Features & Details

  • Balance Out Exhaust Gases for More Power
  • Raspy Race Car Growl

Balances Exhaust Gases. The Pypes Catted X-Pipe is excellent when it comes to balancing out the gas pressures in your exhaust system. This Pypes x-pipe creates 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.

Race Car Growl. This free flowing Pypes x-pipe for the 1979 to 1995 5.0's not only increases power, but it also adds a raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design.

Modular Construction. Pypes unique three piece modular construction makes it quick and easy to add or remove catalytic converters 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 exhaust flow and features welded reinforcement plates for additional strength. The included High flow catalytic converters far out perform the restrictive stock cats to provide a significant increase in horsepower and torque.

Application. This Pypes Catted X-pipe is designed as a direct bolt-on for the 1979 to 1995 5.0L V8 Mustangs with either aftermarket short tube headers or the stock manifolds and a dual catback exhaust installed.

      Very simple question, where does the cats fit? At the end of the down tubes before the x-pipes without cutting the down tubes or the down tubes need to be cut to allow for the cats?

      • The cats would install right after the down tubes and before the X-pipe yes. No need for any cutting or weldingto install the cats.

      I just got slp resonators and x pipe installed but I have factory cats , I ordered the pypes high flows , my shop said it was too much of hassle to install and they said I need direct fit. Will the pypes catted x pipe work ?

      • If you are looking to replace your current X pipe and your factory cats than this will be the kit for you. The Pypes Catted X-Pipe will include a bolt on X-pipe and two high flow Cats that can be mounted onto the X pipe with some slight trimming that should not be an issue.

          Pipe alignment

          The X pipe sounds great. The only problem I had was that the driver side did not match up to manifolds. My mustang was a manual and the pipe was hitting the clutch fork cover plate. I had to have the system cut, adjusted and welded. Over the car sounds like a beast now!

          Not a true fit

          This is not a true catted x-pipe! This is just an off-road x-pipe with a couple of cats. You will have to modify the down tubes (cut to fit) for your system to except the extra length of the cats.

          94 Gt exhaust

          Sounds great combined with my single chamber flow masters didn’t fit as nice as I liked with the stock headers but came into place nice with pypes shorty headers

          Not too bad....

          I installed BBK headers along with my x pipe hence the reason my review says an afternoon. To make your life a lot easier remove the driver side header from the head so you can maneuver the stock h pipe to get to the top exhaust nut. I found that to be the easiest way. Other than that it is pretty straight forward.

          Absolutely love em'!!!!

          I bought these along with the pypes catted x pipe and had my local shop install them. When I got my mustang back, it was louder and sounded a lot nicer than I expected. It's got an amazing rumble and growl type noise, which is a real head turner. I notice so many people turning around and listening as a drive by. I can feel a nice gain in horsepower too! I would definitely recommend these to anyone.

          Amazing sound!

          I got this installed on my 86 foxbody LX trying to make my V6 a little more beefy and louder. Took it to a local exhaust shop and it ended up taking the guy at least 3 an a half hours to install. He had to cut the ends off of the end where it hooks up to the manifolds and weld some new piping on it to make it fit. It was expected since this was meant for a V8. But boy oh boy when he lowered it down and i first cranked her filled me with so much joy i started giggling to myself! The exhaust note is amazing coming from this pipe. I have it running to an SLP Loudmouth catback system and it sure does make them scream for a V6! I definitely recommend this product to anyone wanting a loud growl from their stang. Can't imagine what it would be like on a V8...

          Plug and Play!!

          This is an amazing exhaust that went right in. When it showed up in smaller boxes I thought it would be hard work but it bolted right in. I used the Flowmaster American Thunder Catback Exhaust (87-93 GT) and Ford Racing Double Hump Adjustable Transmission Crossmember with it. I went home from work with an exhaust leak and plugged cats, tinkered in the garage for an afternoon, and went back the next day turning heads and getting compliments. This is an awesome upgrade at a fantastic price. I won't go anywhere else for parts.

          Great bang for the buck

          The sound quality is great, but for the cost of an extra hour's labor to get the Pypes to fit really well, it would have been just as or more cost effective to pay a little extra for a great sounding Flow Master or Magnaflow part, and have it bolt right in the first time without the cost of extra installation time.

          Street Legal X-Pipe

          Purchased this Street Legal X-Pipe as a replacement for my old worn out H-Pipe setup. It had a small hole at the weld around the X-Pipe connection, but the Exhaust shop repaired it easily. Was able to pass emissions in VA after a few attempts. My Stang has 291K miles on it. Note: This X-Pipe does not come with provisions for the airtube (94-95). The exhaust shop had to remove the inlet tube and attach it from my old H-Pipe.
