best bolt ons

I have a 2000 ls1 from a firebird in a 1991 firebird looking to do some bolt ons for better performance. The engine has no cats no egr no air and a specter air intake other than that its stock. So what would you guys suggest the car is daily driven the performance is good but it can always be better.

it has the t56 and 3.42 gears. I was thinking of the ls6 intake what kind of gains should I expect from that or would I be better off with an aftermarket manifold?

The single bolt on that gains the most power is a full exhaust and the required tune. Headers, high flow cats, high flow cat-back system.

All the other bolt-ons might just add just a few HP each, depending on the engine running condition and tune.
