I have a 1992 Ranger XLT 4.0 and my truck brutally failed an emissions test here in Ontario, Canada. I am going to replace the catalytic coverter but i cannot tell if i have 1 or two. They look exactly the same, but are one after another on the exhaust pipe. So im not sure if one is a cat, and the other is the resonator. Any help is greatly appreciated. I want to get my truck on the road ASAP!
