      Review & Installation Video

      Dave with AmericanMuscle.com, 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.

        Way Better than Stock

        I bought these to replace some ebay shorties that didn't fit. I will say that the Ebay shorties were MUCH MUCH bigger where the collector bolts up. These are not much bigger than the stock exhaust manifold. However they weight 9lbs less and main performance gains are HUGE between 2.5k-4.5k rpms. Sounds much better. Overall I would highly recommend these for anyone looking for cheap weight loss and 10lb torque. Look way better that stock as well.

        Have not installed yet. Only issue is, they are not polished like the pic shows. But, I’m not building my car show. I’ll add a pic when installed.

        Horrible fitment - poor build quality

        Plan on 12-14 hours to install these - with a lift. If you're installing these on jack stands, I feel bad for you son. I got 99 problems and these headers are every one.

        Good headers

        Not bad for the price. But you get what you pay for. You will have to do some adjustments to the bolts you use due to how the headers are. I used a mix of old studs and new bolts and worked just fine.

        Fitment

        Very disappointed that I spent the money on this product only to get it and then have to modify it for it to fit, had to drill out the holes so they would line up with the holes on the block.and to be clear this is a issue with Pypes not American muscle. Although I did eventually get them on the car and they do sound great I will not purchase Pypes products again

      Are these shory headers compatible with other exhaust manufacturers? Hello, I have a V8 2010 GT Premium. I recently just purchased a flowmaster axle back exhaust. I now would like to buy a set of chrome shorty headers and shortly there after a mid-pipe, but i am not sure if these (pypes) will work with other manufacturers? Should I stay consistent with Flowmaster for a complete exhaust? Any suggestions or recomendations you can offer would be greatly appreciated! Thanks, Rob

      • yes, you can mix and match....on my '05 gt i have bbk shorties, after market h-pipe, after marker over the axle mid pipe and slp axle back and it sounds muscular (not crackly like an x-pipe)...chrome headers will "blue" on you quickly...i use 304 stainless on my headers (409 stainless will blue, too) and most of my exhaust so it'll last forever (they'll never "blue" on you)....ceramic wil keep their color, too...whatever your budget and desires can handle....flowmasters make a good complete system for your car too

      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.

      Will these shorty headers and cut and clamp X-Pipe fit together?

      • These headers are designed to fit otherwise stock applications, so as long as the mid pipe in question is also designed to fit an otherwise stock application, it will be safe to say they will work together.

      Do I have to use the new header gaskets that come with this, or can I use the ford performance header gaskets?

      • We recommend using the gaskets that are included with the headers.
