Cutting in Exhaust Bypass Valves?
I have a 14 e63 wagon. I love it and bought it new in 14. 4 great years in a tuned wagon. The valve exhausts look great but the stock one is fine and the price of a valve exhaust for the only real benefit being the valves is too extreme. anyone tried to cut in valves?
