OK guys need your help,Looking at putting on headers,but which ones,and Ceramic coated,or stainless steel?,and By putting headers on will gain or lose mpg?Last I want to get the best bang for my $$$.

 

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.

 

+1 for pacesetters

 

okay but I cannot find the OBX headers and y-pipe for my 04 5.3 rcsb. I can only find them for 6.0 trucks

 

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 heard they obx had fitting issues? but i really like it made out of stainless steel.
tell me how it fits.

 

The guy who sells them I believe is "Sparktec motorsports"

If we have enough people we should try and get a group buy going.

 

grp buy will be nice how many would we need to get grp buy 10-15?
and how much Discount are they going to give ?
if u going to organize grp buy let me know.

 

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.
