I know there is another thread about this but i cant find it. I have a 99 rcsb 5.3 Z71, i want to put a set of longtubes in. I found this set of ebay for 255 here is the link, has anyone used these before and what does it take to do this project, can it be done in a weekend with basic hang tools, is it a direct plug and play kind of deal, and will the truck throw some major codes without a tune. thanks for the help any advice is most appreciated.
