Has anyone Added the stock valve to mpe exhaust? I wouldn't mind the option to quiet it down mainly on startup.

the valve does the exact opposite of what ur thinking during start up. it opens the valve for the first 30sec during the initial cold start THEN closes, so no adding the valve back in wont achieve what u want.
