Has anyone tried the Kreis-seig Valvetronic Exhaust (Titanium &/or S Steel) on their 360 CS? The Kreis-seig Ti is $20k so I doubt many would have gone ahead with that but nontheless... I know of someone with a Kreis-seig S Steel on an E46 M3 and it sounds absolutely AMAZING! If anyone does have it on their CS or even "normal" modenas please post pics of it and perhaps a sound clip or two. Thanks.
