Are you looking for just a CBE or a HFC/TP combo as well? I can tell you keeping the stock cats will remove any drone.
Fast Intentions gives you a multitude of options to look through:
Long Tube Headers
HFC's/(R)TP's
12" Resonators
18" Resonators
CF or SS Cans
All of which can be mixed and matched to produce exactly the performance/sound you want. With no drone.

This is absolutely incorrect. I just got a FI catback with 18" resonator installed early this week and it drones like CRAZY between 2000-2900 RPM or so under load. Most prominent when you leave the car in auto (D) which seeks the tallest gear always, and then either climb a small incline or generally just speed up slightly (accelerator pedal down about 1/4 to 1/2) without pushing hard enough to force a downshift to a lower gear.
This problem is easily solved by using a Helmholtz resonator attached 90 degrees off of each pipe, but for whatever reason FI didn't take this issue seriously and as a result their exhausts have this problem. I am in fact going to take a loss by having to pay labor twice to have the FI exhaust removed and the original up back on, this drone is so annoying. Telling people they have no drone is causing people to waste money only to find out the truth.
