Coated, hands down. MPG +/- depending on your right foot habbits. Pacesetters are the best bang for the buck. You will need to retune for them to see any gains.

From my searches, Pacesetter's are very inferior to OBX headers. There's no comparison between a so-so ceramic coating (pacesetters) and stainless steel (OBX). OBX's are cheaper too ($485) AND have flanges compared to pacesetter's which are prone to leaking. To me, there's really no comparison. I'm going with OBX. No fitment issues on 2wd.

ebay type in "OBX headers 5.3L"

The listing should be $499. I messaged the seller and he said he would accept $485 shipped via Money Order.

I haven't organized anything. HirdleJ thought it might be a good idea if we got enough interest. I want to buy a pair. I will email the guy again and see what he says.
