LS6 Intake or LT's?
The LTs and ORY will require a tune(get rid of EGR and rear 02s) but will knock some weight off and offer good power. If you don't want to tune LS6 intake and ported TB is a nice mod and can be bought used on here for around $400. Expect about 2 tenths and over 1MPH improvement if you race the car at the track

I've owned a couple pre 01 LS1 f-body's and I've modded them both ways so I'll share my experiance:
The more power you make, the more you'll pick up going from an LS1 intake to an LS6.
Say you have a bone stock motor making about 280rwhp. Going from an LS1 to LS6 intake won't wake it up much at all. You're making stock power so the intake isn't a really a massive restriction at this point. It'll breath better but it's not going to FEEL much faster. You might feel a little more tug on the top end but that's about it.
Now lets say you do the exhaust first (big bottle neck) and you're making about 320rwhp. Now your car needs more air coming in to compliment the free flowing exhaust. At this point your intake is holding you back a lot more than it was before. You throw an LS6 intake on it now and it is going to make a much more noticable difference. Especially in the mid and upper RPM range.
For me I like really being able to feel every mod that I do, and when I did the LS6 intake first I didn't feel ****. BUT when I did my full exhaust on my LS6 intake car it felt like it picked up a lot more than when I put full exhaust on my LS1 intaked car.
So long story short, if you like feeling the difference an LS6 intake makes do it after exhaust. And put a ported TB on it at the same time.
