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.

are there any other parts that I need to have or are the x pypes able to go in without any other parts being purchased

  • 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.

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.

  • 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.

Helpful (3)

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

  • 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?

  • 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.

Will this delete my cats?

  • The Pypes Off-Road X-Pipe, and any other off road x pipes will eliminate your catalytic converters.

    Insanely loud

    Paired this x pipe with a pypes muffler delete and people aren't kidding when they say it sounds like a stock car. It is so loud it can be heard blocks away. I've never heard anything like it. I am not a fan of the sound of males between 2000 and about 2800 rpms,its a really raspy screaming,almost metallic type sound and I'm more into the deeper muscle car sound which I probably would have gotten from an h pipe. Overall its exactly what it claims to be though,loud and great air flow. I got no check engine light as some did,but o did lose quite a bit of power in the lower rpms as I haven't tuned it yet. When I took the muffler delete back off to try it with the stock mufflers ot quieted down a lot AMD to me sounded better,AMD I gained a lot of power back. I think I will sell the deletes and put a decent set of race mufflers on it and I should have exactly the sound I'm looking for, or close. If you want everyone in a half mile to hear you, this is the exhaust for you. Install was done in a few hours. Would have been faster but my buddy snapped one off.

    Pretty Cool

    Overall it's a great product for what it's intended to do which is to make your Mustang loud. A tune will be required in order to fix the Air to Fuel ratio. The PROS of this modification is your Mustang is loud as heck and you have a little bit better air flow. The CONS, however, is it's illegal in California, the smell that comes from the pipes is repulsive and if you stand close enough to it, it will soak into your clothes and you will smell like gasoline. The header bolts are a hassle to access and reapply.

    Pypes Catless X pipe

    I bought this because I wanted my car to be louder and I was blown away it is insanely loud the cold starts are brutal, and the burbles when you downshift are amazing. I have stock headers the Catless x pipe and no mufflers and it’s one of the loudest cars I’ve ever heard. I switched from an H pipe and the tone is sooo much better. Pretty easy install, the hardest part for me was getting the old 02 sensors out, once I finished I took it to a local shop to get welded.

    Pypes Off-Road x pipe

    Recently pull the trigger on the pypes off road x pipe and honestly could not be any happier with it! Great quality material and an even better price point. I am by no means rich so being able to get a great quality product you can count on and trust goes a long way with me. Great install, everything fit as promised and had no problems related to the pipes. Will keep pypes and American muscle on the top of my go to list!
