Steven L from Aurora, IL said, "Received the package earlier than expected. Installation took the 90 minutes that was expected. Problems w/ the fire shield (had to trim back some of the tin flashing) and hose clamps (reused a stock clamp, and the large clamp to hold the filter was missing, so I used 2 smaller ones together). The immediate noticable change was in the new growl coming from under the hood! Performance-wise nothing to noticable; finally averaging 20mpg, and pickup is a little quicker. Great buy if you like the tuner sound of an engine."
