The T409 stainless upgrade to the MBRP F-150 Cat-Back lineup. The Armor Plus Cat-Back for the 2021–2026 Ford F-150 delivers dyno-proven gains of up to 11 HP and 8 lb-ft of torque through a 3" main pipe stepping down to a 2.5" dual split side exit — finished with two polished 4.5" tips and backed by a Lifetime Warranty.
MBRP's Armor Plus Series is built from corrosion-resistant T409 stainless steel — tough enough for daily driving, backed for a lifetime. All of the tubing is mandrel bent for maximum exhaust flow with no rippling at the bends. Bolt-on installation uses OEM hanger locations with clamps included. Note: does not fit PowerBoost hybrid models. Rudy's Performance Parts is an authorized MBRP dealer.
