alright i just bout this 1990 ranger 4x4. plan on making it a mud/trail rig and DD. gotta lift for it on the way and new intake. but anyway, truck has no exhaust, use to be my friends and he cut it off at the manifold, so no cat or anything, so obviously no back pressure=no power. can i throw on some duals with a cherry bomb on them for enough back pressure to get some power back or do i need to replace O2 sensors and Cat? i would rather not do that, expensive even doing it myself.
