upgrade exhaust
After replacing the exhaust (going to Borla or Corsa) on my 94', I am wondering is there any additional modifications (tuning, computer work) to the engine that should be made to maximize performance? Thanks

If your 94 LT1 is stock .... your "stock dual exhaust" was non restrictive to begin with so the only thing you will change is the sound. My suggestion is to retain the stock cat back exhaust and spend your money on long tube headers. You'll get a lower deeper sound and no adjustment to the tune will be required until you change the cam.

I have a Corsa on my '95 and a Borla on my '96. Both without any computer tuning done and they both run fine.
They sound different than stock, but there are lots of ways to make the sound different such as headers, mufflers, eliminators, removing cats, etc.
If there is any performance gain, it is minimal. Like others have said, it will mostly be for a different sound or appearance.
Good luck.

I put a B&B 3" on my 96 LT1. It was maybe a bit lower tone. That's about it. Like others have said looks and a little tone wise. I still have the factory 96 LT1 exhaust sitting in the barn for that car. Not the best money ever spent on a car that's for sure.

If you haven't already done this, perform the easy mods of opening up your stock air intake/filter box, and the Throttle Body coolant bypass. Both are easy inexpensive mods even if they only added 1 HP.
