I've got a used Fujitsubo Y-Pipe back exhaust along with a Stillen Y Pipe which I'd be willing to quick sell for £650.
Worth over £1.5k so some decent savings for you, can include free shipping along with a brand new hardware kit (all fresh gaskets, bolts and nuts).
The Stillen Y-Pipe has no flexi's, meaning there's no failure points, it'll outlast the ownership of the car.
Drop me a PM if you're interested and we can sort something out.
