Description
Upgrade To A True Dual Exhaust. Now you can easily upgrade your V6 Pony to a true dual exhaust with a Pypes Catted X-Pipe. Just install this Pypes X-pipe along with the 1999-2004 GT catback of your choice, to give your Mustang the impressive looks and sound of a GT.

Balances Exhaust Gases. This Pypes catted x-pipe balances out the gas pressures in your exhaust system to create more power and torque than a traditional H-pipe. Why? Because the exiting exhaust pulses are merged at the "X", resulting in less exhaust back pressure for more power.

Modular Construction. Pypes unique three piece modular construction makes it quick and easy to add or remove a catalytic converter to your exhaust system in just minutes depending on your driving needs.

Durable Stainless Steel Construction. Pypes uses sturdy 16 gauge 409 stainless steel mandrel bent 2.5" tubing for improved flow and features welded reinforcement plates for additional strength. The included Catalytic Converters are build from polished 409 stainless and feature a durable Ceramic substrate material making them perfect for naturally aspirated applications.

Application. This Pypes Catted X-Pipe is designed for use on a 1998-2004 V6 Mustangs in combination with an aftermarket or stock factory dual 1999-2004 GT catback exhaust system.

Technical note: Must be used with a stock or aftermarket GT catback exhaust system!

    Great Sound; Tough Installation

    First off, GREAT SOUND ON A V6!!! I installed this pipe (with cats) this past weekend along with BBK chrome shorty headers and a Flowmaster American Thunder Catback with Super 40 Series mufflers. I never thought my 6 banger could sound this great. The shipping was fast, and I got everything AM promised me. Unfortunately, I had problems installing the x-pipe, and this is the only reason I am giving it 4 stars instead of 5. It took two other guys and myself about an hour or so to get the pipe to line up and slide the cats and pipes together and get the clamps on. Either take your car to an exhaust shop for the installation, or be ready to wrestle with it for a while. Also, after you get all the pieces together MAKE SURE you put a floor jack under the x-pipe and lift it up before you tighten up all of the bolts, or you'll have some SERIOUS clearance issues (I didn't do this at first, and I only had about two inches of clearance). After all is said and done, I am more than happy with the sound and performance coming outta my car. My dad and uncle could not believe it when I showed them my car. We put it next to my dad's 96 impala SS (has an LT1 V8 and flowmaster exhaust) and my v6 is louder! Thanks AM.

    BUYERS BEWARE!!!!!!!!

    To start American Muscle is awsome and there customer service is great. Pypes on the other hand is very bad. I had bought the catted X-pipe back in march 2009 with an SLP setup. The mechanic I payed to put it on had a tough time getting the X-pipe to fit and he barely got it on. In April of 2010 my check engine light came on and was told that I needed to replace an oxygen sensor. It is know February 2011 and I replaced my oxygen sensor, but my check engine light is still on and the real reason its on is that one of my catalytic converters is bad. With the catalytic converters being under warranty still (5 year warranty), I called Pypes. I told them the problem and they said they would replace it all I had to do is Email them my order invoice and phone number and they would mail me a new one for $15.00 shipping cost. That was 3 weeks ago and I sent them 20 Emails and have tried to call them about it and the person on the other line keeps giving me the run around. I did finally get a hold of someone yesterday and they argued with me that I had to send them the defaulted part before I get a new one. But my main concern was that he told me, "The ceramics inside the catalytic converter's ware down after a few years and its normal." I of coarse would never had bought them if I'd known that and know I'm just trying to warn people about there horrible buisness. I am not going to put some crap on my car and am ordering SLP cats instead. Pypes is a terrible company so buyers beware.

    Installation Issues

    This is my experience when installing it on a 200 Mustang GT Convertible with stock manifolds. The product itself is well constructed and fairly easy to install. There are a couple of issues worth mentioning though. First off even if you install the included downsized flange on the driver side when installing this kit. On a stock exhaust you will experience leaks! I tightened it with a two foot breaker bar until my insides were about to pop and still had a leak. The problem was resolved by my going to a local muffler shop where they found that the factory studs have a fixed spacer preventing the pipes from fullly sealing correctly. They had to remove the factory studs and put in standard studs. Which incidentally cost me $100.00. Finally my car stopped sounding like it was ready for nascar. The second problem is with the placement of the gasket on the passenger side. Initially everything was fine, but after two weeks of driving and some of it was quite spirited. The passenger side started leaking making my car sound like I'm ready for nascar again. What I did to resolve the problem was double up on the gaskets on the passenger side and tighten it with the same two foot breaker bar. So far so good but we'll see how long it stays quiet. Don't get me wrong I do enjoy the nice sound of a performance exhaust, but not when it sounds like open headers and the cops keep pulling me over for violating the local sound ordinance.

    Sounds Sick

    THE SOUND IS AWSOME, INSTALLED IT WITH CATS AND STILL SOUNDED GOOD, NOT SURE IF IT WILL PASS SMOG SENCE I LIVE IN CALI. THE HARDEST PART WAS REMOVING THE STOCK Y PIPE AND THE O2 SENSERS WHERE A B!%#H, AND MAY BE ITS JUST MY STANG, BUT THE LOCATION WHERE THEY PUT THE O2 CONECTION WAS OFF BY 2-3 INCHES HAD TO BUY O2 EXTENSIONS TO GET A GOOD FIT, ITS EASYER IF YOU CAN GET YOUR STANG HIGH ENOUGH TO WORK BETTER UNDER THE CAR, OTHER THEN THAT SOUNDS AWSOME, OK QUALITY, GOOD PACKAGING, AND GREAT SHIPPING FROM AMERICAN MUSCLE.

    Sounds Like a GT

    This sounds almost like a GT nothing will ever make a 6 sound like an 8 but it is louder at idle than my friends GT with Magnaflow exhaust cat back.

    Awful Fit

    This thing fits horribly. The downpipes are too long, The flanges don't fit snug to the header flange, The X section doesn't line up with anything, and without using a lift to install it you're almost guaranteed sagging. Would strongly recommend finding another solution before using this midpipe.

    2004 V6 pony

    I would like to thank AM for distributing this package as quikly as possible. Pypes will deffinetly need to roconfigure the manufacturing fittings for this product. The piping the connects to the headers sre too long. maybe they sould shorten them and extend the x-pipe for tighter flush against the under carriage keeping the car from scrapping. I did all the work myself and now I will have to take to garage for all the loose ends.

    X-Pipe

    I had a local shop install. I already had a flowmaster 40 series dual cat back exhaust, but only had a y pipe. By adding the x-pipe it increased the flow and now it has a nice growl to it. It sounds awesome but by no means does it sound like a V8 but I'm happy with the great improvement in sound and horsepower increase.

    Great sound

    I was pleased with the Pypes X pipe, however, the install was tedious and more time consuming than I thought it would be because I had to cut the driver side down pipe so the mid pipe would fit onto the cats. Once I finally got the welds finished it sounded even better than my catted straight pipes though (made my 3.8 louder than a V6 should be).
