   Yes or keep your standard cat and centre pipe, then run a full length performance centrepipe. Usually works out cheaper than a decat + catback pipe.

   so keep the cat and centre pipe for mot?
   
   and the full pipe for normal, would that be really loud?
   
   links to parts please!

    that would go from the manifold to the backbox, 1 piece that removes the cat and silencer.

    Its one long pipe instead of a decat pipe plus middle section. Makes it easier come refitting CAT for MOT and stuff.
