Yup the 3 prong pipe is about £35 from the stealers as i had to replace mine when i bought the car last year. I also found a few other hoses were very soft and old so have replaced them too to help the system work effeciently.
I replaced my TIP with a cheap ebay jobby as it was really soft too so found a few other bits to replace then too.
As your not a million miles away (i`m in Southampton) can always show you on my car if your around one evening
