Hi guys, i'm currently in the process of talks with a local exhaust specialist... they quoted me figures of around £200 though for a stainless box similar to the original setup. Although i'm looking really for something a little less silenced and better designed but I need to go down there and have a proper chat.
Since the initial chat I have been currently designing an assembly to send a few places for pricing. I have the exhaust flanges done and I almost have a very nice 2-1 dual 1.25" inlet 1.5" outlet collector piece designed.

Its a shame the BIS engine takes up so much space as a turbo manifold would be nice to start thinking about but creativity and a hole in the back shelfwould definately be required
