ok so here is a short story about the car. its a 1990 2.0 si prelude with the b21 in it and its dying along with the tranny, anyways i have a b20a to go in with stage 3 racing clutch etc... all kinds of goodies. my main question really is i have obx headers and down pipe i need to fit on an exhaust system to that header and what would be a good combo? i live in seattle, wa and it will need to pass emissions any input or help would be great. i have been doing research and will continue to do so ty for the help. also is there is going to be any problems with this swap as they are both prelude motors
