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. By removing the cellular obstruction of the stock cats, these pipes allow for a direct, high-velocity exit for exhaust pulses, significantly improving volumetric efficiency and delivering a raw, aggressive acoustic profile characteristic of the VQ engine family.\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;\"\u003e2003-2007 Nissan, Infiniti 350Z, G35\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;\"\u003eVQ35DE \/ Z33, V35\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;\"\u003e260-300 hp \/ 260-274 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;\"\u003eBE102AU069PS229\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eT-304 Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInlet\/Outlet\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2.50\" \/ 2.50\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2003-2006 Nissan 350Z VQ35DE RWD (Except 2005 35th Anniversary Edition)\u003c\/li\u003e\n  \u003cli\u003e2003-2007 Infiniti G35 3.5L V6 RWD\u003c\/li\u003e\n  \u003cli\u003eFits Coupe and Sedan VQ35DE models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan \u0026amp; Infiniti Performance Standard\u003c\/h3\u003e\n\u003cp\u003eThe VQ-series engine is world-renowned for its throttle response and distinct exhaust note.
