Review & Installation Video

Review & Install Video

Hey, guys. Stephanie with here with my review of the Pypes Off-Road Shorty X-pipe available for Pypes long tube header equipped 2005 to 2010 GT Mustangs. Whenever you go from a shorty or a factory header setup to a long tube, you're going to need to change your midpipe to a shorty midpipe. There are a few options out there, but the general rule of thumb tends to be that you should not mix brands. If you want Pypes long tubes, you should stick with a Pypes midpipe. So as far as who this is going to be for, this shorty X-pipe is going to be for the GT Mustang owners that plan on upgrading to long tubes but want to do so in a cost effective way so they're looking at the Pypes long tube headers. Long tubes and a shorty midpipe go hand in hand since you need one to install the other. Usually, those installing long tubes are looking for power gains and an improvement in sound as well. Long tubes and a shorty midpipe have a different iconic type of sound that's hard to ignore. Along the lines of gains, long tubes and a shorty midpipe usually give midrange to top end gains, generally speaking. You may not necessarily be installing the long tubes and a shorty midpipe for sound, but you are going to get a huge change in sound. The long tubes alone are going to change the sound of your exhaust. When you combine that with changing the midpipe, you can expect a pretty big difference in sound, and you're looking at a brand new sounding Pony when you're done. Looking more at the midpipe itself, we're looking at a two and a half inch midpipe that's going to work with the Pypes headers. This is a stainless steel X-pipe, which is really nice to see from an inexpensive midpipe since the material of the midpipe drives the price point. You get the best of both worlds here with a corrosion resistant midpipe and a low price. This is an off road X-pipe, meaning that it has no cats. Normally, an X-pipe is going to have more of a louder, raspier sound as opposed to the deeper note of an H-pipe. Being catless means that this X will flow more than the factory midpipe would for sure, but you have to keep in mind things like emissions, and there's always that chance of the check engine light. But speaking of the check engine light, when you switch over to running long tubes you will need a tune. A tune here will not only help you get everything out of those expensive mods, but one of the main purposes of the tune with long tubes is to turn off the rear O2 sensor so you won't be getting a check engine light. Circling back around their price, you're looking at spending just over $200 for this X-pipe right here. Also, keep in mind that you won't be running this midpipe without a set of Pypes long tube headers, so you can factor those into the price of the shorty X-pipe. These items go hand in hand since you can't really install one without the other, which is another reason why long tube headers are an investment. So at the end of the day, you're looking at both power and sound gains here. Keep in mind that all of your gains will change depending on your setup and your tune, and in addition to that, you're also going to get an awesome change to your exhaust tone. The install of the X-pipe alone is not difficult at all. It's just a basic midpipe swap that doesn't involve removing any other items or any cutting. But, since you'll most likely be installing this along with those Pypes long tube headers, you can expect a project. Because of the combo install you can expect a full three out of three wrenches on this one, and a full day in the garage if you do decide to tackle this yourself. If you don't have a helping hand or you don't have much experience in this area, it might be better to just take the car to a shop for the install. If you do tackle this yourself, just know that you can do it on a jack and stands but a lift would make it easier for sure. Like I said before, the midpipe is easy enough to install. The difficult part will be installing the headers. You're going to need your toolbox for the install along with an assortment of different sockets, wrenches and extensions. A lot of this install obviously requires working in some pretty tight areas. While everything is straightforward, getting access in this area is usually tricky. Having a helping hand in this case is really going to benefit you. At the end of the day, it's all going to be worth it. So wrapping this up here, the Pypes shorty X-pipe is going to be a must have for anyone that's looking at running Pypes long tube headers. It's an off road stainless steel X-pipe. And as always, I suggest you check it out more online for yourself. I'm Stephanie, and for all things Mustang, keep it right here at

Increases Horsepower and Torque. The Pypes Beast Super System will greatly improve your S197 Mustangs exhaust flow over the restrictive stock manifolds and piping for a measurable increase in rear wheel horsepower and torque.

Complete Kit. The Pypes Beast Super System is a complete exhaust system that includes a pair of Polished Long Tube Headers, an Off-Road Shorty X-Pipe, and the "Pype-Bomb" Mid-muffler Super System Cat-Back system.

Aggressive Throaty Sound. This Pypes Beast Super System features two high flow straight-through M-80 Bullet Mufflers that are mounted directly after the off-road X-Pipe to produce an aggressive deep throaty muscle car tone with the help of the same stainless steel resonator tips that Pypes uses on their signature "Pype-Bomb" Axle-Back Exhaust kit.

Quality Materials. The Headers are constructed from free flowing mandrel-bent 1-5/8" polished 304 stainless steel, where the X-Pipe and Cat-Back are made from 2.5" 409 Stainless Steel tubing with a set of 4" polished 304 stainless steel resonator tips for great modern Muscle Car styling.

Application. The Pypes Beast Super System Exhaust kit is specifically designed to simply bolt-on in place of existing stock exhaust system on the 2005 to 2010 4.6L GT or Bullitt Mustang for more power and a louder more aggressive sound. Intended for off-road track use.

Is this going to be viable for a daily driver In the summer my car is my every day driver, im just not sure if this is going to be to loud, I don't want to have to take it off cause because of the cops ect.

  • Its gonna be fairly loud anytime you remove the cats on these cars so with the added mid mufflers it may calm the noise down more than if it were just the pype bomb tips. I had bassani offroad x pipe with the axleback pypes bomb and it was obnoxious my neighbors hated me so I put cats back on

Helpful (2)

Is there a "catted" version of this product? I like my Pypes axle-backs and their quality and price point is closer to my level of desirability, but I still have to pass emissions each year.

  • It does not appear that Pypes offers a set like this in a catted version. We do offer the Kooks Header and Catted X-pipe Combo - Manual which I have provided a link for below. Feel free to call or chat in we can always build you a combo that best fits your goals.

    Pure awesomeness

    First off the removal of the old was pretty easy. The install was a tad harder, but completely do able in the garage with basic tools. The longtubes were a pain to put in even though this was my second install on a mustang. Definitely worth the money. I do wish the exhaust pipes weren't in so many pieces, it would have been much easier to align everything with one fewer pieces. Sound is pure awesomeness.

    stang it!

    Not happy that you have to use the original band clamp from your stock exhaust, i would rather have paid a lil extra to have this new as well but overall this is a very good system for the money. the fit is spot on, was not that bad of a job to do would rather do it on a lift and not jack stands but i live in the REAL world off to enjoy!!!!!!!

    Super Beast

    Overall the full exhaust system is a great product. Kinda disappointed with the sound. But once I installed comp cam stage 2 it really brought the exhaust to life. Great fit and finish. Had the pype bombs powder coated black to match the style I was going for.

    Great but horrible

    Well, first off two major problems. One of the m80 cyclintrical mufflers had a one inch crack. I just welded it. Couldn't wait to ship things back and wait for new parts. Second, all joints with supplied clamps leaked. Had to take all joints apart to apply hi temp gasket. That and the extension supplied was not correct. Had to cut cut and file down the guides. For the money shouldn't have to deal with any of that. If I knew that's how it would have been I'd take my money else where. All in all end result came out good, great sound, good performance gain.

    The system looks good, sounds good, and is the perfect sound for what I was looking for. I coupled this with the Pypes cutouts and it will definitely turn heads.

    It's Good For The Money

    To start things off I AM biased in this argument. My first mustang (the same model) had Hooker Headers and XPipe and sounded like a stock car, I loved it. Sadly, that mustang and I ate a rock face head on and had to start from scratch and was lucky enough to find a 2007 GO Mustang GT with only 9k miles (wow). I bought this combo kit because for this price I got an entire system compared to Hooker which cost more for just headers and x. Problem 1: Installation. Jimminy Christmas. From the oddly shaped headers to the seemingly incorrectly manufactured cat-back, this was a nightmare. GET THE BRACKET RELOCATION KIT. Problem 2: Sound. Coming from stock car expectations, I wanted that absurd idle and the WOT sound to rival a top-fuel funny car. I was let down when I turned it on for the first time. THIS DOES NOT MEAN IT DIDNT SOUDN AMAZING. It was SO much better than stock. The rumble was reminiscent of a classic muscle car. I loved it, but wanted the sound of my other Mustang. So what do I do? I got to NAPA and get some 18in pipe and replaced the mufflers. Now I effectively wake the dead. Closing Statement: These have a good rumble at idle and sound great WOT. If you are expecting much more, don't gripe, straight pipe. You get what you pay for

    What a Beast! the exhaust note the GT deserves!

    I'm so glad I went with this set up! The install went great and without a hitch! The only thing that I could recommend is to have a muffler shop stagger the m80 mufflers, if not you get some slight drone from about 1700-2000 rpm but it doesn't bother me. The kit did only come with one 02 extension so I had no order another, but no big deal.

    The whole package

    First it was skeptical about buying this but I just went for it, I'm happy I did. I couldn't ask for a better fit, everything fell right in place. The sound is amazing! A little raspy, not too loud at idle, but when you floor it you know why they call it the beast. I'm not sure how much power/torque I gained, but you can defiantly feel the power added.
