Improves Exhaust Flow. Ford actually did a nice job on the S197 Catalytic Converters, but the stock H-pipe could use some improvement. That's where the Ford Racing Cut and Clamp X-Pipe comes into play. Designed to balance out the exhaust gas pressure in your system, this X-pipe will help improve exhaust flow for more power and sound.

Reuses Stock Cats. The installation of the Ford Racing Cut & Clamp X-pipe requires cutting and removing the stock H-pipe, and reuses the factory catalytic converters saving you money. Clamps and instructions are provided.

Quality Materials. Constructed from sturdy 2.5" mandrel bent T-409 Stainless Steel tubing the Cut & Clamp X-Pipe will improve exhaust flow and last a lifetime.

cat or no cat I was wondering if this x-pipe will work with and/or without a cat? And if so, how difficult would reinstallation of the cat be? What would be involved?

    Great sound.

    Thought about installing myself but wised-up and glad I did. Had a muffler guy do it cause he has the right tools (lift) and it took less than an hour and less than fifty bucks. Sound is great. Took away some of the drone from my Ford Racing Borla Stingers and evened out the tone. All went together well after loosening front of exhaust at the manifold.

    Not what I was advised...

    This is a good product to free up exhaust flow and get rid of that stock H Pipe. I can not say that it made any real difference in HP or throttle response as opposed to the stock. My main reason for the purchase was to see if it would help tone down some cabin noise in our '06 Conv we have had since installing the Borla Stinger mufflers. NO, it made no noticeable difference at all. So depending on why you are considering this purchase for- That $125 bucks would probably go better towards a full catted or off road X Pipe (depending on your prefrence) if you are looking to really free up exhaust flow; OR put it towards a more subtle muffler like Borla Touring or FR Bullitt if the Stinger mufflers were more than you wanted (having regreted the purchase after installing them and going deaf after a ride down the interstate). **Live and learn- or learn from my trial & error. The team at AM were helpful- the X pipe arrived in a timely manner, and the pipes were installed by a local shop. I hope this review was helpful.

    Sounds Great

    A bit of a PITA to install. Best to mark the head pipes and cut them on the car. Then remove them to install the X on the floor. The angles make getting it on a real challenge unless they are removed. The clamps are first rate as is the construction of the pipe. Changed the exhaust note quite a bit. Bottom it!

    less burble - more snarl

    The X-pipe was an easy install. I do notice that the vehicle is more quiet at idle but has a more snarl in the exhaust note when getting on it. I don't notice a performance change in driving it based on seat-of-the-pants feel. Highly recommend to anyone due to ease of installation.

    frpp xpipe

    this x-pipe is great. makes a very noticable change in tone and volume of the exhaust. install is kinda hard. cutting the pipe is a pain if you are doing this using jack stands. and getting the new pipe to slide over the old pipe can be hard since not all bends on either pipe are exact. but once its on it is the sound makes it worth the minimal cost of time and part

    very happy with results

    I never quite understood the rational of switching from H pipes to X pipes, but enough people I trust said it was worth it, and they were right. Everyone has different setups, so improvements I'm sure will vary, but when I pulled off the line right after these were installed, my tires screeched with just a touch of the accelerator. The products in the box are top quality, and it looked like a very simple installation. But as I get older (lazier) I like less and less to crawl under a car, so I had a professional install them. It cost me $50 and took less than 30 minutes. So, for a cost of under $200, I have a great product, more acceleration, and a smoother sounding exhaust. I have absolutely no complaints.

    X pipe

    I agree with the previous post. Once you get it to fit over the original pipe it is best to hit it with a hammer and block of wood to get it tight. Cutting the old H pipe off was easy with a reciprocating saw, metal cutting blade and some WD-40. Measure twice and cut once. The clamps are 1st class. A lift would be nice as well if your a big guy.

    Ford Racing Install Illustration Misleading

    At freeway speeds, the X-pipe dampers much of the harsh in-cabin mind-numbing drone of the after-market axelbacks, especially between 1600-2000 rpm. And, while downshifting the five-speed and at idle, the exhaust tone is now a powerful pulsing rumble; the "burble" is gone. I only give it three stars for "fit." Although the supplied clamps are first-rate, as is the X-pipe itself, be prepared to remove the forward exhaust system from the exhaust manifolds: there is no good way to "fit" the X-pipe onto the new pipes ends you just cut without doing so. Beware, unless you have magical installation elves that come into your garage when you're asleep, do not be deceived by "Fig. 12" in the Mustang X-Pipe Instruction Sheet. I installed the X-pipe with my car on jack stands and my back on the garage floor. To give myself extra room to fit the right-side of the pipes, I temporarily removes the thin aluminum heat shield. After much trial-and-error measuring to roughly align the pipes to their original orientation, I loosely clamped the X-pipe to the now-removed front pipes, placed this new assembly, and myself, under the car, carefully hoisted it up above my head and gingerly hooked it into the two rubber isolation mounts. With a lot of twisting-and-fitting, each pipe end lined up with its exhaust manifold, but not at the same time! Together, the pipe ends were spread approximately two inch too wide. I used a ratcheting tie-down strap to slowly pull the two pipe ends together to the correct width, bolted the ends to the manifold, clamped the loose rear pipes onto the X-pipe, tightened all four clamps, then released the tie-down strap. The pipes fitted perfectly, with no exhaust leaks. I'm glad that I installed the Ford Racing X-pipe -- it reinforced the benefit of doing push-ups. The exhaust system seems to breath easier. But frankly, knowing what I know now, for ease of installation, I would have preferred the Pypes X-pipe that has built-in straight sections and mounting hooks. Pypes doesn't require the disassembly and removal of the front end of the exhaust system (and I won't even discuss the ordeal of disconnecting and reconnecting the passenger-side O2 sensor cable!). This installation would be a lot easier using a lift (but not by much).

    Very Nice

    I bought this pipe because I wanted to step up my exhaust, but I wanted to stay with Ford Racing parts. The install is simple, but annoying because there's not a lot of room to work with the car on jack stands. A saws-all cuts through the pipes like butter. The X is a tight fit over the existing pipes, but stay with it, it'll go. Once it's all bolted up, it looks clean; pretty much stock. I have an 09 Bullitt which come with a washer welded in the middle of the stock H, in order to obtain the sound from the movie. Basically, the stock H on an 08/09 Bullitt only has about a 1/2" hole inside. The sound is a bit quieter, but the car is also a bit faster. It feels like it may have lost a little on the bottom, but it definitely has more power in the upper RPMs. I bought a set of FRPP shorties as well, and I will be installing them this weekend. I'll post a review on those as well, but I'm expecting them to deepen the tone and really work well with this X.

    I love the way it made the car sound. Also my throttle responds has improved hardcore. My only complaint with these is they didn't fit..they had to be heated up and bent to fit better. Besides that they r a decent product

    Nice End Results Very Fun (not) Doing it On Jack Stands

    Just finished install on a stock 2008 Base model GT. American M. instructions and Fords are both available on AM site. There was a small measurement difference between the two. Although I checked the Ford instructions, I followed AM instructions. The job was difficult due to working up and down on your back wrestling with the pipes. ....but its a "hobby". * The fit to the head pipes was difficult but it can be done (without removing the head pipe)s. An Irwin grip 600 LB set up as a spreader to spread the head pipes just gave me the angle needed. AM instructions say to use a ratchet strap to draw the head pipes together. It was a spread first in my case. Recommend this item. No dramatic change in sound (felt smoother? ) but a nice throttle response difference from stock. Now need a pair of mufflers and an AM discount code. THX.
