2.0 exhaust system

[Rastamouse]

Hi guys,
Ive currently got a single exit exhaust on my 2.0 tdi 140 sline saloon, and i want to convert it to twin exit exhaust.
Ive just been offered a complete system off a 2.0t fsi saloon.question is do i need the cat or ar they different. Therefore meaning i just want the two rear boxes and the pipework to join them???
Your help on this matter is gratefully appreciated.
Thanks

Hi mate, no you don't need the cat, just the 2 boxes, heat shield and exhaust hangar for drivers side and a Tfsi diffuser. Look at my build thread for pics of mine.

What about connecting both boxes together??
