Banks' 3" all-stainless-steel, mandrel-bent Monster exhaust system bolts behind the catalytic converter, cutting backpressure by 92%, optimizing airflow, improving engine life, increasing fuel efficiency and adding power. The low-restriction, 3" straight through Monster muffler more than doubles the stock muffler flow and provides an authoritative, yet civil exhaust sound. The finishing touch: a mirror-bright 5" polished-stainless double-walled tailpipe tip with a rolled edge. Vehicle-specific for easy bolt-on installation. Fully compatible with Nissan's factory warranty, the entire system is covered by Banks' Lifetime Ltd. Warranty.
