MagnaFlow 15694 Street Series Stainless Steel Cat-Back Performance Exhaust System

The MagnaFlow 15694 Street Series Cat-Back Exhaust System is a performance exhaust upgrade built from corrosion-resistant stainless steel using CNC precision robotic manufacturing. Designed for enthusiasts who demand both power gains and an aggressive exhaust note, this direct-fit system replaces everything from the catalytic converter back.

Iconic MagnaFlow Sound:

The Street Series is tuned to deliver the resonant, throaty tone MagnaFlow is known for, striking an engineered balance between a comfortable interior sound level and a performance-oriented exterior note. Sound levels are tested against SAE J1169 standards.
