Does anyone know or have experience with aftermarket cats when tracking ? Looking at downpipe options and would rather not go catless , but curious how some of the 200 cell offerings hold up?

Will they melt or blowout? Car will stay on 93 octane

Cheers

GESI cates used in the active autowerke downpipes are rated to 950 whp , they will easily handle the track stress

not all brands publish their cats rating, but give how many proven brands are out there and almost zero threads on failed cats, my assumption is that any of the proven brand will do just fine on the track

Thanks for that Mike. Could you pm the proven brands beside active when you have time? I see plenty of options but truly don’t know what’s what

Cheers

The cats Fabspeed use are also good, I would go with them or AA

I’d hope for the money they want with the quality car they wouldn’t blow out or melt on track

Fabspeed 200cpi use HJS cores - very robust. Miltek also use HJS cores. I’d avoid CPI >300 if wanting reliable DP that won’t melt under high loads/longer durations typical on track days

Fabspeed use HJS cats, Active use the GESI cats, probably the 2 best cats in the world

You have secondaries in the mid pipe too, unless you’ve changed your mid pipe

Oh interesting. I haven’t easily found the miltek ones for US market

Correct. I’ve done a non resonated single mid already. Cheers

I really was expecting a story about cats at a track with pictures… one of the most significant bummers of my lifetime.
