This is Alvin from Borla Performance Industries in CA. Borla is looking for a 2011-12 QX56 for exhaust development at our R&D facility in Oxnard, CA. Timing is immediately for 2-3 weeks duration. In return the owner will receive our new exhaust system installed at no charge along with the original exhaust. If you own this vehicle and live local to our facility, please send a PM. Thanks for your time!
