A few months ago we reviewed the Trailblazer SS in a Hoagies Garage Time Capsule story. The vehicle we reviewed was equipped with an SLP Powerflo Exhaust System that splits off into duals out back.
The system is not a cheap one and the changes in sound are amazingly different when compared to the OEM setup. Using our GoPro, we were able to capture what this system really sounds like out back. Driving the SUV, you really don't get an idea as to how this setup actually sounds. This video will clear up any confusion with what you are getting yourself into... Enjoy!
