Whiteside's super hot CTS-V coupe makes 670 HP thanks to a host of enhancements, including ported heads, custom cam, Lingenfelter intake, KDI Innovations heat exchanger (and pump), Lingenfelter upper & lower pulleys, Kooks headers into catted mid-pipes, and Corsa Touring exhaust. They tuned it to handle too, with a full set of suspension bushings, lowering springs, and Michelin Pilot Super Sport tires. They even powder coated the brakes and upper supercharger cover. Their 20-inch Forgeline RB3C-SL Stepped Lip wheels are finished with Titanium centers and Brushed outers.
