This is my system at install, no butterfly valve, the short bypass pipe is added and the bung is removed from the pipe to enable a straight through setup all the time.

Same thing I did. U can just grind the cover off the short bypass piece ( Held by few tack welds) and thats it. Open all the time. Beautiful noise, especially when u get on the throttle.
