Features & Details

  • Improves Exhaust Flow for More Power
  • Raspy Race Car Growl
  • High-Flow Ceramic Catalytic Converters Included
  • 2.5" Mandrel-Bent Stainless Steel Tubing
  • Fits 99-04 GT, Bullitt, Mach 1 and SVT Cobra
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 catted H-pipe.

Race Car Growl. This free flowing Magnaflow Tru-X X-pipe for the 1999 to 2004 4.6L 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 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 1999-2004 GT, 2001 Bullitt, 2003-2004 Mach 1 and 1999-2004 SVT Cobra Mustangs with either aftermarket short tube headers or the stock manifolds and a dual catback exhaust installed.

Note: Coupon codes cannot be applied to this product.

Technical note: 2004 Mustangs require the use of 24" O2 sensor plug-in extender wires.

Is a tune required when replacing the stock cat system? I am thinking of replacing the stock catted system with a Magnaflow catted X-pipe set up. Is a re-tune required with the new system? Thanks. Dick

Cobradriver

  • No. You don't have to do a tune for the exhaust system. Now if you were doing headers and a full system with a cold air kid I would advise it because you will maximize you upgrades that way, but if your just putting on the xpipe you don't need to.

I bought a low mileage used 2003 cobra with this x-pipe system installed and a Bassani exhaust system. The right cat heat shield tack welds were partially broken causing a low RPM rattle. External appearance looks like the cat scraped a speed. Safety wiring the heat shields reduced the rattle sound but did not eliminate it. Could the internal cat ceramics be broken?

JimB

I have a 2003 new used cobra with this system installed. Will this system mate up with JBA shorty headers if I decide to replace the stock headers?

  • This mid-pipe will bolt up to any shorty headers yes!

which is better h pipe or xpipe

ArthurW

  • Crossing over in an "X" shaped design, X-pipes typically are a bit louder and produce slightly more power later in the RPM band than an H-pipe An H-pipe produces a classic muscle car growl and will boost torque lower in the RPM band.

Has anyone run this catted magnaflow x-pipe with the stock catback ? Interested in how much louder it makes it.Specifically at cruising speeds.M car is an 01 GT convertible which the wife drives 100 miles daily.Loud is not good for wifey.

Stroker

  • The Magnaflow Catted Tru-X X-Pipe will definitely be an increase in volume form the factory setup. It is difficult to rate on a scale exactly how much louder it will be. I would recommend looking up some sound clips on a website like youtube.com of other mustang enthusiasts with this setup on their mustang.

From 4 to 6000rpm the engine can breathe and you will feel the car pull harder. Magnaflow has great quality, easy install as the X-Pipe matched up. Did not need an exhaust gasket on the left side as the stock unit is steel and worked without leaks.

    Perfect Fit Catted X Pipe

    Hi, I just wanted to give my opinion on this catted X pipe. I have a 2001 Mustang GT with an automatic transmission. This item bolted up perfectly to my stock exhaust manifolds without any problems. Ground clearance was a little better than stock and it tucked up very nicely to the floorpan without and rubbing issues. To save yourself any frustration or headaches, remember to purchase a passenger side exhaust manifold flange gasket. Some people might say that you can reuse your old one but, why take a chance on a possible exhaust leak. In my opinion, the best one is made by FelPro and the part# is 61203. As far as installing this item in your garage or driveway, it can be done but there is no way you`re going to be able to properly align and tuck this item up high enough using ramps or 2 pair of jack stands. Also, removing the passenger side upstream 02 sensor and H pipe to exhaust manifold nuts are not for the faint of heart so be warned. Just budget another 50.00 - 100.00 dollars to have a local exhaust shop install it for you if you don`t want to tackle this install yourself. My shop knocked it out in 40 minutes and the cost was 75.00 Keep up the good work American Muscle.

    x pipe sounds great

    x pipe sounds great easy to install and i really think becuse of the x under the trans it helps to warm my t3650 for better shifts i think so.tech note the parts store gasket requiered for the rt side that i purchased did not look like it would seal as good as the gasket that came with my bbk shortys so i reused that old gasket and i dont seem to have leaks so far the parts store gasket had crush bump on only one side as apposed to the bbker having both sides bumped.

    Catted X-pipe

    I installed my Magnaflow catted x-pipe about a week ago and the exhaust tone is quite a bit more aggressive especially partnered with my Borla stingers. Here soon i need to adjust it to get a slight leak out, but it was probably my fault. I cant wait till the carbon builds up and get to hear the real potential of this x-pipe. I first drove it with my 200lb and 300lb friends in the car and it almost was as quick as it was before with just me in the car! I felt a great increase in power especially when i hit 4000 rpm. it rips!! Thank you AM you never let me down

    Sounds so nice! "but"

    Got this in a while ago and finally had it installed on 03 GT 5 speed! Top Quality stainless steel construction! Only drawback is M Flow does not include gaskets! Had it installed w/o them and had no leaks after blowing smoke at the collectors! However, there is a rasp and mild exhaust odor coming out of engine bay! Don't know why! But, passed PA emmission, no check engine light, (could be due to MIL eliminators though) & good sound! Save the fustration and get gaskets just in case! Mated to F Master cat back very well after some pulling and tugging & no welding needed!

    Review with stock cat back

    I installed this while leaving the mufflers/tail pipes stock.Not much louder on startup,idle,and steady cruise.You can tell it when you floor it,especially above 4000 rpm.It changes the tone even with stock mufflers.Doesn't compliment the stock muffler sound IMO but I am looking for "quiet" power as my wife wants it that way.She probably won't even notice it and I didn't tell her I installed it. I plan to add either the Dynomax super turbo or the Summit brand polished stainless (straight through perforated tube) mufflers for minimal loudness.I have used them both before with minimal drone/obnoxious noise.

    Great Sound and noticeable increase in power.

    I purchased this for my '03 GT. Whoever owned the car prior to myself, removed the cats from my old pipes. Upon installation (done by a local Ford shop), the car sounded just as mean as it did prior to, but a bit cleaner note. As stated in prior reviews, upper RPM power increase is immediately noticeable. My 'stang pulls harder and seems to run so much smoother with this installation. Yet another great American Muscle order!

    They Hear Me Now

    Loving the deep tone. This X-pipe has been installed for about a week and does she sound great. My exhaust set up consist of stock headers, magnaflow catted X-pipe (this product), and chambered magnaflow catbacks. Great deep note at idle and good rumble while at cruising speeds. Haven't been able to go WOT due to me in the stages of breaking in a new Mcloed clutch. Few hundred more miles to break-in and we will see what she can really do. You will love this product, no buyers remorse. Be sure to purchase the O2 sensor extension cables, had to do some modifications to my wiring sense I didn't purchase them. Considering upping my fuel injectors to 24 lb/hr by Ford Racing. After this install I get the feeling my pony is starving for fuel, seems to lag when approaching hills. All mods consist of KandN CAI, 70mm TB, Intake Plenum, SR Coils, and Bama Tune. Thanks American Muscle.

    Off Road Only

    Pros: This exhaust made a drastic change in the exhaust note of my 01 GT. It added a much deeper and more aggressive tone that you cant help but show off at red lights. The performance is definitely noticeable with an increase in throttle response. Cons: I wanted to put down the extra money to have a catted pipe, because i wanted to keep my exhaust system street legal. When i received the x-pipe it states on the cats "off-road only". I was a little disappointed, but it was worth the investment. Still passed inspection though

    Magnaflow Catted X and SLP LM 1

    I've had this particular combo for about 8 years now on my 2002 GT vert. Well, after all this years it finally gave up the ghost when the driver's side cat started rattling. I'm quite sure it would have lasted much longer but a lowered car, speed bumps and one or two road gators took it's toll. I toyed with the idea of going with another catted x-pipe but decided to stick with what I was absolutely satisfied with. It carries a premium price but you get every bit of what you pay for. Solid one-piece construction, mandrel-bent stainless steel with OEM fit and the sound is pure road music. Would I do it a third time? You betcha!.

    Another great product from Magna Flow. This catted x pipe is well put together. It is solid, yet so light weight. With a tune for the high flow cats, it definitely had a seat of the pants feel. The exhaust sound does turn heads. Did not have any check engine light problems! Thanks american muscle for this great product and quick shipping!
