this will be about the most unscientific answer ever! I have had texas speed headers on a 08 ls3 auto and now have kooks on a 2010 auto, the kooks sound just a bit better to my ear. Both 1 7/8th, can't say why but just my opinion.

Just had Speed Engineering 1 7/8 headers and 3 inch x pipe, no cats installed with my stock npp exhaust, love the sound and performance with the tune. Got about 1300 bucks total includes install and tune and header purchase. I just couldn't justify spending 2000 bucks for headers and an x pipe then a tune for 500-700 on top of that.

No welding needed, used the provided clamps, no leaks. When I was reading the reviews some where concerned with leaks so they used high temp rtv sealant, I bought some but the shop I had install them said they didn't need to use it as everything fit great and the clamps worked fine, only issue was you need the 31 inch 02 sensor extensions instead of the 24 inch.
