oh please dont ask me technical stuff - I'll just embarass myself
Exhaust has 3 sections - 2 on yours got Cat Convertors in ( downpipe - from Turbo down and centre section - runs virtually the length under your car from front to backbox ) - you need to take those off and buy a downpipe and centre section without cats in........I would recommend a Blitz nur spec ............and get the backbox to go with it as well................brand new will cost probably half a kidney but if you look on www.scoobyworld.co.uk then you will get true idea of prices
