MagnaFlow 15181 Street Series Stainless Cat-Back Performance Exhaust System

The MagnaFlow 15181 Street Series Stainless Cat-Back Performance Exhaust System is a complete cat-back replacement that delivers dyno-proven power gains alongside MagnaFlow's signature resonant, throaty exhaust tone. Engineered from the catalytic converter rearward, this system replaces all factory exhaust components with free-flowing, high-performance stainless steel hardware.
