The GTS has more resonance than an RT/10. The Corsa systems help this a lot.

I'm very pleased with the Corsa 3". It sounds great at idle and when you get on it, but at highway cruising speeds in 6th gear (and probably 5th, although with 3.55's I'm running a little higher RPM than with the stock 3.07's) there's no drone.
Other exhaust systems may add more power and/or volume. However, since I often take my GTS on trips of 4-6 hours in duration, I didn't want to listen to a performance exhaust droning away continuously.
