You're dead right Dave it doesn't sit perfectly square, it does look worse in that pic though but its the only 1 i have
You're right about the bolt on flanges not giving enough room for movement if not fitted right, I had to make up 3 x 1/2" spacers to get the tail pipe to actualy line up with the hole in the bumper
But from what i've heard that isn't a problem with the small turbo.
