Ok, I am about to take the plunge and install my hooker 4" pipies using the glass packs or the JCLs. I am going to close the rear exhaust cutouts, so I am commited if I do it. Its a #s matching LT-1. I'd love to hear from other brothers who have these and how livable they are. I drive my LT-1 a lot. I'd hate to hate driving it because it too loud. Keep in mind that presently, I have a hooker header / Flo master combo installed and it sounds good.
