Easy swap at the track. Every car enthusiast knows that catalytic converters suck the lifeblood - horsepower - out of your engine. If you're running a Pypes modular x-pipe style configuration for track / racing purposes, these cats give you an easy way to be street legal when you leave the track.

Hey I’m Justin with AmericanMuscle.com, and I’m going to be reviewing Pypes high flow cat system for all 1986-2010 Mustangs. These cats are going to be a great compromise for those of you who are required by law to run some sort of catalytic converter system yet still allow you to ditch those ultra restrictive factory cats for something that’s going to flow a lot better, making for more power and sound versus your stock cats. These are going to also be great for someone who might currently be running an offroad X or H pipe, and just wants to tone down that rasp a little bit. This system from Pypes features durable 409 polished stainless steel construction and a very small footprint. This is going to be great for those of you going with a custom exhaust setup, or those of you who might be lowered an inch or two, and won’t have to worry about scraping these over speed bumps. A very important thing to point out with this particular system is that it features a ceramic substrate material on the inside. This system should only be used if you’re naturally aspirated, if you’re forced induction, then you’ll definitely want to check out Pypes’ other system, which features a metallic substrate on the inside, which is far more suitable to handle those higher exhaust gas temperatures. Getting the cats installed should only take you about 2 hours using these two supplied clamps. However, depending on your exhaust setup, you might need to go to your local parts store, and just pick up a couple more clamps. So if you’d like to go to an off road X or H pipe but your local laws just won’t allow for it, or you just want to get rid of some of that excessive rasp with your aftermarket exhaust, without hurting your power, you’ll definitely want to check out a set of these affordable high flow cats from Pypes Performance.

  • Yes these will work with any exhaust setup. You may need additional pipe up-sizers and down-sizers.

  • Depending on if your state has a vehicle inspection code you may not need any but if you live in say Louisiana you will need only 2 to pass inspection in any state

Fitment Are these a direct swap for a factory H-pipe on a 2010 GT?

0gmstucke

  • If you mean are they a direct swap to cut out the factory cats and put these in, then yes they will fit on the stock H pipe.

    Absolutely no restriction

    I previously purchases JBA shorty headers, Pypes x pipe and Magnaflow Magnapacks for my 2007 4.0 mustang. I thought that with that setup my car had an awesome deep loud tone to it and sounded great when accelerating. I just had these cats put on and the difference with just simple cats is ridiculous! I thought with the setup I had before I had a sick sounding car, but once I put these on and accelerated and hell when I even turned the car on I was in complete shock I highly recommend these, its a cheap and easy way to get the best air flow out of every mustang

    Amazing Product

    Have to say these are the best aftermarket Cats on the market, better than the magnaflows i had on my previous car, my installer had to cut the cat pipe down and fab up new piping but def worth it, on my 04 i was even able to use the O2 bung on the cat, A MUST if you wanna stay legal and have extra power and great deep sound with flowmasters!

    Pypes Cats

    Looked for some "high-flow" cats when my stock ones died. Put these on my V6. I wasn't expecting a difference in the sound department, but these made my pre-installed Ford Racing Dual exhaust sound much deeper. I've also noticed a bit of power gain. Can't wait to Dyno to see how much. I recommend this product and I approve this message.

    Great Product

    I have had my 2003, 3.8L for about a year now. ive done a few things to it, new transmission, clutch, and an 8.8 rear conversion. Had a nice dual exhaust setup on mine. i had stock cats, and just today my cats came in. Oh My Goodness, the big difference in sound, power, and surprize was amazing. ive actually had peope look at my car and ask me if it was a GT. Very good product, very nice employees on the phone. Very Nice setup. Thanks for everything guys!!!

    Great Bang for your buck

    These cats provided a nice amount of horsepower for the money paid and also improved miles per gallon. i added them to a bassani x-pipe with flowmaster mufflers in which one of the previous cats had hollowed itself out giving a messed up reading to the O2 sensor. The sound didn't change too much, maybe a little deeper than before. The only drawback is only clamps for the front came with the kit. I had to use an adapter for the rear portion and it had to be welded. Still a great product though.
