Step 2: The resonator box was removed. The oval whole in the chassis leading to the resonator was expanded to a 3.5" diameter circle with a rotary tool with cutoff disk attachment. Cutting from the buttom with the car elevated is the easiest way to do this. (This whole should be a little larger than 3.5" to accomodate the elbow.) The battery tray must also be trimmed in order to fit the elbow. The whole was then cleaned, painted, and coated with an acrylic sealant to prevent corrosion.
