It's an Amuse R1 Titanium exhaust so it's hardly @*!#, done nowt twice yet either. All of my jobs once fitted are spot on. You can only buy things second hand based on the photos you are provided, I could have driven the 400 mile round trip to go and see it but who realistically does that? The lad has already offered to reimburse me the cost of the rework so there's no massive issue other than me having to find somewhere that tig welds titanium.
All of the other welds are fine from what I can see, I'm a pipefitter by trade so I know what I'm looking for.
