    Features & Details

    • Balance Out Exhaust Gases for More Power
    • Pypes Modular Construction
    • Catalytic Converters Included
    • 2.5" 409 Stainless Steel Tubing

    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 factory dual 1999-2004 GT catback exhaust system.

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

    if i add pypes catted x-pipes can i install flowmaster thunder catback with it

    • Definitely! This Catted X-pipe combined with the 99-04 GT Flowmaster American Thunder Catback would work great together. As a side note, this mid-pipe will allow you to install any 99-04 GT catback of your choice. Hope this helps!

    I have seen this X-Pipe (XFM39) listed on other sites to also fit a 1996 V6. Is this the case?

    • Unfortunately, this Pypes Catted X-Pipe is specifically designed for use on 1998-2004 V6 Mustangs and will not fit a 1996 V6.

    I have the flowmaster 40 series dual exhaust installed, will this x-pipe work with my setup?

    • The Pypes Catted X-Pipe will not fit on the Flowmaster force II exhaust as this would still be the Y-pipe and would not connect to the X-pipe.

    If Mac boom exhaust for 1998 v6 and this x pipe, do I need to use the cats that come with the x pipe? Or can I go without? What would that do if I did?

    • The Pypes Catted X-Pipe can be used without cats, however it would be better to use the Pypes Off Road X Pipe if you did not want to use cats. Not having cats will set the codes P0420 and P0430 for catalyst efficiency and will cause you to fail emissions testing, however it will provide additional power and torque gains.

    does this system come with the sleeves to insert in the pipes to connect them to the heads on a v6 like it shows in the installation write up

    • The Pypes Catted X-Pipe for a 98-04 V6 should include the required (2) small sleeves for both mounting points at the headers.

      Its alive

      Had it installed by my good friend Mingh at meineke along with the high flow cats and 2 flowmaster super 44s. For under 300$ and less than 3hrs. The O2 extensions were needed. Sounds great, loud but not overly. So my cars running 2.5 inch tubing from downpipe to xpipe all the way to catback with 3.5 inch tips.

      Night and Day: The difference is incredible

      Before I begin, I'd just like to say I was able to try this X-Pipe without the cats. One of the benefits was that the exhaust was louder. Let me tell you... IT WAS TOO LOUD. The X-Pipe without the cats was so loud, I was afraid to hit the gas pedal. It was insane. The exhaust note without the cats didn't sound bad, but it was unstable and out of control. The sound was too broad and overwhelming for my taste. Going by cops wasn't fun either because it makes too much of a scene and they will ticket you. Once I put the cats on, the exhaust was PERFECT. The sound and pitch was controlled, and the volume was silenced just enough. Trust me, this exhaust wont be quiet with cats on (I do have straight mufflers with the X-Pipe so this may have an effect whether or not you want cats or not). The throaty vibration makes the V6 sound amazing. It doesn't sound closed and it sure doesn't sound narrow. It brings a very pronounced articulation to the road. Performance wise, the X-Pipe makes the V6 really become another kind of pony. If you have a need for speed, the X-Pipe is just for you. It's MUCH easier to go fast especially at higher RPMS. The Y-Pipe struggled to hit higher speeds, but this X-Pipes thrives in doing so. The sound this X-Pipe makes compared to the Y-Pipe is unbelievable. It's much more aggressive and definitely has a true racing vibe. The X-Pipe really blows away the Y-Pipe in comparison to sound, performance and style. It's just better. Period. #NoRegrets

      Pypes X pipe cat system

      Must say that The Pypes set up is with out a doubt the best exhaust System on the market for the 3.8 liter V6 in a Mustang. I also bought BBK Shorty Headers that this bolted right up to. It is full 2 1/2" system with no restriction and I exited into Borla mufflers true dual system together with cold air intake system and MSD Ignition Brick my v6 Stang Rocks!!!

      Good quality

      I put these on my 2000 v6 Mustang. I did it up on ramps, actually a pretty easy job with the right tools. Only hard part is my manifold bolts stripped so I had to buy a reverse spiral socket for stripped bolts and it worked like a charm. I paired this up with the sr performance catback exhaust. It is now really quiet. It looks amzing though. If you're thinking about buying it then go ahead. Highly recommended.

      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).

      Pypes Catted X pipe (2000 mutang V6)

      This product was a great addition to my V6. It sounds great and I believe it will sound even better ounce I install flowmaster mufflers. Aside from the sound, it gave me greater acceleration than the y pipe which it replaced and, it did not need oxygen sensor extentions when installed everything fit like a glove! I would and have recommended this product, as well as, other products I have purchased from Americam Muscle!

      true dual pypes exhaust

      I've been wanting to add a custom exhaust system to my v6 mustang for a long time now. I probably spent over half a year reviewing my different options, but when it came down to it the pypes dual catback exhaust along with the catted x-pipe converstion system for v6s was the best solution. The sound is loud and crisp, about as close to a v8 as I could get and that was exactly what I was looking for. I highly recommend it!

      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.

      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.

      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.
