Hi Chris, I am running OBX headers. If you look around, you may be able to find a random speed shop trying to unload them for cheaper. I got my set for $450. I then sent them to Swaintech for their white lightning coating for about $350. It insulates them and helps keep the exhaust flow at a higher speed. The primary reason I got them coated was the bare stainless in the engine bay cooking everything didn?t sit well with me. I have seen pics on here of people running bare stainless headers but I wanted a little extra piece of mind.

Also, if you are not running EGR like the later ZR-1 models, there is an EGR tube on the passenger set that will need to be plugged or welded. I opted to cut it off, grind it smooth and had a local welder plug the hole. I will not say they are the greatest headers ever for an LT5, but I am pleased with them and they are weight reduction and dramatic relief on the restriction of the factory manifolds.
