  • Improves exhaust flow for more power
  • Raspy Race Car Growl
  • High-flow ceramic catalytic converters included
  • 2.5" mandrel bent stainless steel tubing
  • Fits 2005-2009 GT and 2008-2009 Bullitt's
Improves Exhaust Flow. Magnaflow's X-Pipe uses free-flowing mandrel-bent piping with a Tru-X "X" style crossover and high-flow catalytic converters to improve exhaust flow and to produce significantly more horsepower and torque at the rear wheels than the restrictive stock factory catted H-pipe. Race Car Growl. This free flowing Magnaflow Tru-X X-pipe for the 2005 to 2009 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 2.5" mandrel bent stainless steel tubing that has a consistent diameter throughout the length of the pipe, even at the bends to provide excellent exhaust flow that results in more power at the rear wheels. The included high flow ceramic catalytic converters far out perform the restrictive stock factory cats to provide a significant increase in horsepower and torque.

Application. This Magnaflow Tru-X Catted X-pipe is designed as a direct bolt-on for the 2005-2009 GT and 2008-2009 Bullitt Mustangs with either aftermarket short tube headers or the stock factory manifolds and a dual catback exhaust installed.

Just got it installed today. I took the car to a shop to combine this and the Borla S Cat-back. The installer said it went together with little trouble. At idle, this combination isn't going to piss off

Is a tune required?

  • A custom tune is not required when installing this Catted X-Pipe. It will, however, offer you optimum performance gains by combining this mid-pipe with a tune.

Long Tube Headers? Is there any way to hook a long tube header like the kooks or pypes products to the magnaflow catted x pipe? Would cutting or welding be necessary or could you just bolt right on?

    Just got it installed today. I took the car to a shop to combine this and the Borla S Cat-back. The installer said it went together with little trouble. At idle, this combination isn't going to piss off the neighbors - Pulling away from the house, especially if I'm in a hurry - is a very different story! It growls with a lot of authority and is an absolute joy that only increases with the RPM's. Combined with C&L Racer CAI, SCT X3, Steeda underdrive pulley, Steeda Tri Ax shifter and Motive 3.90 gears, I couldn't be happier with Phase I. All these components work well together and there will be more to follow - and American Muscle will fit in big in future plans. Thanks!

    Sounds great, no gains.

    November 14, 2009

    On my naturally-aspirated Mustang GT, dyno testing showed no gains in HP or Torque vs. factory H-pipe, but it sure does sound great.

    Great sound

    April 09, 2013

    This product sounds amazing. I have it paired with the Flowmaster outlaw series muffler. I selected afternoon only because I ran into a problem taking the old ones off, otherwise it would have taken less time. The x-pipe looks very nice. The only thing I was confused on was that there was a metal plate spot welded on the converter that says off road use only. Great product for the money.

    love it!!!!

    July 06, 2011

    The install was easy on a lift. I was gonna do it on the ground and decided not to. Glad i did cause it would have been a pain on the ground. I love the growls sweet in between shifts and top end its awesome. I have flowmaster american thunder mufflers and the sound cant be beat. I have steeda cai, sct sport tune, steeda underdrive pullies, hurst comp plus shifter, bbk 62mm t-body and the one piece alum. drive shaft found right here in american muscle and im running 12.88!! Not too bad for a daily driver!!!

    I had Borla stingers and they sounded awesome, but this x pipe made them sound even better. Also, I dont have to worry about emissions with the cats.

    Nice Sound

    June 08, 2011

    Awesome sound, fairly easy install, a little tweaking to get the tips lined up perfectly though. The pictures on the web site do not show that it comes in 3 pieces and you have to use the provided clamps to install.Cannot complain about the price as it was 62% off, but is still fairly high priced compared to others on the market. I would not have paid the 1500+ bones reg price.Also kinda disapointed they was no sticker included in the box, even though I would not stick it anywhere on my car, it's nice to have. You cannot beat that sound though, above 3000 its like music. Paired with a set of Roush cat-backs its absolutely sweet!!

    Great addition to my 2009 Bullitt. I chose to go with thia x pipe because 2 of the 3 mustang places recommended it over all other catted x pipes. I also like that i dont have to worry about emissions and the high flow cats make it sound chrisper. The installation was easy with no modifications or leaks. Also the 4 inch tips look great because they are stainless and no rolled like a lot of the others. I chose this x pipe with the magnaflow axleback with magnapack straight through mufflers and it sounds amazing. I just have a some drone from 1800-1900 rpm but it doesnt really bother me. I also like that when you're cruising there's a nice intimidating rumble but if your putting around or taking off slow its not obnoxious but its very loud once you hit it. It turns heads and it is a must for the person looking for a great all around exhaust.
