I was looking to buy an aftermarket air lid. The only mods my car has now is a Corsa cat-back and a cut-out. What size lid would you recommend for my car (2001 Camaro SS)? Also which is the best performance wise? Thank you all!

A lid is a lid, period. Pick the one with the best fitment (Whisper and SLP seem to have the best, though the SLP lid is known to rub with SS hoods). You'll want the stock size (75mm). Anything bigger isn't necessary with the stock size induction.
