i need some info. im installing slp long tube headers on my 1999 trans am, and i got one problem. the stock manifold on the passenger side has two valves on it, but the headers only have one. im stuck on that one part and its driving me nuts, also i need to programmer, anyone got any suggestions?

If it only has one then they are the wrong ones but you can take the egr off and get a LS1 tone all you well need is a 1 3/8 plug for the intake

rubber freeze plug that is. or just cut the port off the stock manifold, and weld it to the header...

ok i think ill block it off, what about the other two flanges on the headers? should i block them off as well? also where would i get a 1 3/8 freeze plug???

the plug you can get at AZ or O'rielly's... the other flanges are for the AIR system.. Delete if you want, you can turn off the codes it will throw for EGR, and AIR with a tune.
