MBRP · Resonator-Back · 2.5″ · T409 Stainless
The MBRP S5207409 replaces your factory resonator section back with mandrel-bent 2.5″ tubing — opening up flow + voice while keeping the OEM front section, cats, and connection flanges intact.
Bolt-on at the factory hanger locations. No tune, no check-engine light, no drone at cruise.
Built from T409 stainless steel — MBRP’s mid-tier corrosion-resistant alloy. Welded and sealed, backed by a limited lifetime warranty.
