if you already have the exhaust from a scoob on it get the oval magnex they did for the scoob 
Im having to mod the backbox so it will fit the golf so it just the tailpipe I need otherwise id have to mod the new one as well. I trying to keep costs down that why I bought the 3" subaru exhaust using it has cost me £70 for a full 3" turbo back including sports cat plus my time making it so far.
Jack I dont know where you find these things from! Loving the cat one might get it for my missus

an r32 breaking you might get the exhaust am bumpers from
Would love to mate but ive just spend a lot building the engine, saving for the map now so cant afford to buy bumpers at the mo thats why a cheap tailpipe will do for now.
