Edmond, I work in down town.

 

Hey cstchevy , Have you ever compaired a NBS chevy 5.3L with regular duals an 2 flows compaired to a dual with a X pipe an 2 flows? I was just wondering, is it louder with the X pipe? I have been told that the X pipe makes it a little louder. An how did you connect the dual 2.5" pipes to your headers? Did you just weld the pipe staight to the headers or weld an new exhaust flang on to the 2.5" pipes an bolt it up to the headers? Thanks for all the info.
