For reference I installed long-tube decat headers in my 2.9L 987.2 Cayman, as well as Cayman R mufflers (I think they are the same as stock mufflers), and got a nice sound out of it but my butt dyno said no real difference. Maybe I should try some intake or soft tune.

Thanks for the cut away on the muffler - I bet cutting the pipe leading into the CAT would do as much as any aftermarket muffler, removing any weight in the muffler will probably improve performance more than the improved breathing.
