Extremely happy customer all thanks to A+ customer service from RSD. I'm in Australia and it arrived 5 days after ordering!!! only problem was that it had been damaged on the trip here. RSD sorted it all out with no problems at all!! In terms of the exhaust.. its amazing!! the sound is incredible for an axle back!! its deep and makes the car sound like it should!! look here for a video of a few flybys at my first track day
