Who makes them for our cars or what are people using for cats other then stock??
Not sure who makes The factory cats but according to Van at Revan racing, they flow really well. Deleting them altogether with an offload pipe only gains 6-10 HP as I understand it. Since cats are costly, not sure it would make sense to replace them...just my opinion though.

Thanks but I have long tube headers and am looking for a set. :beer:
Yep. At just under 720 rwhp I blew the cats out of my old SW midpipe in my '03 Cobra. The whole thing blew out on both sides and looked like inverted cones sticking out of the back of the pipes. That was the end of that.Don't waste your $. If you drive the car hard they won't last, they all suck.
