Iím probably the last Solstice/Sky owner to install an aftermarket exhaust system. The decision to install the Solo system was motivated by:
1. Purchasing a 500 Abarth as a daily driver two years ago; the factory exhaust system in the Solstice is quite a letdown after driving the Abarth.
2. After 7 years of ownership, it was a good time to spice things up, on an otherwise completely factory car.
Before/after audio clips:
Itís a good change. Iíd go so far as to say the Solo Mach Shorty system makes the Solstice sound a bit exotic. I think my favorite part is the way the exhaust burbles after letting off the gas. As for performance, I donít feel any difference, as compared to the stock system.
The only conócontrary to what Solo states on the their webpage--is some droning: parts of the car vibrate that have never vibrated before, including somewhere in the boomerang under certain engine loads. However, itís by no means unbearable, and the droning doesnít have a material effect on normal cruising.
