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.

High Flow. Are you looking to free up your restrictive stock exhaust, but are required by law to run Catalytic Converters? Then AmericanMuscle has the answer you need in the form of Pypes High Flow Ceramic Catalytic Converter Kit.

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.

Durable construction. These Pypes Mini Catalytic Converters are built from polished 409 stainless and feature a durable Ceramic substrate material making them perfect for naturally aspirated applications. They weigh in at 2.5 lbs each and only measure 11 inches in length.

Small Footprint. Installed, the Pypes catalytic converters have a very Small under-carriage footprint that only takes up a virtually invisible 7” in length making them perfect for custom applications.

Will pass most emissions tests. Pypes High Flow Ceramic Catalytic Converters will pass emissions testing procedures in most states. However, check your local and state ordinances for installation and usage regulations.

Application: The Pypes High Flow Ceramic Catalytic Converter Kit is designed for use with naturally aspirated Mustangs from 1986 to 2010. If you have a Mustang equipped with power adder check out the Pypes High Flow Metallic Catalytic Converter Kit.

  • The Pypes High Flow Ceramic Catalytic Converter Kit will make your exhaust louder if they will be replacing the stock catalytic converters.

I have a 2006 V6, has anyone had an issue using these with their 05-09 V6. I'm curious how it works with the single O2 sensor port on each converter. I could be remembering wrong, but aren't there 2 O2 sensor ports on the stock cats?

TheLegendJr

  • The stock catalytic converters should just have one oxygen sensor actually on them. The second sensor should be somewhere after the converter. With that being said, you should not have an issues installing the Pypes High Flow Ceramic Catalytic Converter Kit on your 2006 V6 Mustang.

  • The Pypes High Flow Ceramic Catalytic Converter Kit is a universal kit and will require some custom fabrication to make work depending on your application. We have this items installation rated at 4 hours and depending on the shop or mechanic that you go to and the price they charge per hour can vary.

    sucks the soul out of your car

    I got these cause I needed to pass emissions. I feel like even though there high flow there so small it restricts the exhaust quite a bit. I've noticed severe power loss since putting them on and a drop in mileage. It feels like I went from a v8 to a v6. If your doing this for emissions just make sure you have some flex pipe handy to swap them back out when your done.

    I have not installed these yet because im waiting for the O/R H-Pipe that i ordered with it to ship since it got put on backorder, so I will be updating this later. As for these cats, they arrived in 2 days and look great, very high quality and not a scratch or dent anywhere.

    High flow cats FTW!!

    I have installed these because my car was way to raspy and loud as i had installed the catless Pypes off road x pipe and the Pypes Bomb Cat Back. I did not expect any performence gain as i was looking into a better exhaust note but it did. I noticed the power gain as the throttle was more responsive, the engine flows better!! It also made the sound clear and less raspy, i get looks everywere i go as it is still just loud enough >:)

    This one fits!

    Had to put in some cats to be legal so i sacrificed HP. However it wasn't much so it was definitely worth it. I bought of some Slp high flow cats first but they didn't fit where they needed to because of my shorty H pipe and Long tube headers; these, however, did so i was quite happy with them!

    07 GT/CS, SLP Long Tubes, SLP X-Pipe, SLP Loud Mouths. Old cats went bad swapped them out with the Pypes cats, fit was great, they might have quieted the exhaust down while driving the DB sounded lower, but when you hit the go fast pedal the roar and snap was there!!

    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

    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.
