I also purchased this exhaust (the OC one) recently from the San Francisco Lambo dealer, and had it installed, and it was just over $5k (although it's noted on the invoice that it's version 2 of the exhaust). So $4k is no longer the real price.

I'm loving it though - stock looks, but incredible sound. I previously had the Burtoni exhaust for my G, but in less than one year that POS was already RUSTING from the inside out! Stay away from the Burtoni exhausts for Gallardos!! Will post audio / video clips if anyone is interested.
