GMC Sierra Performance Exhaust - Rear - Magnaflow - Cat Back - Black - `14-`15. The MagnaFlow Street Series Black cat-back is built for 2014-2015 GMC Sierra models, delivering a tuned exterior presence with a comfortable interior tone.
Designed as a direct-fit cat-back system (MagnaFlow kit 15360), this assembly pairs durable stainless steel construction with black-coated dual split rear tips for a refined, performance-focused replacement. The system is manufactured using CNC precision robotic techniques and mandrel-bent piping to maintain flow and consistency. Expect dyno-proven power gains and a more assertive exhaust note outside the cab while keeping interior sound levels suitable for daily driving. The Street Series Black includes MagnaFlow’s limited lifetime construction warranty and a 1-year finish warranty on the coating.
