best cat back
I have a 98SS with the SLP 2-to-4 exhaust. What cat-back system should I install to get the most horsepower with the least additional noise (the SLP sounds fine--I want more power only)?

Are you saying you have the optional SLP dual/dual? If so, that is one of the highest flowing catbacks and you probably won't gain much, if any horsepower with a new one.
