Long Tube headers 11-14 GT 5.0
I have ordered from Stainless Works before for my 2021 RAM 1500 "long Tube Headers and X pipe” and they fit perfectly and were fabricated extremely well...which is why I purchased Long Tube Headers and X Pipe for my 2013 GT 5.0 and they also came fabricated extremely well...I only wish they were associated with Jet-Hot Coatings to limit the turn around time for those of us who need to keep engine bay heat down...but over all the quality and customer support along with price are unbeatable I would highly recommend if you are looking to modify your build with headers and X pipe this is the place to go!!!
