Review & Installation Video

Review & Install Video

Hey I’m Justin with, 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.

Increase Performance. Bolting on a Pypes Muffler Delete Axle-Back to a stock 2005-2010 GT or 2007-2010 GT500 will yield an instant 5 to 10 horsepower gain. It features a unique "muffler delete" design for the ultimate in flow and power gains with an ultra aggressive sound!

Aggressive Sound. This Pypes straight through "muffler delete" axle back system is designed to increase air flow and to produce one of the loudest exhaust sounds possible with the stock catalytic converters still in place. This is the closest thing to running straight pipes on your Mustang.

Polished 409 Stainless Steel. This Axle-Back system from Pypes is constructed from high quality 409 Polished 2.5" Stainless Steel tubing and features a 4" rolled edge slash cut polished tip, that exits in the stock location for aggressive Muscle Car looks.

Application. Made to be a direct bolt on, this Pypes Muffler Delete Axle-Back bolts right up in the stock location without any modifications required on the 2005-2010 GT or 2007-2010 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.

I already have pypes off road catless x-pipe installed on my car and I want to get these axle backs to improve the sound but I'm a worried about losing power due to no back pressure. I've never run a straight pipe setup before.. Would I lose power with these?


  • You should not loose any power after installing the Pypes Muffler-Delete Axle-Back Exhaust.

I have bbk headers on my 2006 mustang GT and stock x pipe with catalytic converters with mac mufflers already on it. Will i see a big difference with this setup with headers on my car or will it sound the same?


  • The sound will slightly change when you add the Pypes Muffler-Delete Axle-Back Exhaust to your car. It will be more aggressive than what you have now.

I am planning on ordering this exhaust sometime next week, I am a little scared due to the fact that I've never installed an exhaust myself and I do not want anyone else install it for me, does the product come with step by step instructions?

Will this fit a 2010 mustang v6? If so, what modiffications?


  • Unfortunately, the Pypes Muffler-Delete Axle-Back Exhaust is only designed for the 05-10 GT, and the 07-10 GT500. You would need to have multiple modifications done in order for this to fit your 2010 V6. This Axle-Back will not be a direct bolt on.

    Perfect Sound

    I spent a while trying to decide on an axleback that I thought I would like. I knew I wanted a loud, raspy, and crackly exhaust so I eventually settled on the Pypes Muffler Delete. The Pypes delivered within 2-3 days. I was initially worried that I would have issues with the fitment. However, the Pypes are designed to fit perfectly. The issue arises because there is no clearance when sliding the Pypes into the hangers and trying to connect it to the mid-pipe. But if you take the hangers off of the frame of the car, it makes the install pretty easy. Unbolt the hangers from the frame, slide them onto the Pypes, connect the Pypes to the mid-pipe, bolt the hangers back on to the frame of the car, then clamp everything down. Immediately after the install, I went for a drive and it was like driving a new car. I was very impressed with how amazing it sounded. Very loud, raspy, and crackles and pops a lot. Obviously, it's a little louder within the car but no annoying drone. I've already set a car alarm off in a parking garage. I couldn't be happier with the Pypes Muffler Delete.

    I have always like to announce my presence with authority and these definitely fit the bill on my '07 GT500. Some say they are too loud but I'm an old school guy and don't understand why you buy a high performance car, modify it, and they say it's too loud. I bought mine a while back and don't really understand why the hanger issues haven't been corrected. Took a little extra time for the correct fitment but once you start modifying a car, you can't expect everything to just perfectly fall into place, so no big deal.

    Its the sickest sound ever. I been to a lot of car shows but I never heard any like this. I use to have megnaflow it wasnt even close to this. People get scared of it. The only bad thing was the hangers.

    Awesome sound

    shipping as super quick (as per the AM standards). Took these to a muffler shop to get installed. Took about 45 mins for the install. The Good: Tips look uber cool. The exhaust note is oh-so-awesome. The bad: the passenger side tip does hang a little lower that the driver side. Can be fixed by bending the hangers a bit. Overall, this product is awesome. The sound can wake the dead...!!!

    This is simply the best sounding exhaust system for the 05+ GT\'s. I have received nothing but complements since installing this system on my 07 GT. Not only is it the best sounding exhaust, but the price is great too.

    No doubt this exhaust sounds great but it kind of took a good amount of time because one of the hangers had to be cut and rewelded so that took some time

    Mean Exhaust from a V6 Owner

    I think I may be the first V6 owner to review this exhaust because I couldn't find any which had me worried of what to expect. No, the hangers don't line up even for the V6. Shop took care of that no problem. Worked great with the new Pypes x-pipe kit. As far as the bumper I bought a GT500/CS OEM re-manufactured bumper to replace the original (~$700 painted). However I had the original on for a while before I got the new one and cut some holes in it with a dremel. Honestly I thought would look terrible but for a really quick cut it looked great. Note that not only did I have to cut the driver's side hole, the factory hold had to be made bigger otherwise the bumper would touch the tip. You'll want at least a half inch of clearance. As far as the sound it's awesome! It won't sound like a V8 but it has a really nice raspy race car growl; not ricey at all. A couple little backfires here and there when rev'ing in neutral from a cold start but it stops when I start driving. It'll probably go away when I get my intake/tune or the computer adjusts for the new airflow (installed earlier today). I haven't tried resetting it yet as it's hardly noticeable. Tuner/CAI is the next upgrade!

    Hanger adjustments needed

    Like all of the other reviews, you do need to adjust your hangers, this was quite a pain to install the passenger side, but when it was in, it was very loud. I have the pypes off-road x-pip and now the muffler delete system...way to loud and raspy, putting pypes hi-flow cats on soon...will review after.

    This exhaust makes your car the best sounding thing on the road.There is A seat of the pants increase of power. Another thing the other reviews don't mention is that even if less than 10hp is added this exhaust also removes around 50 lbs of weight from the car along with a few other tricks it adds up. Only down side is the fit of the hangers.

    Pypes sound great, install was pretty easy too, Only issue I have isd the same as most of the others, the Right side will not line up and I don't have time to mess with it right now. I just find it hard to believe that after 3 + years of product reviews the company hasn't made an effort to correct this issue. Only other issue, I was told I would need the hanger kit, they are the same as the factory hangers, don't spoend the extra cash if you don't need to.

    Sounds great, but.....

    The exhaust sounds great! Has a nice rumble to it while the car is idling, and has a nice roar when you are accelerating past the 2500 RPM range up to about 4000 RPM. Only problem is that the hangers are not cut to the right length and shape to fit properly. I installed myself in just over an hour, and the right side ended up about an inch lower than the left. Took it to a performance exhaust shop and got the hangers fixed to fit properly for only about $10. Shop owner said it is an ongoing problem with these Pypes exhausts. Still happy with the purchase though.

    Great Sound

    Amazing from the get go. Deep, throaty sound, but still comfortable at idle speeds. The sound is perfect between 2000-3500 rpms, after that it is still loud, but smoother and more similar to the stock exhaust. However, quick accelerations are sue to turn heads. Another thing I like is the Pypes logo engraved atop the muffler tip. It adds a nice extra flair. Definitely worth every penny, the Pypes muffler delete is the best muscle car sound i have heard yet.
