    you will benefit more from a full exhaust system this will give you high flow downpipe to a sports cat (remove the cat altogether for more power but this will make the car smoke its nackers out) (ever watched truck racing on tv????? smoking)
    i advize a full miltek system from turbo back roughly 540gbp
    or if your limited to funds you could get another 30 to 40 bhp by removing the cat...advancing the pump by 10 degrees (dont go any further that 10 degrees) and up the boost pressure on the actuator arm..

    most insurance companies won't touch you with a decat - even greenlight who are very mod friendly stay well clear for some reason.

    you can decat it but you will see more benefit from sports cats but if your crude enough cut your cat in half remove your pm from the metal and reweld the cat back together..
    diesels use back pressure to combust so if you go this route or decat completely you will loose high end power but gain low end... also long spells at high rpm will lead to high crank temps and lots of smoke

    the reason insurance companies wont quote is you are poluting the air more with no cat

    I have a de-cat on my tds. This was done before getting it chipped and there was no noticable difference in power. Reliable sources tell me that I lost 2-3 NM of torque low down but gained 2-3 BHP up top. What I did notice however was a much nicer, slightly louder, exhaust note

    The chip is the way to go on the diesels. Huge difference in power and completely transformed the car. Was pretty sluggish stock (143 bhp and auto, over 10 sec to 60) now a lot more rapid (8.5 0-60)

    I also used a 2 pence piece to block the egr valve. Do it on the exhaust manifold side as the screws on the intake are quite short and its alloy as opposed to iron.
