245 Stock + 10 for mufflers + 5 for the rest = 260 Crank
Assuming a stiff 20% drivetrain loss, you're at ~208rwhp / 285rwtq
Just armchair dyno numbers...not a ton of worthwhile stuff you can buy for under 350, the site you want to read is http://temp.corvetteforum.net/c4/vader86

I'm planning on doing the same thing, if I can determine that removing my precats are legal here. Exhaust is a good place to improve the 85-91's...don't know about the chip. Haven't heard much if any positive info on them.

Good place to start. L-98 is serverly chocked by the exaust. Why not go with true dual, muffler eliminators and high flow cat. I sold my mufflers, air foil, and K&N. They wernt enough to do anything. I am running basicalyl straight manifolds at the moment because I am trying to get new pipe. Invest in headers later down the road when you can afford them.

At most 20 over stock.
Chip is a paperweight. Catless front Y helps, but its up to you whether you think its worth it to get 5-10hp from that for its expense.
