Ok well I have been trying to figure some tech information on the GT forums for a friend and I stumbled upon a forum that said that on the GT and Mach1 and what not you could hollow the cats nearest to the headers and not trip the cats since those are the warm-up cats. Is this also true for our cars?
 
too loud. lol:D but if i can do this without tripping the check engine light then i will go ahead and do it, does anyone else know if this would work the same for the 6 as the 8. cuz i dont want to trip the CEL light.
