You have emissions in your State? if not delete them. If you have to keep them try to find you some CATS from someone who deleted them so you get a good OEM product.
I'm in the ATL Metro area, so yes I still need them. I honestly was a bit leery of getting them second hand because my experience with all F-L-M is that the cats go out quickly along with that damned air suspension.
If it’s legal in your state, you might as well get an aftermarket catted x pipe and enjoy a power gain going from 2.25” to 2.5” pipes. I’ve had a magnaflow catted x since 2003 and still pass smog without issue.
Engine runs fine. The only fault is slow to heat. Its been so long I don't know which ones are throwing the code.
