mike519, have you heard other exhaust options? I am the first to agree that the stock setup is way too anemic sounding, but when I put on the RE Diablos, I couldn't stand the interior drone. Someone correct me if I'm wrong, but the SS drones also, except for the PowerLoops from what I recall.
The RE Drone was unbearable to me, especially with the top down (which is pretty much the only way I drive the car). RE's own literature calls them "drone free"; I'm not the only one that thinks those things drone like crazy. Just saying -- I'd hate for you lug all this stuff back, just to have to put it up for sale.
