Stock...we have manifolds, not headers.

It's only a PITA if you aren't prepared. Ratchet strap the engine forward...remove misc. bullsh1t brackets...its a cake walk. Delete the EGR and Converter in the process.

Speed Daddy headers also seal just fine as long as you use plenty of high temp RTV...the people that have leak issues just put a dab of it on...don't be afraid to use the sh1t.
