If you think about it...there really is no way to have a 700+ hp truck and drive it every day and not pay an arm and a leg for gas...everyday.
As for the headers...this is kinda an odd question but...i know they will fit on my 5.3L but if I buy them for the 5.3 they will direct swap over to the LS1 right?? As for the ceramic vs. painted...how big if any is the difference in power and sound?
