Here's a quick video of the Dinan exhaust note with the vehicle under load. I'll make a better one testing various aspects later on. But for now this should give some idea of how it sounds. This was taken near the exhaust tip with a GoPro Hero2 camera using its internal mic. (so sound won't be perfect) Sorry but it's been windy here all week.
I think it has a deeper/racier exhaust note than the stock setup.
