Gary,
i finally found you on here. Im pretty sure you have an OEM/orig exhaust on your car. I remember when I looked at your car at AMC that one night. It looked exactly the same as my stock exahust. I have only seen the Mclaren exhaust on a car in cardomain, and it had different tips than you do...
PS we need to meet up soon so i can check out your nav, i wanna see if I should buy it but I want to see how it works. YOu can get a listen to my exhaust too, to give you an idea. having an LSE you already have the exhaust tip cut-outs, so i woudl prob do borla as well, but i love the sound of the magnas.
