   Am i right in thinking Citroen sell one of these without a silence/cat in?
   
   It would be like a 'race pipe', wont be stainless steel or anything but still do the job.
   
   Anyone know a part number? Or Price

   if you have a mk2 and put a mk1 down pipe on it then will decat your mk2
   
   suppose it will be like having a cheap 4-1 manifold lol

   they do yes
   its off the mark 2 1.0 models with the cat in the manifold
   
   and its a smaller diameter than the supersprint and other straight through systems at 1.75" not 2"

   After abit of searching .... I think the one i'm after might be off a mk2 furio.
   
   Could someone confirm this?
   
   
   Edit:
   Cheers alex,
   
   Whats the one for furio's like? I need a 2" ideally.. Well a 2.5" if i want perfect match to my backbox but that wont happen lol.

   is the same iirc
   a 2.5 will be too big for an n/a motor imo (unless its boxed like a btb)
   
   itll do the job tbh but not as good
   the bends will be slightly crushed in ect but to functio to decat the car and free it up a bt itll work tbh

   Ok mate, its not for performance really anyway as my cats in the downpipe. Just to replace my current rusty one.
   
   Any idea's on a backbox that will fit on a 1.75" ?

    2001 furio pipe mate they are around 13quid from euro car parts, straight through from manifold to back box.
    1.75" iirc so not quite as big as a supersprint
