Hey fellas , I follow a youtube channel called Autovlog, I'm sure some of you may be familiar with. The guy, Mike , has a 2015 F-150 5.0 that he's recently supercharged at VMP performance. He's already blown the engine due to a cat coming apart. It was still running stock headers/cats. I have a 2016 5.0 with gen 3 whipple and whipple calibration still running stock headers/ cats.

After reading all night on mustang and other forums, I'm paranoid to drive my truck any more for fear of falling to the same fate. I've been driving it a year and a half and roughly 15k miles this way and never really thought much of it til now. I don't beat on my truck regularly but I do live in AZ and it's hotter than hell half the year and only have crap 91 octane which just increases my paranoia. We have emissions testing so removing the cats isn't a totally viable option.

I've read about kooks green cats and have seen mixed reviews. Yes they seem to work , but a few supercharged Mustang guys had them start coming apart quickly too. I'm new to newer vehicles so I don't know what's possible tuning wise. I have a 93 twin turbo 300zx that has no emissions equipment (I used to register it at an old inlaws property in a different county, it's exempt now due to 25+ years old) but tuning on those old cars mainly required socketing the ecu and actually replacing the eprom chips, I don't think they do that anymore, haha.

I would like to do the headers and a cat-less exhaust and also have a setup for emissions time that can be swapped back and a tune. Is this fairly easy if I have the correct tuning equipment? I'm not crazy about making it a ton louder , raspy and wreaking of exhaust anytime I drive it, though.

Can some supercharged guys chime in with their setups , experience and opinions?

Short version is...sooner or later you’ll cook a converter with a blower. How long it takes depends on how you use the truck. I run mine very hard...regular pulls to 150 or more...so I don’t run any cats. All of the aftermarket cats have failed in high HP cars or trucks...I’ve not seen one option with no failures.
You're running the Whipple tune so you’re probably safe for a very long time...it’s a very conservative tune. Most failures come from people like me that are spinning the motors to 7500 rpm or higher.

How do damaged cats blow the engine?

clogged .. heat .. boom

From what I understand now the supercharger creates more heat, combined with more aggressive tuning can cause the element to come apart. Blocks the airflow and burns up pistons.

I sold a supercharged 2015 and the current owner had both cats go out but they triggered cel’s and were replaced before causing engine damage.
