Flowmaster proudly introduces our new 409S stainless steel exhaust for these vehicles equipped with the 4.7 and 5.7 liter V8 engines. Part number 817400 is the American Thunder system developed specifically for these popular vehicles. Featuring our 70 Series Big Block II muffler and mandrel-bent tubing throughout, this dual tailpipe exhaust has a moderate sound inside and out, as well as the performance and mileage gains you expect from Flowmaster. For a finished look, the tailpipes exit side by side and feature polished, 3.00” diameter Flowmaster-embossed tips. Bolting on behind the OE catalytic converter, this exhaust system is 50-state emissions legal and is manufactured entirely in the USA.
