Stop Droning On
If you are looking for an aggressive exhaust sound and more power, but are concerned that you’ll end up with exhaust drone, you should check out Billy Boat Performance Exhaust PRT and Fusion Systems.
The sound of the PRT is more aggressive than stock - but it doesn't drone. It is a bit louder than stock inside the car - the system was designed for those who want a better sound, but not too loud. I would describe it as being more on the mellow than loud side inside the car. More info: http://www.bbexhaust.com/car/corvette/c5/
We also have our Fusion system, which is much like the NPP, using butterfly valves to direct exhaust flow through loud or quiet passages. It can be put in place of the factory NPP mufflers, and is actuated by the signal from the factory NPP. It can also be controlled by an interior mounted switch. We also offer a retrofit kit that to install the system on non-NPP equipped vehicles. The valves are controlled by an interior mounted switch with this set up. On the loud side it sounds very aggressive - like our Bullet exhaust. On the quiet side the sound is more tame and doesn't drone. Basically, the same sound and no drone as the PRT. Compared to stock it makes an additional 10-12 hp on the quiet side, and 18-22 on the loud side. More info: http://www.bbexhaust.com/car/corvette/c5fusion/
