yo RR, What engine is in the Bronco? and I ASSume it is a 93; correct?
If you go with a stock exhaust; consider WALKER exact replacement exh parts, I use Walker, who was and prob still is Ford's OE supplier (esp for our Broncos)
Use pn's and gOOgle for sources & prices; then try locally and have them beat or match prices.
Use aluminized or SS
if not a 93 5.0 Bronco then find the cat converter in Walker's catalog @
