i dont have a video to hand but i might be able to get one tomorrow
basically it is still fairly quiet at idle nice deep bub, bub, bub, bub,, quite a deep raspy rev when you blip the throttle, nice and deep when pulling away quite a loud but not ott growl when accelerating hard and when the second tubbie comes online wow:d
i did do a back to back / before and after sound recording but the quality was that bad i binned them
i generaly dont hit boost cut, ok it doesnt on a hot day i get about 13.5psi and on an average day about 14psi. i have hit boost cut once and it scared the crap out of me it was about 2 weeks after fitting the decat and late on a cold night so i'd say a one off i have a greddy bcc to go on when the 1st decat is ready:D and a rr lol
oh and the supe sound half decent with only the 1st cat and nothing else;) likes to pop and spit tho:D
