hey guys

dont know if its a problem but ive got a dc2 with a fujitsubo rm01a catback...(stock headers & cat) but i find it really loud inside the car...outside its no so bad but inside its ridiculously loud. was professionally installed and i took it back and he reckons its fine so dont know if its normal or 'loud'
