These systems are designed to directly replace original mufflers using factory hangers and connections. With easy fit in mind, these units utilize mandrel bent tubing (where applicable) for maximum performance and include specially selected mufflers. Direct-fit mufflers deliver a moderate interior and exterior tone and are suited to the enthusiast who wants their performance to be heard without breaking the bank. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation.Warranty Information:Limited LifetimeBody Height: OEMBody Length: OEMBody Width: OEMCalifornia Proposition 65 Chemical Name 1: Nickel (metallic)California Proposition 65 Chemical Name 2: Chromium (hexavalent compounds)Exhaust Series: American ThunderHeat Shield Attached: NoInlet Diameter: 3.000 in.Inlet Inside Diameter: 3.000 in.Inlet Outside Diameter: 3.000 in.Inlet Position: OffsetInlet Type: Single OffsetMain Piping Diameter: 3.000 in.Material: Stainless SteelMuffler Count: 1Muffler Series: 50 Series HDOutlet Diameter: 2.500 in.Outlet Outside Diameter: 2.250 in.Outlet Position: DualOutlet Type: Dual OutletOverall Length: OEMShape: OvalSound Level: ModerateSystem Type: D-Fit MufflerTip Quantity: 0Title: Flowmaster 817568 Direct-fit Muffler 409S - American Thunder - Moderate SoundWARNING CA Proposition 65: YesWARNING CA Proposition 65 Message: WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
