These OEM units contain dense ceramic substrates that create significant turbulence and backpressure, especially as RPMs climb toward the VQ35DE's redline. This restriction forces the engine to work harder during the exhaust stroke, increasing exhaust gas temperatures (EGTs) and robbing the vehicle of potential horsepower and torque. Over time, these ceramic cores can degrade or clog, further hindering performance and altering the engine's thermal management capabilities.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis straight pipe kit is engineered from high-grade T-304 stainless steel, featuring computerized mandrel bends that maintain a consistent 2.50-inch internal diameter throughout the entire geometry. Unlike traditional crush-bending, which narrows the pipe at the apex of the curve, mandrel bending ensures laminar flow and minimizes internal drag. The pipes include dual O2 sensor bungs to accommodate factory sensors and are finished in a chrome-polished coating for superior oxidation resistance and heat tolerance.

Finished with a 3-stage polish, the stainless steel offers superior corrosion resistance while optimizing exhaust scavenging to maximize the engine's true mid-range torque and aggressive exhaust resonance.\u003c\/p\u003e\n  \n\n  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2008-2011 Nissan 370Z \/ Infiniti G37\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eVQ37VHR \/ Z34 \u0026amp; V36\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e332 hp \/ 270 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUl106FU85LL437FU\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eFor Nissan 370Z Z34 2009, 2010, 2011 3.7L V6 VQ37VHR\u003c\/li\u003e\n    \u003cli\u003eFor Infinity G37 V36 2008, 2009, 2010, 2011 3.7L V6 VQ37VHR\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Nissan Performance Caliber\u003c\/h3\u003e\n  \u003cp\u003eEngineered for the JDM tuning environment, this race pipe maximizes the volumetric efficiency of the VQ37VHR, delivering the unmistakable aggressive V6 resonance, increased top-end power, and the sharp throttle response required for track days and spirited driving.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48205346963704,"sku":"DS-EI4SF14V8","price":259.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-race-pipe-for-nissan-370z-infiniti-g37-2008-2011-1.webp?v=1775588586"},{"product_id":"shorty-headers-for-nissan-armada-pathfinder-titan-infiniti-qx56-2004-2015-5-6l","title":"Shorty Headers for Nissan Armada Pathfinder Titan Infiniti QX56 (2004-2015) 5.6L","description":"\u003ch2\u003eHigh-Flow Shorty Headers for 2004-2015 Nissan, Infiniti Armada, Pathfinder, Titan, QX56\u003c\/h2\u003e\n  \n  \u003cp\u003e\u003cstrong\u003eDirect Bolt-On Exhaust Upgrade:\u003c\/strong\u003e Replaces the restrictive cast-iron factory exhaust manifolds on the VK56DE to reduce exhaust backpressure, improve cylinder scavenging, and increase overall horsepower and towing torque.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Stock VK56DE Exhaust Shortcoming\u003c\/h3\u003e\n  \u003cp\u003eThe factory cast-iron exhaust manifolds equipped on the 2004-2015 Nissan and Infiniti 5.6L V8 models are notoriously restrictive and prone to structural failure. Built primarily for mass-production cost savings and stringent emissions packaging, the OEM manifolds suffer from poor internal airflow dynamics. The rough cast internals create significant turbulence, leading to excessive exhaust backpressure and elevated exhaust gas temperatures (EGTs) near the cylinder head. Over time, these extreme, localized heat cycles cause the factory cast iron to warp or crack. This inevitably results in audible exhaust leaks, compromised oxygen sensor readings, degraded fuel trims, and noticeable losses in low-end towing torque.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThese Flowtech upgraded shorty headers resolve the inherent flow limitations of the stock VK56DE cast manifolds by utilizing precision 1-5\/8-inch mandrel-bent primary tubes. Mandrel bending ensures the inner diameter of the tubing remains entirely consistent through every curve, eliminating the turbulent pinch points found in the factory units. This optimized tubular geometry significantly improves exhaust gas velocity and cylinder scavenging, allowing the 5.6L engine to breathe efficiently. At the cylinder head interface, the headers utilize 3\/8-inch thick laser-cut steel flanges to ensure a completely flat, warp-resistant mating surface. This robust flange design prevents the dreaded exhaust leaks common to these trucks, maintaining structural integrity even under heavy towing loads. The system includes premium-quality replacement gaskets to ensure a reliable, long-lasting seal upon installation.\u003c\/p\u003e\n  \n  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2004-2015 Nissan, Infiniti Armada, Pathfinder, Titan, QX56\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eVK56DE 5.6L V8 \/ A60, WA60, JA60\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e317 hp \/ 385 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2004-2015 Nissan Armada (5.6L V8)\u003c\/li\u003e\n    \u003cli\u003e2004-2015 Nissan Pathfinder (5.6L V8)\u003c\/li\u003e\n    \u003cli\u003e2004-2015 Nissan Titan (5.6L V8)\u003c\/li\u003e\n    \u003cli\u003e2004-2015 Infiniti QX56 (5.6L V8)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Nissan Truck Durability Standard\u003c\/h3\u003e\n  \u003cp\u003eDesigned for the rigorous demands of half-ton towing and off-road payload capacities, these shorty headers provide the thermal stability, leak-free reliability, and low-end torque required to maximize the utility of your VK56DE-powered truck or SUV.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48363425104120,"sku":"DS-ENK7NGFAH","price":499.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/shorty-headers-for-nissan-armada-pathfinder-titan-infiniti-qx56-2004-2015-5-6l-1.webp?v=1778565146"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/collections\/INFINITI-EXHAUSTS.jpg?v=1771103432","url":"https:\/\/performancechiptuning.com\/collections\/infiniti-exhausts.oembed","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
