Fuel, Daniel and I tested a ignition cut launch control and blew my cats away just after a few seconds.

The first part's good to know, the second part isn't. Assuming I make the mod only happen in park/neutral and I only rev the car a few times, is it safe to assume that everything will be fine?

I've been wondering the same thing. I'm pretty sure if you drive around for a while, your cats mights get damaged. But if you code it so it only pops on park/neutral, I don't think that should cause too much damage.

Yea im running the popcorn mod on stock cats, res and straight thru borla muffler. Audible gurgle, burps and pop but still quite subtle. Like a focus/fiesta st subtle. But ive noticed that the cats do get red hot lol. Time for headers i guess

Edit:
Went back to a stock tune. Seems like some of the sheet metal glows regardless. I guess I'm stickin with pops

Does someone of you experience missing pops above 4000rpm while driving?

I can share mine for the b25 but the throttle hang is almost unbearable.
