Excellent
By Joe Polito
You get what you pay for. Gibson is a quality product, you wont be disappointed. Bolt on easy, gaskets are a good high quality material, just use a gasket sealant, i'd recommend the heat red tube, torque to 35ft lbs and you're set.Very happy

By Adam m
These stainless headers are a great upgrade from the stock manifold I installed them on my 03 avalanche 1500 5.3l they were bat that difficult to install. The only challenge came when both rear manifold bolts on each side were already snapped off in the head when I got there but my neighbor is a welder and was able to weld a Alan head bolt on the broken stud and back them out . But after those came out install wasn't overly difficult

By deepsea
I found these headers for my 08 Chevy Silverado CA truck from another web site. I do not live near the ocean so I purchased the Chrome ones versus the Stainless steel Headers. I have a mechanic background and found it relatively easy to install. However, one of the stock collector bolt had to be cut off due to heat fatigue. The headers fit as described in the instructions with no modifications. I recommend following the installation instructions word for word and there will be no problems other than the unforeseen one mentioned above. The headers look great, the exhaust sound barley increased, but the engine torque increased. I purchased the headers mostly to give me more horse power to pull my toy hauler trailer. The headers are in conjunction with a GM cold air intake, Magna flow muffler, and a computer chip.
