Miles F. ★★★★★

Installed these on my GT500 last weekend and the weight savings over stock is immediately noticeable in the car's response. The dyno-proven design gives me confidence the performance gains are real, not just noise.

Hazel ★★★★★

The sound is deep and aggressive at idle but really opens up when you hit the gas, just what I wanted for my GT. Installation was straightforward with basic tools, and the weight savings over the stock mufflers were noticeable.

George G. ★★★★★

Installed these on my '06 GT and the weight savings over the stock mufflers are immediately noticeable in the corners. The sound is aggressive but not obnoxious on the highway, exactly what I wanted for weekend track days.
