I am debating on whether or not to sell my Akrapovic GT4 full catless/titanium exhaust. It is still wrapped, brand new it its box. I have had it sitting in my garage for over 4 months. I paid almost 6K for it shipped to Hawaii (which is a steal considering the exclusivity of the system), so I would let it go for $4,800. If anyone is interested, let me know. If no one wants this exhaust I'll probably get it put on after the new year with an ESS tune.
Below is a link with some information on this rare piece from Akrapovic. This is not the typical EVO exhaust most people have, it is a full blown race system that North American customers aren't supposed to have. It's essentially the same system but without resonators or catalytic converters, and the rear section is actually lighter. To my knowledge this is the same system used by BMW race teams in Europe.

*If any of you are concerned about noise, I spoke with the handful of owners who have this complete system in the US and they agree that the full catless system is surprisingly quieter than my current Eisenmann Race.
*The system also came with heat wraps for the differential/axle shafts.
