bolt in mufflers will net you less hp. the cat back systems arent that bad, but there are good choices out there for 300 bucks. Hooker makes a nice catback for 300 bucks, and i'm sure there are a few others out there for around that.

DO NOT put flowmaster mufflers on an LS1. They sound like crap, and don't gain anything! Trust me, My car came with them, i replaced them with an slp LM1, and it sounds great, good gain! Flowmasters sound good on Slowstangs and LT1's, not LS1's

hahah my car sounds badass man!! i have no cats into the flowmaster, and it does not make much rasp at all unlike other mufflers outhere, but i am not sure bout the power, if it will loose power with the flow master then a cutout would fix that

Its all about preference.
Do what you want its your car.
I put one on and it sounded great and I got alot of compliments on it. I installed a cutout because I heard you could lose 20hp with a Flowmaster 80 series on our cars WHICH was wrong on my car anyways.
I always drive now with the cutout open but honestly there were no seat of the pants feeling of a difference when I installed the cutout.
Oh and right now the **** is loud after I installed Mac headers and an SLP ORY and I love it. I cant wait to cam this bastard.

40 series is a direct flow. 1 in 1 out on opposite ends of the muffler this is a normal muffler and you have to do some fab work if you want to use 1 muffler but have two exit out the back.

80 series is a crossflow. 1 inlet 2 outlet with one side having an inlet and an outlet and the other side only has an outlet most F- Body cat backs use this style the Flowmaster just isn't very efficient.
