I have just finished it all up and started the engine for the first time since it all came apart, (full exhaust not connected) the car started right up no problem not even a wait whilst it turned over it went fine sounded very loud obviously with just a supersprint on. But not the engine is done and looking good running good. Just a quick note if you get the flexeo pipes keep both the original bleed valves as they don't come in the kit just to let you know.
