We will be using the Evo R. As far as the electronics, I have no idea at all. As far as the loudness, the company is under new ownership.Will you guys be developing a new pipe and header or will you be using the Evo R system? Are they still doing the fuel controllers in house? I ask because I heard (rumors) stating they were stopping the electronics side of the business. I owned the Evo R at one time and it is super loud.
