going to have a new lt1 dropped in soon and just wanted opinons on the best cold air intake setup to buy? best gains.. and also a loud deep roaring exhaust setup i have hooker longtubes right know but dont know what to put behide these headers opinons would be greatly appreciate.

 

I am fond of the Moroso cold air. I like borla exhaust as well, but it is not deep.

 

There's hardly any room for variation in design with CAI kits. Pick one.
