The Right Exhaust
You won't regret it down the road. You really need to hear any exhaust in person to get an idea of which system you like.
With that said, GMMG is so much more aggressive sounding on a stock LS1 than other systems, likewise on heavily modified LS1's with LT's the sound just gets better. Plus the quality is excellent unllike the rash of bad Corsa mufflers that was going around with internal parts rateling around inside.
However - I love the way it sounds at WOT!
