Wicks Aircraft Supply has added Power Flow Tuned Exhaust Systems for the Cessna Skyhawk and Cardinal to their list of products for GA aircraft. Power Flow’s system replaces a stock exhaust unit with an FAA certified, performance enhancing asset. The design enables the engine to breathe better and develop closer to its actual rated horsepower, providing performance results similar to installing a bigger engine. Each system comes with an installation hardware kit and can be traded out in about half a day. The systems cost from $3,725 to $4,425 and come with a 60-day money back guarantee and full one year/500 hour warranty. In addition, Wicks carries systems for the Piper PA-28 series, the Mooney M20 and Grumman AA-5 series.
