i have recently noticed that there are more pops and bangs from my exhaust, never happens under load only on overrun. really noticeable around 3k revs in any gear, is this normal at this time of year?
recently changed back to oe dump valve but still does it. 51 plate bugeye wrx with full decat inc uppipe and ecutek map
love the sound just want to make sure it is not a problem

 

from how you describe it yep normal, enjoy
