| Think Weeksy getting confused with exhaust systems,my 2000 748r has as standard ali 45mm termi's .50mm came with the 748sps in the crate.2000 748r came with none but to get the best out of the 2000 748r'on, you had to fit a full 50mm system(mainly top end).Just fitted 50mm Ti Termi's to my 2000 748r.These fit over the upright pipes rather than inside.Maybe later model 748r had different diameter headers but don't think so.Pt numbers for '00 model and '02 model headers the same,so exhausts will be the same.996/998r had 50mm pipes as standard i think? |
