I bought it directly from Banks. It was the exhaust system, transcommand and the new chip for the engine. The cost of the system, including shipping to Phoneix, was about $2400. I had it installed by a guy there who has been doing only that for the last 6 years. It took him about six hours and cost $650. If I'd had it done in Wa, the cost would have exceeded 4K. So I figure I did quite well.
