German tuner Inside Performance has revealed an aftermarket package for the BMW X6 M, including a raft of styling enhancements and a significant boost in power. That comes via a remapped ECU and a 3-inch stainless-steel exhaust with a 200-cell sports catalyst that combine to increase output from the 4.4-liter twin-turbo V8 to 700 hp and 627 lb-ft of torque, up from 555 hp and 500 lb-ft. The new flap-controlled quad exhaust system boasts 90mm quad pipes coated in a special 1000-degree temperature resistant coating in a range of colors, including matte Cobalt Gray as pictured.

Exterior mods on the "Stealth" X6 M include an AC Schnitzer-inspired wide body kit that covers the rear-door cladding, fenders and bumpers, widening the high-performance SUV by four inches and closing the gap above the wheel arches. Completing the overhaul is a carbon GTR air intakes on the hood, a blue and grey pixel-camouflage wrap, a set of 22-inch deep concave alloys from Vorsteiner, a KW suspension, and a data display integrated into the interior, digitally displaying information such as the car's boost, torque, and temperatures.
