2004 SS/R 5.3 liter with a true custom dual exhaust system. This system features a Flo~Pro crossflow muffler which equalizes and balances the exhaust system internally to provide maximum horsepower with optimum back pressure. No need for two heavier mufflers. No need for "H" or "X" pipe. This muffler does it all! This good looking and awesome sounding system is finished off with a gorgeous set of Corsa "viper" stainless steel tips. Horsepower gains of 14 and fuel savings of around a mile per gallon! Get your SS/R done right the first time at Kinney's muffler shop. On the web at kinneysmufflershop.com (less info)
