MagnaFlow 15679 Street Series Stainless Cat-Back Exhaust System Single Exit

The MagnaFlow 15679 Street Series Cat-Back Performance Exhaust System is a direct-fit, stainless steel exhaust upgrade engineered to deliver dyno-proven power gains alongside MagnaFlow's signature deep, resonant exhaust tone. Constructed from 100% stainless steel and manufactured in the USA, this cat-back system replaces all stock exhaust components from the catalytic converter rearward.

Performance & Sound:

• Mandrel-bent 2.5-inch main piping maintains consistent diameter through every curve for unrestricted exhaust flow and reduced back pressure
• Single straight-through muffler features a stainless steel perforated core, end-to-end, with no baffles or restrictive chambers
• Stainless steel wool core insulation absorbs excess noise and shields against high exhaust temperatures
• Tuned for moderate exterior and mild interior sound levels — deep and throaty under throttle, refined inside the cabin
• Dyno-tested to verify measurable increases in horsepower, torque, and fuel efficiency
• Noise levels tested and balanced to SAE J1169 standards
