Exhaust different in eco pro vs sport plus and with DSC all the way off
Hello! I have noticed that my cars exhaust (just a muffler delete) gets louder and pops more in eco pro than anything else, also if I turn off the traction by holding it down for 10 sec it gets louder, any clue on why??

This happens to me as well.. Eco Pro pops more at low RPM's more than Sport Mode... not sure why. Although no muffler delete, just downpipe.

In eco pro, you are in a higher gear at a lower speed, so when you let off and coast (especially downhill) you're going to decelerate slowly which provides pops.
