Furthermore, the OEM system incorporates severe crush-bent radius turns, internal multi-chambered resonator baffles, and heavy neck-downs that disrupt laminar exhaust velocity. These restrictions create turbulent backpressure behind the \u003cstrong\u003eVQ35DE\u003c\/strong\u003e cylinder heads, dampening exhaust gas scavenging, choking high-RPM volumetric efficiency, and muting the characteristic exhaust note of the 3.5L V6 engine.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from polished stainless steel, this performance cat-back system addresses OEM flow bottlenecks using uniform mandrel-bent piping that maintains internal diameter cross-sections through every sweep. Smooth-radius bends reduce parasitic turbulence, permitting post-catalytic gases to evacuate freely to promote faster turbo-free cylinder emptying during valve overlap. Equipped with low-restriction straight-through mufflers and polished tips, this system withstands thermal fatigue without cracking welds. Pre-welded factory-style hangers and precision mating flanges ensure bolt-on integration using existing underbody mounting points without cutting or chassis modification.\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; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2004-2008 Nissan Maxima\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eVQ35DE\u003c\/strong\u003e \/ \u003cstrong\u003eA34\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e255–265 hp \/ 252–255 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eSPT-CAT1396\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004 Nissan Maxima 3.5L V6 (SE, SL)\u003c\/li\u003e\n  \u003cli\u003e2005 Nissan Maxima 3.5L V6 (SE, SL)\u003c\/li\u003e\n  \u003cli\u003e2006 Nissan Maxima 3.5L V6 (SE, SL)\u003c\/li\u003e\n  \u003cli\u003e2007 Nissan Maxima 3.5L V6 (SE, SL)\u003c\/li\u003e\n  \u003cli\u003e2008 Nissan Maxima 3.5L V6 (SE, SL)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the A34 Maxima?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2004-2008 Nissan Maxima equipped with the \u003cstrong\u003eVQ35DE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this cat-back exhaust trigger a Check Engine Light (CEL)?\u003c\/strong\u003e\u003cbr\u003e No, because this system bolts rearward of the factory catalytic converters, oxygen sensor readings and downstream emissions monitoring remain completely unaffected.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan VQ Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to complement the rev-happy nature of the legendary \u003cstrong\u003eVQ35DE\u003c\/strong\u003e, this exhaust delivers a crisp, resonant tone under load while maintaining durable, leak-free underbody geometry for aggressive daily driving.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50622354587896,"sku":"DS-E4B1ZPV63","price":425.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/cat-back-exhaust-for-nissan-maxima-2004-2008-3-5l-1.jpg?v=1790263489","url":"https:\/\/performancechiptuning.com\/products\/cat-back-exhaust-for-nissan-maxima-2004-2008-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
