Thanks gents, interesting feedback. I have read of the 4700rpm transition but this doesn't seem to be the case on my car.
@TdMthe only difference being that I want it loud all the time with the sport button on( and quiet until high revs with sport off) 😄 It sounds silly to have it quiet as you pootle along, then suddenly get loud as you get marginally faster (it feels 'fake' if you know what I mean?). And it's still very loud not in sport mode (louder than I'd prefer).
The sport button at the moment basically turns it into drone on the motorway on/off
@agentdr8thanks for this. It all makes sense, however the last paragraph seems to not apply to my vehicle, which is the bit that I'm thinking is odd.
I'm going to try putting the stock exhaust back on in the next few weeks anyway, so will keep an eye on this and if it behaves the same way, and give you an update
