    Hey everyone, Justin with AmericanMuscle.com, and this is our PowerPack Bolt-on build up for all 05-09 Mustang GTs. The goal of this Power Pack is to take our stock 07 GT, and combine it with some of our most popular performance bolt ons. The result will be twofold, we’re going to add more horsepower and torque at the rear wheels, while really cranking up the volume on our 4.6L to make our GT sound as tough as it looks. Currently, our 2007 GT is bone-stock performance wise, so let’s get it outside and hear how that stock exhaust sounds, and then get it back on the dyno to get some baseline numbers down. So our stock dyno run gave us 259 horsepower, and 289 ft/lbs of torque. Alright, now that we’ve got some baseline numbers from our 07 GT, we’re going to talk to Mike Wilson, our lead calibrator from Bama performance, to walk us through some of the mods we’re going to do today. Mike, what have you got up first for us? Mike: Well, first we’re going to install this Airaid race cold air intake which is a great first mod, it’s going to increase air flow, give us a big gain in horsepower and torque, and has a really easy install. Justin: Alright Mike, I know with some cold air intake systems you need a tune, sometimes you don’t, what’s up with this Airaid? Mike: The Airaid Race cold air intake does require a tune, because of that, we’re going to install a Bama performance 93 octane race tune, which is going to increase our horsepower and torque by adjusting the spark curves, fuel map, the drive by wire calibration, really improves the horsepower and torque. Justin: That’s awesome man, I know in addition to that we’re also going to throw in a Pypes off road X-pipe, and also a Pypes axleback system as well, what can we expect from that? Mike: That’s also going to free up the exhaust flow which is going to give us more horsepower and torque, and it’s going to sound incredible compared to your stock exhaust. Justin: Our second dyno run with all the performance parts installed on our 2007 GT gave us 293 horsepower, and 309 ft/lbs of torque, making for a peak gain of 35 horsepower, and gains of 36 horsepower and 29 ft/lbs of torque throughout the curve. Alright Mike, that’s awesome, what do you think of the results? Mike: exactly what I expected. We’re putting the cold air kit on, the exhaust, and wrapping it all up with a custom tune, we’re definitely going to feel a big difference in the street. Justin: Awesome. Well, with that said, we’re going to get our 07 GT back on the streets, because I’m dying to hear how this Pypes combination is going to sound versus our stock exhaust so thanks again, Mike. Mike: Any time. Justin: Now that we have our 07 GT out on the road we finally get to see these mods in action and I’ve got to tell you they’re really doing their job. Our GT just pulls so much harder on the upper RPM range, which means our car is breathing a whole heck of a lot easier. The best part is, they installed easily in about 2 hours, with simple hand tools and a few floor jacks. Be sure to check out our other 05-09 Mustang GT bolt on build ups, where we work on our appearance, help get our GT off the line, and make it handle a little better.

    Balances Exhaust Gases. The Pypes Off Road X-Pipe is excellent when it comes to balancing out the gas pressures in your exhaust system. This Pypes off road x-pipe creates more power and torque than a traditional H-pipe. Why? Because the exiting exhaust pulses are merged at the "X", resulting in less exhaust back pressure for more power.

    Race Car Growl. This free flowing Pypes x-pipe for the 2005 to 2010 GT's not only increases power, but it also adds a raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design.

    Modular Construction. Pypes unique three piece modular construction makes it quick and easy to add or remove catalytic converters to your exhaust system in just minutes, depending on your driving needs.

    Durable Stainless Steel Construction. Pypes uses sturdy 16 gauge 409 stainless steel mandrel bent 2.5" tubing for improved exhaust flow and features welded reinforcement plates for additional strength.

    Application. This Pypes Off-Road X-pipe is designed to be a direct bolt-on for the 2005 to 2010 4.6L GT Mustangs with either aftermarket short tube headers or the factory manifolds and a dual catback exhaust installed. Intended for off-road, track use only, does not include catalytic converters.

    My catalytic converters are going bad i just want to delet them. Does this kit cover that? All stock btw

    JesseN

    • The Pypes Off-Road X-Pipe would eliminate the OEM catalytic converters, as well as change your OEM H pipe to an X Pipe. You will get p0420 and p0430 codes for catalyst efficiency, which can be corrected with a tune.

    When I get that check engine light, I know I can use a obd2 scanner to remove it but will the car still run rich?

    JustinD

    • To correct the check engine light with this Pypes Off-Road X-Pipe or any off-road mid-pipe you will need a custom tune. Using an OBD2 scanner will only clear the code, but it will still illuminate after a drive cycle or perhaps even sooner because it does not actually correct the issue.

    Just bought an off road xpipe and It's already installed. i don't have the money to buy a tuner. how bad is it really to not have a tune on it.

    JacobM

    • The Pypes Off-Road X-Pipe does not require the use of the tuner, however, for optimum performance a tuner would be needed to get the most out of the xpipe.

    • Hello! The Pypes Off-Road X-pipe is designed to be a direct bolt-on for the 2005 to 2010 4.6L GT Mustangs. It will not require any additional parts.

    after install is it mandatory to have a tune? If the tune isn't done what are consequences ?

    JacobM

    • Hey Jacob, For an off-road pipe it is mandatory to get your car tuned. Not getting it tuned will cause the car to throw engine codes. the consequences of the codes is that the computer will think the car is running lean so itll add more fuel making it run rich in actuality which can be harmful.

      Loud, Raspy, Easy Install BUT!

      Everything went on fine, sounds great. Only thing is that AM wont tune to get rid of engine codes for CATs. Would of been nice to know ahead of time or even for warning before buying any exhaust.

      Hands down great product, buy it!

      This product really livens up the car i had the catless H b4 and the car felt sort of sluggish and sounded a little off paired with the Borla atak but once i put this x pipe on it sounded so much more free flowing ( if that makes sense) so far love it. Not so raspy as everyone thinks. Cost 90 bucks to install. Only giving 4 stars because UPS cant seem to get things right. My packages delayed.

      2010 gt pypes off road x pipe

      When I received the pypes in the mail it had 2 drivers side legs instead of 1 drivers side and 1 passenger side. American muscle wanted me to wait for them to send me a return label, package it back up, send it back, and then wait for a replacement. Ridiculous to have to go through all that for a mistake that wasn’t my fault. But thankfully I called pypes and they sent me just the passenger side free of charge and it got to my house in 2 days. That being said the fit was really good. I cut the hangars off because I don’t have hangars at the trans brace. Sound is decent and I think getting better as it gets driven. Have not had a check engine yet and all o2 sensors plugged back up without any extenders or mil elimination.

      LOUD

      Had the Pypes muffler delete with the stock manifolds and stock h pipe w/the cats on my automatic, and was that loud. Pairing the pypes off-road x pipe with the pypes muffler delete MORE than DOUBLED the loudness of the car and makes me feel sorry for my neighbors. This does give a raspy sound around 2000-3000 rpm when it shifts through the gears and flooring it on the highway. Simple installation with two floor jacks and jack stands, took me a little over 2 hours from start to finish. Pro tip, the top bolt on the passenger manifold is a little tricky to get to when lying on your back, I was able to get to it using several socket extensions to remove it. I was able to avoid getting the check engine light by unplugging the battery before removing anything else, but I do plan on getting a tune along with a CAI soon.

      There's a Richard petty in all of us

      I paired this with the pypes mid muffler catback. Let me say I am more then happy. If you drive miss daisy pass this up, if you want everyone in a 9 mile radius to hear you get this exhaust combo and thank me later. If you want to be scared driving thru the city because it sounds like you're driving a stock car, get this :-) it took me and a friend 4 hours start to finish to take old exhaust off and install this x pipe, catback, cai, and tune the car on jack stands. Car had 48000 miles on her and install went as smooth as cream cheese.

      Super easy, goes great with an axle back exhaust like flowmasters or something else that's not too extreme. This will make your mustang LOUD! Haha If you don't want it to be too loud keep the stock mufflers and it'll go together perfectly. 5 stars The stock cats are a PAIN to remove fyi! Lol The bolts don't want to budge either so you'll have some fun with that.

      Let’s just say if you want to wake the dead get a set of the Flowmaster outlaws to go along with the x pype. Cold starts awake the neighborhood . . . Probably going to get a different cat back setup because it is a little to loud.
