Mufflerectomy? How much and where?

[d.mellor]

Basically I'm after a pipe in place of my back box (a mufflerectomy) on my mk5 tdi. I already have the twin tailpipes so really all I need is about a meter of pipe bending and welding to the tailpipes.

Anyone no a ruff price or anywhere to get it done?
Anyone else had this done too?

Thanks
