Exhaust Chat, do we get OPF/GPF error?

Will do! Probably stainless, not sure what benefits titanium has over stainless other than weight and strength, I imagine noise is similar?

Dissapointing that you still got a check engine light with the module, it shouldnt really matter if it's for a bmw provided it's for a B58...

So another 800km of mostly mountain driving and still no check light and this car is now what I expected when I bought it. Lots of burbling and lift off pops and bangs when you want it in sport, but quiet and civilised in normal. Only negative is virtually no difference at fast motorway speeds, 90mph plus, previously it would quieten right down in normal.
