Exhaust System for Nissan Frontier (2007-2019) 4.0L Crew Cab

Direct-Fit Replacement Exhaust System for 2007-2019 Nissan Frontier (D40)

What it Does: The direct-fit exhaust system replaces corroded cat-back exhaust components on the 2007-2019 Frontier to eliminate exhaust leaks, cabin drone, and structural pipe separation behind the catalytic converters.

The Stock Nissan Frontier Exhaust System Weakness

Factory exhaust piping on the D40 Frontier deteriorates rapidly at the two-into-one Y-pipe collector joints, resonator welds, and muffler seams. Moisture accumulation from combustion cycles combines with road deicers, causing localized galvanic corrosion and rust pinholes through the thin-gauge mild steel tubing. As internal baffling collapses and the outer casing fractures, the 4.0L VQ40DE develops severe low-frequency drone, structural rattles, and hazardous exhaust gas leaks directly beneath the passenger cab.

The Engineering Solution

Fabricated from heavy-gauge 409 stainless steel, this complete replacement kit provides superior oxidation resistance and thermal fatigue tolerance over factory mild steel. Smooth mandrel-bent tubing preserves uniform cross-sectional diameter, maintaining stock scavenging velocity and backpressure profiles while preserving factory OE sound levels. Heavy-duty flanged connections and factory-located hanger prongs mount cleanly to OEM catalytic converters and rubber chassis isolators without cutting, slip-fit adapting, or welding.

Frequently Asked Questions & Fitment Warnings

Does this fit the D40 Frontier?

Yes, this is a direct fit for the 2007-2019 Nissan Frontier equipped with the VQ40DE engine and 139.9-inch wheelbase Crew Cab configuration. It does not fit King Cab models, standard short-bed Crew Cab trucks, or models equipped with the 2.5L four-cylinder engine.

Are catalytic converters included with this kit?

No, this assembly installs directly behind your factory catalytic converters using the included hardware and flange gaskets.

The Nissan Truck Durability Standard

Engineered specifically for heavy hauling and towing duty cycles, this 409 stainless assembly withstands chassis flex and sustained thermal loads without cracking seam welds.
