Description
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 Metallic 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.

Rugged construction. These Pypes Mini Catalytic Converters are build from polished 409 stainless and feature a durable Metallic substrate material making them perfect for force inducted 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 Metallic 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 Metallic Catalytic Converter Kit is specifically designed for use with power adders such as a Supercharger, Turbo-charger, or Nitrous equipped Mustang from 2011 to 2014.

Do you have to have a forced induction system with these or could you get them for just the sole purpose of having higher flow cats?

Ford Racing Cut and Clamp Would these fit the Ford Racing Cut and clamp Mid Pipe?

  • The FRPP cut and clamp x pipe will fit these. The FRPP cut and clamp reuses the factory cats. You could replace them with this if you so choose.

    Finally impressed with my exhaust

    I have been doing research for months trying to decide if I want to get high flow cats or not. Some ppl say that they are the same as your stock cats, I call bulls**t. I got the shop to install these, they did have to make a few custom changes to it but as long as there are no exhaust leaks I'm happy. I started my stang up from a cold start and instant smile on my face! I have the magnaflow tru x pipe, no resonators, and 10 series mufflers. I wanted a loud exhaust and it was loud before I put the cats on but not satisfied. After hearing my car now I am finally satisfied. As far as performance gains, I cannot tell because it was wet on the roads. No complaints the O2 sensors went in perfectly, no check engine light either. If you want your car louder I definitely recommend some high flow cats

    Great addition

    The sound quality is increasingly better, louder, and bolts up perfectly. Great product.

    Functional and compliant!

    Converters fit great while I made my own catted connection pipe between Borla long tube headers and Corsa Sport cat back exhaust. They came in polished and the O2 sensor fit perfectly inside of them. It was a good by if you want to be compliant.

    Does the job for inspection but exhaust note is still great.

    Before installation of these high-flow cats, my exhaust setup was stock headers - cat deletes - xpipe - deleted resonators - GT500 dual tip axle backs, and I loved the sound. But I couldn't get the O2 sensors to be "ready" to pass inspection. Even with the proper tune loaded. So I installed these and passed inspection no problem and the sound is still great, just a little bit quieter at low rpm. I should have installed these high flow cats to begin with.

    high performance catalytic converter

    The high performance catalytic converter awoken my mustang allowing it to breath better. I also gave it a better sound to it. A very deep note was accomplished after installed. It took like to hours to wield on. I was very satisfied, now I'm on to getting bbk headers added to my car.

    High Flow Cats with a Forced Induction setup

    Have to ship my car to Germany and must pass emissions, Was worried about the restriction from installing cats with my Procharger setup. Over 500 miles and feel no loss of power or lag, flows excellent! Can't beat the Price and As always AM shipped promptly! Will not buy from anywhere else!

    High quality Cats

    The quality of these are impressive. Small form to fit clean and fab into place. Much needed with my 3" heartthrob exhaust which is also the smart way to do this on a budget.
