Im getting duel exhaust on my v6 in the next few days, the dealer said I would have performance problems If he removed the cats from the system, I have heard that I wont, all I will get is a check engine light and it will not mess with ecc computer. I really dont want the cats on my exhaust system, but I also dont want to harm or get bad performance from the computer. Also thanks 5.0 guy for your reply.
