Urgent help needed

Is the bore size the same for a 1200 spi and a gsi on the exhaust.

Need to know if its the same from the backbox the centre section as a magnex exhaust ends on ebay in 12 mins lol

dont think they are mate. think the gsi one has a wider diameter iirc

[napalm_27]

make it fit mate lol
i.e weld a bit of smaller pipe into it or somethink along those lines
iv got a venom bike can on mine and mates got same but a 3 bolt plate fitment on his we just got the welder out and they sound amazing

slightly different bore but just tighten them till you go purple.
