+1 on the sound on clips, before I changed exhaust (rear pipes) It was a mad sound at 2k rpm but on clips with different camera setups it doesnt come through! Think it's to low Hz for it to be picked up or my laptop didnt understand what to do with it!
(might try that again actually) love the sound as much as I can hear and perfect delight noise from the driver at the end
10hours... some cost though, might go down that route next year if I'm bored!
