The cats that support 1200 hp are the Gesi GEN2 UHOX, but it has to be a 6" OD core. The ones we get from most of these header companies are only 4" OD, (think Kooks GREEN cats) which are only rated for up to 500 per cat. Part of the problem too, is that becasue of the long tube headers pushing the cats down underneath the car, you have ground clearance issues. I Wonder though if a 5" core would still fit, and will support 1,000 hp per cat.I ran them with my Ultimate Headers LTHs until I blew them out on the drag strip.

Aren’t the cats that can support 1200 hp super expensive (as in $3K-$5K)?
