MagnaFlow 19370 Street Series Stainless Cat-Back Performance Exhaust System

The MagnaFlow 19370 Street Series Cat-Back Exhaust System is a complete stainless steel performance exhaust upgrade engineered to deliver MagnaFlow's signature deep, resonant tone alongside dyno-proven power gains. Designed with a straight-through flow architecture, this system replaces all stock exhaust components from the catalytic converter rearward for a significant improvement in exhaust gas evacuation and engine breathing.

Built from corrosion-resistant stainless steel using CNC precision robotic manufacturing, the 19370 features mandrel-bent 3-inch main piping routed through three straight-through mufflers and exiting in a quad split rear configuration. The four polished, double-wall angle-cut folded-edge tips — each measuring 4 inches in diameter with 6.125-inch length — deliver an aggressive, show-quality appearance to match the performance upgrade.

Key Features:

• Mandrel-bent 3-inch main piping for unrestricted, full-bore exhaust flow
• Three straight-through mufflers tuned for moderate exterior / mild interior sound levels
• Quad split rear exit with four 4-inch polished double-wall angle-cut tips
• Stainless steel construction — corrosion-resistant and built for the life of the vehicle
• CNC precision robotic manufacturing ensures consistent quality and exact fitment
• 3D-scanned direct-fit design for OEM-like installation with no cutting or custom modification
• Clamp-on inlet connection — all necessary hardware included for DIY installation
• Dyno-tested to confirm real-world power and torque improvements
• Tested against SAE J1169 standards for interior and exterior noise levels
• Made in the USA

The 19370 is backed by MagnaFlow's limited lifetime construction warranty and a 1-year limited finish warranty. All required installation hardware is included. Note: Vehicles equipped with factory Active Exhaust require the MagnaFlow Active Valve Kit (part #10805, sold separately) to retain factory-style exhaust valve control.
