Just an update for everyone...few days ago I pulled the plug instead of doing this spring wire mod which I didn't really like the idea of, but just an update that I really like the car better this way and a cool plus I didn't see anyone mention is that when you just leave the car in comfort mode you get full exhaust note from both sides but no burble when letting off gas but it is really cool to have full exhaust note in comfort mode. I only drive in comfort mode for like a day after I get fuel just to see how high I can get my MPG or if im doing 2+hr road trip which I then use eco pro.
So you get full exhaust note after car is on for 30-40 secs after a cold start, and you get full exhaust note in comfort mode but minus the burble.
