Performed the open exhaust valve little more involved with the wiring than I thought but not too bad. Need to remove the under tray to get access. Just 10mm bolts pretty simple. The exhaust note is definitely more pronounced and little drone in comfort and eco mode at light throttle. I will get a vid as well for sound

Did you notice if the higher RPM cold start seems to last longer than before the valve mod? May of just be me not remembering but if the ECM is trying to warm the cats it may take longer to reach idle RPM with the valves open. Reminds me of the old days when we had a carb with choke and the closed choke had to warm before opening and slowing the cold start RPM.

It’s about the same it was just so quiet before

Anyone do res delete at a shop or straight pipe the muffler? Has anyone actually done an exhaust upgrade and comment on it? Need some feedback

Do not delete resonator if your m60i has msport exhaust package . I did delete resonator today and the sound turn out suck I wish I didn’t do it
