Does anyone know the standard bore size for the above please? i bought a new Scorpion turbo back ss exhaust around eight years ago but have decided to sell the cat back and i've just measured it and it only seems to be two inch, i thought standard was 2,25 and i expect everyone now wants 2.75 or 3.0,
Thanks.
