My first review disappeared for some reason and the second one wouldn't post. So I'll make this short, they flow so well i have a wandering idle but boost hits harder and the turbo spools 300rpms sooner. The headers didn't fit because they flanges are oversized and hit one of my engine mounts which I had to grind. The surface grind of the flanges I was not pleased with considering the price especially since one was marred. I'll be selling mine soon. I don't know the weight but it's heavy enough that the old knee trick will just make you lose some teeth and an eye.
