If you put the rest of the prodrive exhaust on the car will breath easier and will give more power once it has been mapped. At this point changing the fuel pump is advisable, to ensure sufficient fuelling thus preventing problems in the future. Have you looked at other exhaust systems as they may be cheaper also look in the group buy section (Hayward andScott) and the private sales part on here for possible bargains

at the moment all i can afford is to fit the full prodrive exhaust will the car run better with this on once i take the subaru one off ,
cheers beanys
