I think you will probably gain some noticable power with another exhaust system. The TOR pipes are a compromise made to make the local customers happy without getting too many of them locked up for disturbing the magistrates' sleep, cracking windows and frightening small children.
By the way, be very careful to oil the unifilter according to the directions. Over oiling can restrict the air flow and cost you a few HP.
