This system is manufactured using durable 409 stainless steel tubing and features 3.00-inch to dual 2.50-inch mandrel bent pipes for better exhaust gas flow. A 50 Series Big Block muffler is used for a moderate to aggressive sound level and superior performance. Dyno testing revealed maximum increases of 13 hp and 15 lb-ft at the rear wheels.
