Review & Install Video
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.

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.
