Mullenrm … hi
I also have a rattle, especially when cold, and still when hot, not just as noticeable. Had the dealer yesterday say it is the bracket that holds the twin exhaust pipes together just after the manifold. Design is that the entire pipe must be replaced since the bracket is part of the pipe and cannot be replaced. Does this sound like what you had? The dealer quoted me $2,900 for a new exhaust pipe!!!
