Hello chaps I’ve had my Copra for a month or so now, and when I stick it into sport or cupra mode, there’s some nice pops and bangs from the exhaust when letting off at around 3500 rpm. Great! But it only lasts so long. After 5 mins or so, the pops and bangs stop, and I have to go back and select sport (from cupra) or vice versa, and then I get another 5 mins worth till they disappear again? Any ideas?
