Scirocco Central

Hey bro. Love what you have done with your scirocco. Im think of the same and want to take it to stage 2 but got a bit of an issue. I have got a scorpion cat back installed and for stage 2 i need a turbo back and ai was thinking of getting a downpipe and a sports car instead of the full system but I cant seem to find any online for the 1.4 scirocco. Do you know anywhere incan get one or if anyother car part might fit mine?
Also what do dogbone inserts and bushings do?

I am planning revo stage 2 in the near future. I am saving up for a downpipe too. Very hard to find those with sport cat fitted. Go check BullX, they make dowpipes for the 1.4 tsi with 100 or 200 cell sport catalyst.
