The MagnaFlow Street Series Cat-Back Exhaust for 2009–2020 Nissan 370Z with the 3.7L V6 is a direct-fit replacement system that tunes the car’s tone and flow. It uses mandrel-bent 2.5in main piping with three straight-through mufflers and a dual split rear exit with 4.5in polished welded-on double-wall tips. The kit replaces stock components from near the catalytic converter and balances resonant exterior sound with manageable interior levels.
