WRONG! my '93 C1500 has a C3500 exhaust system from the "converter" forward. all factory GM stuff too, 3" y-pipe and my "converter" is a straight piece of 3" tubing. these are genuine GM parts that i ordered through GMSPO when i was working at the dealership. like Chris said before, it all has to do with GVWR.
