Did 93 Sierras come wth true dual exhaust?
3 Answers
no and yes there not true duals meaning off the headers back to rear of the truck but they do have it where it comes off the headers into a y pipe which puts it in a 3 inch pipe then normally goes to ur cat and then to a muffler which then goes to duals from there
when i bought my truck i guess it t didnt have cats (found that out when i took it to an exhaust shop and they said no i put the exhaust on at home lol) but it had true duals and no o2 sensors are hooked up should i rig some in or just leave it?
