+2 on that one. I still dont understand why they had to put this on the Fbods when they didnt put it on the Ybods. Oh well.

No you have to remove them. Search for it. there is alot written up on them. i wouldnt do it until you are in the market to buy a new set up headers though. and then when you want a new intake manifold your all set, no egr.

EGR - laymens terms....its that funky hose thingy that goes in front of the intake manifold. It measures "stuff"

AIR - is basically an emissions thing. The two hoses that run up the (inside the engine bay) and breaks all the time

ok so if i ever install an ls6 manifold, i'll have to delete the egr anyway?

Yes. Here check this link out. Its a sticky. Read up on this and it will clear things up alot better for you I think. THere are some pics in there also so it will diagram where we are talking about. AIR and EGR does nothing to performance in my opinion. EGR maybe a little, but nothing significantly. Here is the link.
