of PA, a muffler is required for inspection if one was originally equipped. We recommend checking with a local inspection station to verify legality in your area.
The Pypes Muffler-Delete Axle-Back Exhaust will fit the Shelby GT models.
There should be no issues with the hangers for the Pypes Muffler-Delete Axle-Back Exhaust (05-10 GT, GT500)!
The Pypes Muffler-Delete Axle-Back Exhaust will have a rounded tip design which the Roush rear Valance, item 69103 will have a square tip design which will not properly fit in alliance with the Roush design. https://www.americanmuscle.com/roush-rear-valance-0509.html
The Pypes Muffler-Delete Axle-Back Exhaust will give a raspier/racier sound and less deep/rumbly sound due to their nature as a muffler delete.
As long as the piping is 2.5" on your exhaust now then these would fit. However, these would give more of a higher pitch raspy sound than the violators. You should also not have an issue with the hangers.
A raspy sound is so based on preference, if you are interested in the Pypes Muffler-Delete Axle-Back Exhaust we ask that you listen some videos of the exhaust and see if it fits your needs and goals for sound quality. Feel free to call or chat in to go over the sound and goals for your build with one of our Mustang experts.
