How did AIR injection connect to dual-cat systems. Interested in retro fitting.
Hi guys, can anyone tell me or diagram how the air injection lines from the smog pump connected to dual cat systems? I am going to run a dual exhaust with dual cats, and I am going to keep the air injection system (not because I have to, the car is exempt, but I want the AIR system active and functional)
Did the dual cat cars get a different AIR selector valve assy. with two outputs, one for each cat, or did it tee the AIR output to the catalyst after the selector valve?
thanks

Pretty much the same as a single cat but the AIR pipe to the converter splits and goes to both. I have a dual cat Y-Pipe I could send you a picture if it would help.
