Camaro LS1 header installation. NEED HELP
 

i just recently took off my stock 99 camaro z28 ls1 headers and am about to install my new long tubes. My problem is my new headers do not have points to connect all the different hoses and plugs that were connected to the stock headers. which ones can i block off or eliminate? and what do they do?

i did some research and figured it out. incase anyone comes across the same problem as me. the stock headers in a 99 camaro LS1 and i suppose years around this have three pipes going into them. two are called secondary AIR, these i believe are used to heat up cats after starting your car for emissions purposes. the other is the EGR. i dont kno much about this pipe. all three can be eliminated, and then tuned so your SES light does not show. (like i have done) performance is not affected in any way. it mostly just cleans up the engine bay.
