Chevrolet Avalanche Performance Exhaust - Passenger Side Rear - Magnaflow - Cat-Back, Street Series, Single Passenger-Side Rear Exit, Polished Tip, 3 in. Piping - Polished - 10-13. This MagnaFlow Street Series cat-back is built for 2010–2013 Chevrolet Avalanche owners who want a clearer, more confident exhaust tone and reliable, direct-fit hardware.
Designed as a complete cat-back replacement from the catalytic converter back, this system delivers a moderate exterior and mild interior sound level while improving flow with mandrel-bent 3" main piping and straight-through muffler designs. The single passenger-side rear exit features polished, welded double-wall 3.5 x 5.5" rolled-edge tips for a factory-integrated look. Extensive 3D scanning during development and CNC robotic manufacturing provide a direct-fit system that installs cleanly on compatible Avalanche models. MagnaFlow’s construction and finish warranties back the product.
