Morning all and happy Easter,
The back box pipe on my FSI has rusted through just behind the sleeve clamp that joins the mud box to the back box (where the hangar attached). It completely snapped the pipe in half so not repairable.
I think the easiest route is to replace the whole back box and sleeve clamp. As seems to already have been identified on here...the FSI back box doesn't seem to be available anywhere anymore.
So the options seem to be:
1. Buy the 1.4 back box and adapt the 50mm FSI centre pipe to the 45mm 1.4 pipe.
2. Buy a universal free flow back box from power flow or cherry bomb or some such.
Any thoughts from anyone. My main concerns are changing the torque or fuel economy characteristics of the FSI from changing the back pressure.
