Sounds good, I'm planning on doing just that.
Side question; does anyone know if part number 22 includes both the black plastic underbody panel AND the 2 metal heatshields that are attached on the sides? My driver side heatshield that is attached to the underbody panel is missing a chunk, looking to purchase a replacement but not sure if part number 22 in this link is JUST the black piece or includes the 2 side heatshields.
