i took my car to the guy that did my catback and he said he could remove the cats then put either 2 or 2.25 press bent pipes to my catback..cost 250$, i asked him why he couldnt just cut off the cats and weld in a 2 inch pipe and he gave me some reason....anyways what do you guys think?

thanks
ryan

make sure your AFM is properly connected and check all the ground points for the timing and trans computers. you may have a bad cat but only because it has been damaged from an underlying mixture problem

sorry for the attempt hijack, but i was wondering, ps i would remove the cats immediately, run a straight pipe through them, or the worse option to gut it out, either way get them off severe engine damage is going to occur if u do not.
