I currently own an 88 Iroc 350 tpi. Headers were put on it 2 years ago and the Air injection system was removed. I need to reinstall it to pass emissions!!! I have the air pump but there are no air tubes on my headers, it was suggested that i could run the air injection directly into the collector pipe. is this possible or will it not be effective?? I was told that doing so may force too much air into the exhaust. does anyone know what i can do short of buying new headers with air tubes???
