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

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!!

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

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

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