Free Up Horsepower and Torque. Replace those heavy and restrictive cast iron factory exhaust manifolds with a set of Pypes free flowing, lightweight, stainless steel shorty headers that will allow your GT to breath better than stock for more power.

Dave with, and I have with me an item that’s highly reviewed and highly rated by our customers. It’s the Pypes polished shorty headers for the 2005 – 2010 Mustang GT. A shorty header is a great entry level header, especially when compared to your factory manifold. The factory manifolds are cheap, one piece cast iron designs, and they are easy to manufacture and extremely restrictive. In fact, they retain heat, they restrict exhaust flow, and look rusted and ugly before you even know it. A shorty header is going to go directly in place of your factory exhaust manifold, meaning it is going to go into your same exact location, it’s going to have the same length as your factory manifold, and bolt up to the head on one side and your factory midpipe on the other, meaning there are no other items to purchase and no other modifications required unlike when you run the long tube headers. Unlike your bulky and restrictive factory exhaust manifold, these Pypes polished shorty headers, they’re made from stainless steel, they’re 1 5/8” diameter and they’re guaranteed horsepower and sound the moment you bolt them onto your Mustang. Since these are going to allow the motor to expel the exhaust gases faster from the car, you can count on these delivering not only more sound, but about 8-10 more horsepower, with no tuning required. A common question our customer services reps get all the time is “Hey, if I pick up a shorty style header, do I need a shorty mid pipe?” The answer is no, a shorty style mid pipe is only utilized when you pick up a long tube header. A shorty style header is going to go ahead and use your factory length mid pipe to ease installation. Just by looking at these headers, you can tell they’re a high quality product. They’re polished to a shine, and they’re mandrel bent, to guarantee you’re going ot get top notch looks, and performance out of these headers. Pypes has taken a lot of time to do in house testing on these headers, which are made from 304 stainless steel, they’re making sure they’re going to outshine, outflow, and outlast your factory exhaust manifolds, and like all other manifolds from Pypes, they’re backed by a limited lifetime warranty. The high polished shine is going to come in handy when trying to view the header, it’s located way down in the engine bay and can be a bit of a bear to view, as well as to work on, so if you do leave the install to the professionals there’s no shame in that. If you think you’re up to the challenge, I’d recommend you leave yourself a full afternoon if not a full day, and I would certainly lay out the tools beforehand to make it that much easier. You’ll want to have a full socket set with extensions, you’ll want to get some penetrating oil to get the factory manifold bolts off, you’re also going to want to have some gasoline remover to make sure everything is cleaned off before you install your new headers. Even though these headers are designed to bolt up to your factory mid pipe, we recommend you have the entire exhaust system upgraded at the same time to get yourself the maximum gains in flow, and the maximum gains in performance. I’ll tell you, by getting rid of the factory mid pipe and upgrading everything at once, you’ll absolutely notice a tone change by the added airflow. The Pypes polished shorty header comes with all the hardware and gaskets needed for installation, and it works well with your factory length mid pipe or aftermarket full length mid pipe, to add performance and sound to 2005-2010 3 valve Mustangs.

Will this work with pypes off road H-Pipe? I was considering buying new headers and a mid-pipe for my 2007 GT/CS. The car already had Bassani mufflers already on the car when I got it. I like the sound of the exhaust that results from the combination of the Pypes off road H-Pipe and the Bassani mufflers. I was wondering if the Pypes shorty headers would work with the off road H-pipe and if it would keep the old school rumble that results from the H-pipe.


  • As long as you keep an H-pipe, you will get the old school rumble. Your exhaust will get slightly louder though.

2008 Bullitt fit? I have a 2008 Bullitt with Pype bombs and pypes high flow cats but the stock H pipe. Will these headers still fit my setup? or will i need a new midpipe?


  • Sure! These shorty headers bolt into the factory location and you can use your stock mid-pipe or an aftermarket. Your current setup would be perfectly compatible!

    I already had the Pypes Violator axle back kit installed. I finally ordered the Pypes off road mid pipes with "X" pipe ,and these headers. After paying to have these installed the exhaust note became extremley aggressive and very loud. Also I gained the ability to easily spin 3rd. Great product! Thanks AM.

    Only one problem

    Got these on my 05' gt and arent a bad product, but I don have problems with the nuts coming loose on these repeatedly and disappearing. Tried double bolting since it gets to hot for lock tight. Thats the only other concern, these heat up and heat up fast.

    sound great hard install

    so after 12 hours of trying to install these with my buddy i finally gave up with them complete minus a stud.....way too many leaks to name but after a trip to the shop and 150 bucks they sound awesome and i can feel the improvement on pick up. bottom line if you are a hobby mechanic like me just pay to have them put in.

    First off I love the sound of these headers along with Pypes o/r X-pipe and Flowmaster axelbacks! Sounds like an animal! I do have a problem with my steering column rubbing and making it hard to turn so im gonna have to go back and lift the motor a tad bit but thats a quick fix! Cant wait for my next purchase from American Muscle!

    Pypes shorty headers

    I ordered these to go along with my pipes o/r x-pipe and catback, "the beast" package-Before my car was obnoxiously loud and had a raspy sparatic sound. I WAS going to try to install it myself at a local shop on miramar mcas, funny thing is when I went there was another guy there trying to install shorty headers on his mustang. He was there for 2 full days and was in the process of removing his front axel. I asked him, "would you rather have just paid $300 for a professional install?" he said, "dude I'm thinking about towing it right now." soo I took that advice and went to another local shop and paid $300 for the professional install. It took them 6 hours and the said they had to lift the motor and remove the engine mounts. When I went to pick it up, and they started my car, a tear ran down my face cuz it sounded so good! It was deffiently quieter BUT it sounded so smooth and it just absolutly roared. When I drove it, I immediately noticed my first and second gears were shorter(cuz I was going faster). I don't care what anyone says about shorty headers not giving you power. It's complete BS, cuz I deffiently noticed a difference. All in all though, I'm very happy with the selection I made by going with pypes shorty headers. I'd recommend them for anyone, especially at the price they're at.... A really nice upgrade over stock.

    Love These Headers

    I installed these headers at home in about 4 hours. What an improvement in exhaust flow and sound! I also installed a complete pypes M-80 mid muffler system with pype bomb resonators and off road x pipe. Installation was fairly easy due to the excellent fit of the pypes system. I recomend removing the motor mounts completely to allow for an unobstructed view of all of the mounting studs/nuts. I also recomend driving the car for a few days and checking for tightness. After I went over the nuts/studs the second time they were perfect. Simply put, these headers are outstanding for the price and increase in power!

    Sound sick and look great

    These took me a while to get on but were well worth it. They look great, sound sick, and now my enginee revs much quicker. I can't wait to get my new race tune for them.
