R53 Cooper S exhausts

Been running an R53 Cooper S since Oct last year - I stupidly ran around for the whole time with a broken exhaust bracket which has resulted in a crack in the flexipipe just below the manifold :( Unfortunately it's a single piece from manifold to cat so I've been quoted €700 to replace - I talked to autoexhausts in crumlin but it can't be cut out and replaced because it's so tight for space so now I'm in a quandry - do I replace with OE and move on, get something custom built by someone like souhans or replace with an off the shelf full system.

What would you guys do?

I've been planning a pulley kit anyway so I'm leaning towards either a custom system or full milltek or similar system depending on price.
