I've got a custom exhaust that came with the car - all stainless and is loud. Sounds lovely, but was a bit loud for me on trackdays.
It's manifold back - has custom decats, y pipe, small resonator and small backbox. The flexis in the y pipe could do with replacing - or getting rid of (ie weld in a bit of straight pipe instead), but guess that depends on how low your car is. There is a repair on one of the flanges too I think.
Let me know if you're at all interested and I'll try and get some pics and more details.
