hi,
the downpipes are different and can not be interchanged, however the last two or three years they were altered, but only the back two boxes, the auto boxes were made a bigger diameter to the size of the manual so that you could use them on either of the cars. i think from memory 47mm and 62mm ring a bell, tell me if i am wrong. you will have to measure the diameter of your exhaust and see if it is the same as the 's'
