Engineered from 3-inch 409 stainless mandrel-bent tubing with a 3.50-inch polished T304 stainless round slash-cut clamp-on tip, the Gibson 612213 delivers a deep, aggressive tone while adding real, dyno-proven horsepower and torque right where the 5.6L Endurance V8 needs it most. Direct bolt-on installation with a flange connection to the converter no welding, no cutting. Made in the USA and backed by Gibson's lifetime limited warranty.\u003c\/p\u003e\n\u003ch4\u003eWhy the Gibson 612213 Outperforms Stock\u003c\/h4\u003e\n\u003cp\u003eThe factory exhaust on the Nissan Armada and Infiniti QX56 is engineered for compliance and quiet operation not performance. The Gibson 612213 replaces that restrictive OEM system from the catalytic converter back with free-flowing 3-inch 409 stainless mandrel-bent tubing that holds consistent diameter through every bend. The result is reduced backpressure, improved exhaust scavenging, and measurable gains right in the 1,800–3,000 RPM range you use every day for acceleration, passing, and towing.\u003c\/p\u003e\n\u003cp\u003eDyno testing consistently shows the Gibson 612213 adds an average of \u003cstrong\u003e10–15 horsepower\u003c\/strong\u003e and \u003cstrong\u003e15–20 lb-ft of torque\u003c\/strong\u003e over the stock system. And because the Gibson Superflow muffler exits behind the rear tire, interior drone stays minimal aggressive sound outside, quiet enough inside for daily driving and long hauls.\u003c\/p\u003e\n\u003ch4\u003eGibson Superflow Muffler\u003c\/h4\u003e\n\u003cp\u003eThe heart of the Gibson 612213 is the Gibson Superflow muffler an 8-inch round baffled and chambered design with no internal packing material. No packing means no breakdown over time. Packing-based mufflers lose their tone as the material degrades; the Superflow's all-metal baffled chamber construction sounds great on day one and stays that way. The 24-inch body runs a 3.00-inch offset inlet and 3.00-inch offset outlet, sized to match the 3-inch tubing throughout the system for consistent flow velocity from converter to tip.\u003c\/p\u003e\n\u003ch4\u003eT304 Polished Stainless Tip\u003c\/h4\u003e\n\u003cp\u003eThe 612213 ships with a 3.50-inch round slash-cut tip crafted from T304 polished stainless steel. T304 is a higher-grade alloy than the 409 stainless used for the tubing chosen for the tip specifically because it holds a mirror-quality polish and resists the heat discoloration that standard stainless develops over time. The clamp-on design lets you dial in the tip's depth and angle before final tightening, so it looks right from any angle behind the Armada or QX56.\u003c\/p\u003e\n\u003ch4\u003eFitment 2004–2011 Nissan Armada \u0026amp; 2004–2010 Infiniti QX56\u003c\/h4\u003e\n\u003cp\u003eGibson 612213 fits both the \u003cstrong\u003eNissan Armada\u003c\/strong\u003e and the \u003cstrong\u003eInfiniti QX56\u003c\/strong\u003e these two full-size SUVs share the same F-Alpha body-on-frame platform and 5.6L VK56DE V8, so the same system fits both nameplates.

The Infiniti QX56 (2004–2010) is built on the same Nissan F-Alpha platform as the Armada and shares the same 5.6L VK56DE V8 and exhaust routing. The Gibson 612213 is a confirmed direct fit for the QX56 through 2010. Note: the second-generation QX56 (2011+) switched to a unibody platform and is not covered by this part number.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat size tip does the Gibson 612213 include?\u003c\/strong\u003e\u003cbr\u003eThe 612213 ships with a 3.50-inch round slash-cut tip made from T304 polished stainless steel.

No cutting the factory pipe is required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Gibson 612213 legal in California?\u003c\/strong\u003e\u003cbr\u003eAs a cat-back exhaust system, the 612213 installs behind the catalytic converter and does not affect any emissions control equipment. The system is street legal in all 50 states.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill the Gibson 612213 void my Armada or QX56 warranty?\u003c\/strong\u003e\u003cbr\u003eNo. Under the federal Magnuson-Moss Warranty Act, an aftermarket part cannot void your factory warranty unless the manufacturer can prove the aftermarket part directly caused the specific failure being claimed.

Gibson designs this system to be quieter inside the cab than comparable performance exhausts you get an aggressive tone outside without excessive drone on the highway or during towing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between the 612213 stainless and the 12213 aluminized?\u003c\/strong\u003e\u003cbr\u003eSame fitment, same Superflow muffler, same performance. The 612213 uses 409 stainless steel tubing and carries a lifetime warranty against rust and corrosion.
