these are '73 RS MFI versions which should also be on your car

Left side w/ heat stove for MFI


Right side


SSI used to make clones of the oe headers for these cars, you don't want any exhaust leaks which were common in the old days before stainless was used, CO poisoning is insidious. You always want the covers to rot out before the header tubes other wise CO can get in to the cabin. The first versions were all mild steel, then they went to SS tubes w/ mild steel covers, I'm not sure if the factory ever went to all SS on these as they switched to the totally different smog exhaust in '75

SSI clones of the oe heat exchanger/header system, these are for later cis cars, no heat stove


remove the heat exchange cocver and you find the header tubes
