"Best sounding exhaust" is a moving target. My exhaust "journey" 
resulted in an exhaust note produced by a custom-grind cam and supercharged LS3, Kooks LT headers with green cats/x-pipe, and a Corsa Indy Pro axle back. I like it as there is no drone although the headers are a lot louder than the stock manifolds. It has a strong idle and roars when I put my foot into it making it a lot of fun when driving around town.

No matter how you cook this chicken, you're gonna make more power. The gains only go up with a tune, and we can all agree on that

40hp, 50hp, different dyno's, different techs, etc. With just a tune and bolt-ons, I ran 12.80s@110mph in the 1/4 mile in a stock internals 2000 A4 vert with 3.15 gears. This was THRU STOCK EXHAUST MANIFOLDS! I'm in the camp that believes a tune will net more power than LT's ON A STOCK INTERNALS LS1/LS6....
