a full sytem is usually from the cat back i.e. does not include the decat.
They decrease back pressure NOT increase.

it's usally bigger than ur existing exhaust so there's more free flow and dja's right it's from the cat backwards.

Doubt if they'd supply u with a de-cat pipe because you need a cat to pass your MOT

Of course they will sell you a decat pipe!!
You will have to put the cat back on for MOT's though,or have a very nice MOT bloke!!

yer janspeed exhaust will have a larger exhaust bore diameter - therefore alloughing more gas to pass through it
full system means cat-back i.e. it starts where the cat ends
not sure if janspeed do a cat replacment pipe, they might do, i know magnex do for £55 i think
