I play proball and my buddy on my team has the doug thorley longtubes on his 09 6.2 silverado and he talked about it helping more with Power than even his Tuner. He wasn't lying. As far as installation goes. Just take your time and do it right. Take a day and do it right and it's not bad at all. Once you get the stock headers off putting the new ones on is not bad. Use PB blaster to loosen old headers. Much easier after

The headers arrived in good shape. Welds were solid. No dents or dings anywhere. I recommend reusing factory gaskets or get new gaskets from a dodge dealer because these gaskets do not have a heat shield for your valve covers/wiring.
