I am putting together a single cab 2006 z71 into an awd ss clone. I have a low mile LS6 motor and a mp112 magnacharger about to go in. I am considering the arh 1 7/8" catted longubes but am wondering if that is too much primary for the truck. I feel like with the boost ill be fine but justwanted to checked around and see what everyone thinks. Im gonna run a 3.0 or 3.1 pulley so I wont be high into boost. Let me know what you guys think...

My 5.3 was a freaking animal with a 2.8 on the MP112, and 1 7/8" primary headers. I didn't lose ANYTHING down low, and gained a bunch up top. I'd recommend the 1 7/8" headers, you won't be disappointed.
