Need Help With Exhaust Reducer

[caphj7]

i have just brought a rage st3 backbox and it has a 2 inch input. i need to get a reducer the garage said in order to fit it. does anybody know what size the piping is behind the backbox so when they cut it off then can just put a reducer in place and fit it all up?? i really need help with this as i have tried to find it everywhere. thanks adam

Just get under the car and measure it. Fairly sure it's a standard diameter, so any decent exhaust place should have a reducer.

you will prob have trouble finding one as the k10 runs such a small bore
