800whp Catalytic converters?

Skyman · 11-14-2020, 11:04 AM

Hi guys,

Finally got my M6 running well making 780/825 on pump plus meth.
I am running catless and for a convertible I want to run some cats, plus it’s a CA car that will see smog soon.

My factory cats plugged and failed once. I’ve welded some in the mid pipes on a F10 M5 in the past and the results were so so.

Anyone know of some cats that can handle this level of power and remove the exhaust stink ?

Thanks!

May I ask what mods.

I would say maybe those high flow cats? Basically would be the same as the catted dps that are sold for these cars..

No issues at all. Just I would ask what your goals are and what fuel and other mods you plan to run...
