The installation process would have been much easier, had all of the necessary parts been shipped. Having to purchase parts from a local hardware store that were missing from the package put a damper on the entire project. Having said that, I can definitely notice a difference in performance. Engine RPMs are lower, gas mileage has seemed to improve and the motor has a subtle, but notably deeper sound.

It was very easy to install and took about 10 minutes. Made out of high grade aluminum. Got a good boost of hp but the gas mileage didn't change much. All n all good quality and I would recommend for other trailblazer owners.
