The air tube on my 92 GT has popped off of both cats and i wanted to get a new header back exhaust without cats. I was thinking of different things i can do like disconnecting the air pump or removing it all together, but if i can just put a cap on the air tube that'd be easy. I have heard different things from different people about their cars (88 crown vic, 91 jeep) not running as well as it had before the removal of the cats and pump. So what would be my best bet for going about and putting on a new exhaust without the catalytic converts (for sound purposes) without loosing power or having problems?
