Exhaust drone

I've been searching for a while and have yet to come up with a straight answer. Does anyone know which exhaust system or set up has the least or no drone. Im in the market for an exhaust but i don't want anything to loud or with little or no drone.

caddyliciouz...you must not be feeling well today, you didnt tell him to put 22s on it...and seriously, why would he put flow master super 40s, straight piped on his CTS if he doesnt want that much noise?

i have been doing the same research and found magnflow for a v sounds good very little inside noise too.

I've been hearing things about the Borla Exhaust. Im still looking into. The thing is i want some sound, but not to much and no DRONE.

Corsa advertises that their exhaust doesn't drone. I will find out on my own in a week when the exhaust I bought comes in and I install the exhaust on my STS-V.
I had magnaflows on my V6 Taurus SHO. They droned and they were also raspy. I added two bullet style Magnaflows to cut out the rasp, but still got some drone.

So Bob,

Clue us in; how did it turn out?

Here is a clip of my 1991 SHO with stage 1 cams, custom headers, custom y-pipe, custom mandrel bent 2.5" cat back, two 2.5" bullet style Magnaflows in line, split in the rear with Magnaflows on each side. The exhaust is still pretty loud when I rev the engine. The mic was 10 ft behind the car. The engine was already fully warmed up when I started the car. I think it really hard to get a good sound from a V-6. I don't remember how high I reved the engine in the clip.

This clip I slowly raised the rpm to about 4000 then floored it to about 7500rpm

The Corsa for the STS-V is due to arrive Monday. Hopefully I will have it installed Tuesday. I am hoping that the exhaust will about as quiet inside the car and sound more aggressive outside the car.

One more factor on how loud your exhaust can be is determined by the diameter of the exhaust pipe. When I initially installed Magnaflows I just replaced the stock mufflers with the Magnaflows. I thought this set up ended up sounding the best. The exhaust became much more louder when I installed the 2.5" cat back leaving the Magnaflows on. Then I added the two bullet style mufflers to reduce the raspyness and lower the volume. Before I added the two mufflers, I was setting off car alarms in parking building and on the street.

I think im going to go with this set up:
2 of these http://www.summitracing.com/parts/BOR-40981/
and 2 of these http://www.summitracing.com/parts/HSH-12412400/
Im all so adding 2 1/4 inch stainless steel piping to replace the stock piping.
if it doesn't have the sound i want then i will add an X pipe. Let me know what you guys think. Like i said i want some sound but not much after all it is a lux sport car and not a honda civic.
