What is the difference between headers for the 93 lt1's and the later model ones? I do not have emissions testing to worry about so I could delete the air and egr if need be. If this were the case what do I need to do to accomplish this, and would I have to have a prom custom burned for this. I would like to put long tubes on it but the 93 is harder to find them for than later models. Any input would be appreciated. Thanks.

 

im pretty sure the only difference is the emmision hookups. if you dont have to worry about emmisions youshould be ok
