Hello everyone. New to this forum, not forums in general. So I recently traded a harbor freight 3/8 socket wrench with a set of shallow/deep standard sockets for a 98 cherokee 2 door 5spd with a 2.5l. Currently rebuilding engine. Previous owner was a younger kid. Had exhaust all chopped. Complete straight pipe from manifold to rear bumper. Has no cats or o2 sensors. I'm in search of a complete exhaust diagram with locations of o2 sensors, cat, muffler etc. Could not find one in forums. Any help would be greatly appreciated. Tips and suggestions are always welcome. Thanks everyone.
