Well finally got a Magnex and got it fitted to the car. First off DC Performance said they couldn’t get one then put their prices up online the following day... managed to source from a company via eBay (who also increased their advertised price the day after I ordered).
Zorst came, my mechanic grumbled and swore a lot and ended up having to trim bits and open one pipe up. Anyway, he said the fitting was gash but once fettled it looks and sounds great. Not had chance to drive the car yet though...
Anyway, just be aware it might not bolt straight on but worth the effort and I sold my old exhaust on eBay too.
