Please note this is a custom fit part. This down pipe will likely require for you to modify and push back the firewall for clearance. We recommend to use a Porta Power hydraulic tool with the expanding wedge or jaw attachment along with a couple short 2x4 wood blocks as it by far the easiest and least invasive way to make room.
