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.

Is this product all i will need to delete my cats and stock H pipe and install? Also will i need any welding done?

Nick

  • The Pypes Off-Road X-Pipe will be a direct bolt in with no welding required. This includes everything required to physically install the pipe, however a tune would be required to keep the check engine light from coming on and setting p0430 and p0420 catalyst efficiency codes.

Will this work with Pypes Muffler-Delete Axle-Back Exhaust? I've heard that pairing the wrong X or H pipe to an axle back can cause a ton of drone, which type of mid pipe (X/H) would be best for sound and also less drone?

I have an 07gt with bbk shorties (on car when I bought it) and slp loudmouth axle back. Would these fit the shorties and would they go all the way back to the axle? If not, do they make an of road xpipe that would hook up to the shorties? Thanks, Tim

    Exotic v8 sound!

    By far the best money I spent on my 09 gt! Compared with my Borla stingers, the sound is bar none the best! You can make the car loud with with your own throttle response or keep it quiet with no drown just cruising! Very E92 M3 with aftermarket exhaust sounding with the perfect touch of the iconic mustang sound! Install wasn't bad, just requires some clearance to remove and some patients with stock header bolts above the big cats, other than that big weight difference between stock H pipe and o/r x pipe. I live in a neighborhood and I can control sound leaving without being loud. Again perfect sound with Borla stingers!!!!

    INSANITY!!

    I installed the pypes O/R x pipe on my whipple charged 4.6L 2006 GT using a buddy's car lift. Took the 2 of us around 45 mins to swap it out. 15 mins of which went in figuring out how to get the car on the lift because it is lowered 2 inches. 2x4's came to the rescue. Anyway, getting back to the point, we used air tools to get all the nuts/bolts off and even the removal of the stock H pipe went smoothly (which I hadn't expected). Make sure you have a long pipe that is wide enough to fit the back of a wider sized wrench that you will need to remove the O2 sensors. Also a swivel joint and an extension WILL be required to reach the flange bolt from around the cats. The new exhaust set-up: Stock exhaust manifold, Pypes O/R x-pipe, magnaflow over-axle pipes, flowmaster outlaw axle backs.= Absolute Insanity. Warning = This set up is extremely loud and think twice before purchasing this mod if your stang is a daily driver. You might get some hearing loss otherwise lol. I am running this set up without a tune for now. I have the whipple tune installed. I will eventually get it dyno tuned.

    Super loud

    Impressed with the quality of the Pypes O/R X pipe. But, paired with Ford Racing headers and SLP loudmouths it was not only LOUD but sounded too raspy. When accellerating it sounded like a truck engine breaking. Put my JBA axle back mufflers back on and the sound quality improved greatly. The X pipe fit perfectly. Just watch what you pair it with!

    Satisfied.

    Let's be honest upfront: LOUD. It's loud and from about 2500-3500rpms it has an incredible raspy growl. There's some vibration under the passenger side but I may just need to tighten some things back up. I would highly recommend a tune otherwise you'll be burning rich and you can smell it even In the cab sometimes.

    Due to the rusted bolts i had on my cats, I had an exhaust shop put these on for $90. Right as I left the lot, I couldn't quit smiling. These paired up with flowmaster outlaws makes a perfect combo! Kinda raspy but I love it. ITS INSANELY LOUD.

    Absolutely insane..

    I installed this along with the Pypes Pipe Bomb Axel-back exhaust on my 2006 GT and its a mean combination. I get nothing but compliments, neighbors, coworkers, random pedestrians, etc. It's very loud. Sounds like a suped up muscle car. I smIle just starting it up. Cold idle is extremely loud, once it warms up it calms down but not too much. I like it loud and it delivers. I've scared a couple of girls while pulling out of a parking lot and get thumbs up in traffic. If you're looking for a very aggressive sounding exhaust then this Off Road X-pipe is for you. It's literally a bang for your buck.

    If you're undecided, just STOP AND BUY IT!

    I've been researching and watching youtube videos for the past 5 months. I just recently said **** it and bought it. WOW! This thing is LOUD! Paired up with my Flowmaster American Thunders it sounds insane! But i'm going to be buying SLP Loudmouth's! Also please note: I do not have a intake/tuner. I am using this on 91 octane, Mobil 1 Full synthetic, and offroad x pipe with Flowmaster American Thunders! So far no check engine light, but for those of you asking, YES it is just fine to run an offroad x pipe without an intake and a tuner!

    Holy cow!!

    Jesus Christ! You hate your neighbors? Buy this. I don't think you'd need to spend $400 for an X-pipe since Pypes honestly makes some of the best ones around. The hardest part of the install is removing the stock H-pipe. I don't have a tuner but I can feel it pick up speed faster since it isn't restrictive and it weighs 20lbs lighter. Then comes the sound. The raspy, glorious sound. This isn't for the faint of heart. You don't buy this if you want a cool sounding daily driver. You get this X-pipe because you want to be the badass on the block. Thanks AM!

    Love it!

    Installed an intake/ tuner combo and my car seemed a little quicker, but after installing the X-pipe it was a whole different pull. WAY more mid-range and high-end power. My 2010 GT made 314whp/ 331tq with intake/tune/OR-X/ stock axle backs. Since then I've added Bassani Race AB and it sounds absolutely evil with the X-pipe. If you love raspy sounding exhaust I highly recommend this x-pipe.

    This product is great! Will need to tune for full benefit. If you really love your neighbors you WILL have to be easy on the throttle. Especially if you have headers and some aftermarket axlebacks. But I would let that stop you. No regrets whatsoever.

    The neighbors will hate you

    Easy install on my 07 GT. Only concern was the fit. Had to tweak the passenger side to fit properly onto the stock exhast manifold. But its an aftermarket part and if you've ever dont any other bolt-on goodness, you know that tweaking is normal. Was going to run it with no mufflers. But, It was go to jail loud. I put the stock mufflers back on, but it sounded exactly like flowmasters and every other mustang out there, not what I was looking for. So now the set up is the o/r x-pipe with cherry bomb glasspacks and I absolutely love it! Couldn't be happier. I don't experience the raspiness normally associated with x-pipes. The car absolutely screams at about 3k rpm, and there's no roar at highway speed. Has that old muscle car sound at idle. You will draw attention to yourself, everybody stares. I have yet to have any problems with the cops, and I've been running this setup for about a month and a half now. NOTE: Check engine light will come on, that is a given due to removing the cats (common sense really) Simply purchase a CAI/programmer package from AM and problem solved. And plus its a hell of a deal. I'd roughly say a 30+hp gain with the exhaust, CAI and programmer. Not bad for under $800. My father even likes the sound. And he's a tough man to please. He even jacked my car keys and took the Stang for a joy ride he liked it so much!

    Raspy Loud

    This X-Pipe alone is very raspy around 2200 - 2500 RPM. Install the high flow cats with this X-Pipe to get rid of the raspy sound. I coupled this X-Pipe with the high flow cats, Ford Racing headers, and 40 series Flow Master Mufflers. The setup produced a very clean rumble and the horsepower increase is noticeable.

You can really fool some people with this set-up, it really sounds like you have a big block under the hood. Great raspy old school muscle sound and good gains in mid and top end power.

    TRANSFORM YOUR CAR

    WOW. Bought from AM and pipe came in the mail about a week later. INSTALLATION: Had a shop install it, they said the install went great but they had to alter the pipe a tiny bit (bore a hole 1mm wider) to fit the passenger side O2 sensor in it, and that it was a bit of a reach. Not a problem though! Took 45mins to install with one mechanic doing it. Cost me 124 bucks at a high-end muffler shop. Before reading on, consider that I have Pypes Violator axlebacks. They're chambered mufflers, but they're high flow and loud. Not quite straight pipes, but close. Not as loud or raw as Pypes Bomb. LOUDNESS: This is LOUD! driving home from the shop I was scared to even let it above 2000RPM! Immediately turned heads everywhere I went. This is LOUDDD. You can creep quietly through a neighborhood if you have to, but if you need to accelerate.. game over.. haha.. Idle past cops. EXHAUST NOTE: Takes a bit of getting used to! After the drive home from the shop I sort of felt like I rap]ed my GT. This innocent pony was now snarling, screaming and growling as if it's mad at me... wasn't sure I loved it until I did some driving later that night...I fell in love with the sound. It's a challenge keeping the car quiet driving downtown and in neighborhoods, but I love doing it (saves me gas too, up 2 MPG). As soon as you add power, the raspy sound will come out at any RPM range. with full power, the entire band is LOUD and it opens up at about 2000, from 2000 to 3500 it gets a bit raspy, but as soon as you get it over 3500 it turns into a beautiful smooth tuned race sound. I love merging onto roads and watching other drivers faces when they hear it.. Oh, and when you start it up the hairs on the back of your neck will stand up. The sound itself is raw and raspy... but not in a bad way.. you can almost hear each cylinder fire, and it seems that having virtually the same flow out of each pipe allows this. If you don't love it at first, you will learn to love it. Goes very well with my violators. POWER: I don't even have a tune for it yet (waiting for tuner in mail) but the car breathes so much better above 4000. It reaches redline much faster. Definitely feel the horses. Pipe makes it sound like im packing 700 of em, too. BANG FOR YOUR BUCK: Absolutely. Everywhere you go, your car will turn heads. Floor it, and everyone in the town will be looking for the source of that great noise. Puts Lambos and Ferraris to shame ;) Girls love it, too. Also note that without the catalytic converters, your exhaust is quite a bit more smelly, and you'll often catch a sniff of it at a light or cruising windows down. Warning: This is loud. Scary loud and agressive. If you don't want your Mustang to sound like a 700hp race car, don't buy it. I hope this review helped! Thanks AM, you guys are the best.
