Silverado Sierra Truck 1 7/8" Longtube Headers 2014+ (4.8L, 5.3L, 6.2L Engines)

Originally ordered JBA 6853S stainless steel long tube headers. Arrived with a damaged box. Quality and craftsmanship were well below average, in my opinion POOR. They were only tack welded on the outer flange and terribly welded on the inside. None of the ports were symmetric and the collectors were full of metal shavings. They were not polished and appeared used. So I gladly returned them. Found the Speed Engineering on a YouTube video and looked them up. Liked them so much I ordered them for my application. Received them a week early. Opened them up and they were exactly what I was expecting from the video and photos. Polished stainless steel, tig welded inside/out on the flanges, pure quality. Ordered 2 sets of 304 polished stainless steel v-band clamps and weld on flanges. When these are mated together they will be nicer than stainless works, kooks, etc. which all costs well over a grand Poly. I will have spent $355.00 for my set up with better quality than these over inflated companies. Can't wait to install them with the new hi-flow converters I bought.
