THESE HOSES MAY GO DOWN TO THE CATALYTIC CONVERTER(S) TO COOL THEM
SEE-UNS HOW YOU HAVE A 90s MODEL AND THE THING AIN'T BEEN HOOKED UP IN A WHILE EITHER YOU DON'T HAVE THE HAVE THE CATS, OR THEY HAVE NOT BEEN AFFECTED. I LIVE IN A REGION WHERE THESE THINGS AREN'T TESTED, NOR LOOKED FOR. ALMOST SOUNDS LIKE YOU ARE LIVING IN A SIMILAR REGION. IF YOU DON'T HAVE AN O2 SENSOR ON THE DOWNSTREAM SIDE OF THE CAT (I DOUBT THAT YOU DO). YOU MIGHT BE ABLE TO DO LIKE SOME OF THE NATIVES IN MY REGION DO.
