Description
Mild Exhaust Note. Made in the USA and engineered to last, the Street Series Cat-Back Exhaust will give you better performance, economy and that smooth, low sound you crave. Wide-open performance, straight-through flow, unrestricted horsepower and torque—that’s the Magnaflow difference.
