Description
Improves Exhaust Flow. Replace those power robbing factory catalytic converters and release hidden power with a Magnaflow Off-road X-Pipe. Featuring a Tru-X "X" style crossover and free-flowing mandrel-bent piping, this high performance x-pipe dramatically improves exhaust flow. Magnaflow's Off-road X-pipe out performs the restrictive stock factory catted H-pipe by producing more horsepower and torque at the rear wheels. Race Car Growl. This free flowing Magnaflow Tru-X X-pipe for the 1999 to 2004 Mustang's not only increases power, but with its modern "X" crossover pipe design it also adds a crisp raspy, race car growl to the sound of your exhaust.

Magnaflow High Flow Construction. Magnaflow uses free-flowing 2.5" mandrel bent stainless steel tubing that has a consistent diameter throughout the entire length of the pipe, even at the bends to provide excellent exhaust flow that results in more power at the rear wheels.

Application. This Magnaflow Tru-X Off-road X-pipe is designed as a direct bolt-on for the 1999-2004 GT, 2001 Bullitt, 2003-2004 Mach 1 and 1999-2004 SVT Cobra with either aftermarket short tube headers or the stock factory manifolds and a dual catback exhaust installed. Intended for off-road, track use only, does not include catalytic converters.

Technical note: 2004 Mustangs require the use of 24" O2 sensor plug-in extender wires. This Magnaflow product is intended for off road use, and is not legal for use in emission restrictive states.

Awesome with SLP Catback

I had this Offroad Xpipe on my 2004 Mustang GT along with a SLP LM1 Catback and you could literally wake the dead. Dogs would bark and then take off running, birds in parks would take off flying, old neighbors

Do i need mil eliminators if i have a bama tune?

  • Nope! The MIL eliminators turn off your CEL caused by installing an off-road mid-pipe. If you have a Bama tune that encompasses this mid-pipe, you wouldn't need to purchase the MILs.

what is the mil eliminater? i want to buy an x-pipe but dont have a tune will the mil eliminater keep me from getting a check engine light?

  • That's exactly what the MILs are intended to do. Due to removing your cats, the MIL eliminators will turn off the corresponding CEL! I highly recommend a custom tune down the road though as it will help you see the full potential of the mods on your Mustang!

    I had this Offroad Xpipe on my 2004 Mustang GT along with a SLP LM1 Catback and you could literally wake the dead. Dogs would bark and then take off running, birds in parks would take off flying, old neighbors would shake their canes. Excellent product, fit and finish was top notch.

    Get the most out of your Mustang with the Magnaflow Tru-X X-pipe!

    November 04, 2011

    Get back those wasted horsepower by getting rid of your catalytic converters! The Magnaflow X-pipe replaces the stock mid pipe and is an easy bolt-on mod that gives your Mustang more horsepower and allows the engine to breathe easier. Without catalytic converters hindering your engine's performance, it can also produce a very aggressive race car growl. Don't bother with multiple piece and clamped mid pipes that leak and cause issues. The single piece Magnaflow is very simple to install and bolts directly to your exhaust system. Be sure to get a set of plug-in MIL eliminators to keep that pesky engine light off as well as the 02 sensor extension kit if your Mustang is a 2004 model. The Magnaflow Tru-X X-pipe is one of the best and easiest modifications you can do to add horsepower and a raspy growl to your Mustang!

    Tru-X

    June 13, 2010

    I really enjoy the sound that this produces without cats. When AM says it is a Tru-X it is. Fitment is amazing and the Power is there. On a Cobra Mustang it sounds mean. I would highly recommend this product for no leaks. i got rid of of Bassani because it leaked so bad. Great Product AM!!

    Very quick install time. Took me a about 2 hrs, including the time for cool down and an oil change. Did it by myself too. It does state it comes with everything, however mine did not come with a passenger side manifold to x pipe gasket. I was able to reuse the old one however. Sounds so much better and runs better too.

    The cats on my stock midpipe must\\\\\\\'ve been partially clogged because I am now getting a lot better mileage with this o/r pipe and the Magnapacks. My exhaust is much louder now.

    Don't buy the Pypes

    May 14, 2011

    Just installed this pipe on my stang. Replaced the Pypes O/R X pipe I bought here a year ago. Leaking beotch. As soon as I took this Magnaflow out of the box, it screamed quality. Ever hear the expression, you get what you pay for? Well, this is no exception. My Pypes pipe was a constant leaker. Up in air multiple times and even to the exhaust shop multiple times trying to get that piece of crap to stop leaking. Like a monkey bent the tubing. This pipe practically floated right into place. The sound is a tad louder than the Pypes and really wakes the dead. After installing the Ford C-Springs, and this X-pipe, paired with my Borls stingers, I went for a ride. About 9pm. Thought I would let ol'lady and kids hear the new exhaust. Pulled nice loud burnout in front of my place in real quiet neighborhood. Then straight to garage to pack up for the night. Man, it didn't take long before the cops were cruising the neighborhood. Neighbors better get used to it. Sounds too damn good. Worth every penny.
