Muffler Exhaust System for Nissan Titan (2007-2015) 5.6L 139.8" Wheelbase

Direct-Fit Complete Muffler Exhaust System with Catalytic Converters for 2007-2015 Nissan Titan (A60)

What it Does: The complete muffler exhaust system replaces the entire factory exhaust assembly from the manifold flanges back on the 2007-2015 Nissan Titan to eliminate exhaust leaks, restore quiet OE-level sound attenuation, and ensure correct emissions compliance.

The Stock Nissan Titan Exhaust System Deterioration

The factory exhaust on the first-generation A60 platform suffers from severe thermal fatigue and environmental corrosion. Over time, road salt and moisture degrade the low-grade factory steel tubing, seams, and flange junctions, resulting in cracked catalytic converter bodies, blown flange gaskets, and rusted-out muffler chambers. These pinhole leaks introduce unmetered ambient air near downstream sensors, causing erratic lambda readings, false catalytic efficiency diagnostic trouble codes (DTC P0420/P0430), cabin exhaust fumes, and harsh acoustic drone under towing loads.

The Engineering Solution

This direct-fit replacement system is engineered from heavy-gauge 409 stainless steel, providing superior resistance to thermal cycling, scale buildup, and chloride-induced pitting. Smooth mandrel bends maintain uniform inner pipe diameter throughout the routing, eliminating the turbulent flow restrictions common to crushed factory tubing. The manifold-back assembly integrates replacement front catalytic converters featuring heavy-duty ceramic honeycomb substrates and precision-welded O2 sensor bungs. Factory-indexed mounting brackets, flanges, and hangers enable a direct bolt-on installation without cutting or torch work.

Frequently Asked Questions & Fitment Warnings

Does this fit the A60 Titan?

Yes, this is a direct fit for the 2007-2015 Nissan Titan equipped with the VK56DE engine. For model years 2008 through 2015, this system only fits configurations with a 139.8-inch wheelbase and will not fit long-bed or non-139.8-inch chassis.

Is this system CARB-compliant for emissions testing?

No, this assembly is designed for Federal EPA 49-state OBD-II compliance and is not legal for sale, installation, or use on vehicles registered in California, Colorado, New York, or Maine.

The Nissan Truck Durability Standard

Built to handle heavy tongue weights, off-road torsional chassis flex, and grueling hauling cycles, this complete 409 stainless assembly restores the rugged, rattle-free exhaust durability demanded by full-size work trucks.
