This Flowmaster® FlowFX® cat-back exhaust system for the 2011-2018 trucks with the 6.2-liter V8 engine is manufactured using durable 409 stainless steel throughout and features single 3.50-inch to dual 2.50-inch mandrel bent pipes for better exhaust gas flow, and a FlowFX "straight-through" muffler is used for a moderate sound level and maximum performance. Maximum increases on the dyno revealed +11 hp and +15 lb-ft at the rear wheels. This system exits out both sides, behind the rear wheels with 4.50-inch black ceramic tips for added style and a custom look.

Backed by Flowmaster's Lifetime Limited Warranty.
