ok.. so i remember someone saying that you can buy a bolt or something that will block off the hole on the Mac lt's... where would i find this item and how much. thanks

 

when i deleted my EGR i took my greasy header into the local home improvement stores plumbing department and asked if they had anything to cap it. haha i got some funny looks but they found a brass cap and it fit perfect they even put it on for me

 

What hole are you talking about?

 

right where the lt's would meet the h-pipe there is a whole that has a thread pattern where it looks like you could just screw something into it....

 

Thats the oxygen sensor hole. An oxygen sensor goes there.

 

I was about to say, Im pretty sure you I didn't have any extra holes on the headers that I had to go out and buy a plug to put something in it. Everything should already be there for you.
