    • Raspy Race Car Growl
    • High-Flow Ceramic Catalytic Converters Included

    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 inch 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.

    Application Note. 2004 Mustangs require the use of 24 inch O2 sensor plug-in extender wires.

    Technical Note. This Magnaflow Catted X-Pipe is not legal for use in California or other states adopting California emission standards.

    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

    • 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.

    Have an O4 Cobra Stock Headers and magnaflow catback with an offload H pipe and stage 3 comp cams and wanna tone it down since its a bit too loud will these high flow cats clog or be blown with my mods?

    Is this CA legal ?

    • The Magnaflow Catted Tru-X X-Pipe has not be tested or approved by the California Air Resource Board (CARB) meaning this is not legal for use upon highway in the state of California.

    I saw a review this was paired with the Borla Ataks. Does anyone know if that setup requires modifications to anything or is a direct bolt up?

    • The Magnaflow Catted Tru-X X-Pipe will bolt up directly to a Borla Cat-Back Exhaust.

    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?

    • If the Magnaflow Catted Tru-X X-Pipe is still rattling it could be something internally broken in the cat causing this sound yes.

      AWESOME SOUND!

      I paired this with a Borla Atak Cat Back and I can't be more ecstatic of the sound! Head turner! With this setup I did NOT need O2 sensor extensions on a 2003 GT Convertible. Also buy the Ford gasket for the right side. The one that comes with the kit is junk, but unlike Borla at least the included new bolts.

      Nice product

      This x pipe fit perfectly, hardest part was in plugging front O2 sensors. Also make sure you spray manifold flange bolts with penetrate oil, that will help a lot. I also did a magnaflow cat- back too. Sounds great!

      03 cobra

      I had stock manifolds and h pipe with Flowmaster catback. I added the Magnaflow X pipe and it really woke up the Flowmasters. Still great for a daily driver. Not too loud but a nice deep growl. Gives me a little more clearance underneath as well.

      An upgrade to my upgrade

      Much better than my BBK x-pipe which the cats failed early on me (only have 16,000mi on the car). The Magnaflow x-pipe sounds better and I have better torque throughout especially on the upper end. The Magnaflow bolted right up to the stock manifold and my Magnaflow cat-back system. O2 sensors swapped right out without the need for any extender adapters. Swapped pipe in my driveway after work one day using Jack-stands on the front end only. It took almost 3hrs to do the whole swap. Recommend a strong impact wrench to break the old nuts/bolts free. Also recommend have a friend give you a hand maneuvering the new pipe in place.

      Amazing sound!!

      Passenger side exhaust manifold gasket that came with kit only had one shoulder on it.. installed it and it had terrible exhaust leak from passenger side. Removed x-pipe and re-installed factory Ford manifold gasket that has two shoulders to seal and it worked perfectly.. im a senior master ford technician so I do this stuff for a living.. just a disclaimer if your gasket only has one shoulder on it.. don't use it.. sounds absolutely amazing and my cobra is lowered on HandR race springs and it tucks up nicely.. can feel the car pulling a little harder on the top end side of the RPM range.. the sound is a big head turner paired with my Borla ataks.. Thanks AM!

      Magnaflow tru catted X

      If your debating getting an aftermarket mid pipe this is the one. The quality of the x pipe is there. Made in America, great welds. Performance is up I put this on my 03 cobra and it really woke up the car gave it a much defining tone. This combined with the borla stingers is one of the best sounding exhaust set ups. Can't beat the high flow cats! No smell! More Power!

      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.

      Love it

      Paired this with the Bassani Cat-Back Exhaust and I absolutely love the sound. My car has been almost completely stock since I bought it in 2001 and the exhaust is one of the Mods I've wanted to make for years. Well, the wait is over. Brought the X-Pipe and Cat-Back to the local exhaust shop, took him a couple hours and I got a new car in return. Absolute joy to drive now, in fact, I find myself just hopping in and going for a drive all the time now. The one thing I have noticed is a little sputtering when I let off the gas but I'm assuming that is the Catalytic converters. Not a big deal. Also, a little pricey but worth it.

      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.

      Magnaflow catted x-pipe

      I had my shop install this x-pipe, and they ran into multiple problems with it. They had to modify the pipe and extend the passenger side of the x-pipe about 1.5-2'' in order for it to reach the manifold flange. Then on the same side, only where the x meets the catback they had to extend it another inch in order for that side to reach. Not only was it a pain for them to get the existing stock h-pipe off, but now I've got a leak and will have to take it back for more work. I do not recommend this product, and Magnaflow needs to check their measurements.

      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!
