I had a full 3 inch system installed onto my B23ET in a 245 and asked that it be quiet. What I ended up with was two big straight through mufflers with the one in the rear being quite big. They also put a turn down tip which reduces the noise in the cabin by a fair bit. It has a quiet rumble on idle and when on the power the sound of the turbo is much louder than the exhaust. No drone and am happy with it. If I remember the guys at the shop said that putting the big muffler on the back made the biggest difference when they were trying out a few different things.
