is there any big retailers or "speed shops" in Seattle Washington area? im looking to by kooks headers and a corsa catback among other things for my V. i live in BC Canada and would like to shop in the US since our dollar is coming up to par. colsest to Vancouver would be the best, im gessing frieght costs on heavy and larger items like exhast parts would be high coming from the east coast or from southern states.
thanks for the help.
