Headers, period.
Like me I am Getting Pacesetters with a TSP catted Y-pipe on a LM catback. I didn't know the deal on all of the o2 sims, and extensions without alot of research. Not knowing squat about it all doesnt help but tiny bit's of sometimes vague information is enough to get me highly confused and come running for help.
What i'm asking is maybe someone might be able to make a write-up of all those little things that are not well known. You don't have to make a whole new sticky. Even get the original writers of the other write-up's to include that information. It would help out alot I beleive. If you don't beleive so, tell us why.
Thanks for your time.
