Main power gains will come from removing the cats, just changing backbox and filter IMO won't give you much more power, maybe 10bhp?

With a classic (presume newage much the same) you can get up to 30bhp changing full-system and filter.

A lot of people just change panel filter, myself included, green or STi filters are popular. As for zorst prodrive or scoobysport are not too noisy according to others. I have a ninja - pretty noisy but not OTT
