Installation Tip: Because this is a raw steel pipe with a clear coat, avoid touching the header with bare hands during the first heat cycle to prevent oil spots from etching into the finish. Pro Tip: To truly unlock this pipe, ensure you are running Lighter Roller Weights to keep the engine in the V8's higher powerband!
