These stock silencers create significant exhaust gas recirculation and parasitic backpressure behind the mid-pipe, blunting high-RPM scavenging. Compounding the issue, the OEM units add unnecessary unsprung weight past the rear axle centerline, dulling transient handling response while trapping excessive thermal mass under the rear bumper valence.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis axle-back setup implements a direct straight-through muffler delete fabricated from high-grade polished stainless steel. Featuring 2.50-inch OD mandrel-bent tubing stepping down from a 1.75-inch inlet connection, the design maintains optimal exhaust velocity without turbulence or flow separation. Heavy-duty 3\/8-inch CNC flanges prevent thermal warpage and exhaust leaks under sustained track loads. The assembly terminates in aggressive 4-inch OD double-walled polished exhaust tips, designed to resist heat discoloration and deliver the sharp, uninhibited frequency resonance native to the \u003cstrong\u003eVQ35HR\u003c\/strong\u003e and \u003cstrong\u003eVQ37VHR\u003c\/strong\u003e powerplants.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2007-2013 Infiniti G35, G37 Sedan (4-Door Only)\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;\"\u003eVQ35HR, VQ37VHR \/ V36\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;\"\u003e306-328 hp \/ 268-269 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;\"\u003eAB-IG3507-4D-C\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007-2008 Infiniti G35 Sedan 3.5L V6 (4-Door Sedan)\u003c\/li\u003e\n  \u003cli\u003e2009-2013 Infiniti G37 Sedan 3.7L V6 (4-Door Sedan)\u003c\/li\u003e\n  \u003cli\u003eDoes not fit 2-door Coupe or Convertible models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the V36 G35,G37?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2007-2013 Infiniti G35,G37 equipped with the VQ35HR and VQ37VHR engine.\u003c\/p\u003e\n\n\u003ch4\u003eWill installing this axle-back muffler delete trigger a Check Engine Light (CEL)?\u003c\/h4\u003e\n\u003cp\u003eNo, this system mounts downstream of all catalytic converters and oxygen sensors, maintaining factory emissions monitoring without triggering diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Infiniti Acoustic Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered strictly for competition use, this system strips out dead acoustic weight to let the high-revving VQ engine breathe cleanly, providing instantaneous throttle recovery and a crisp, authoritative exhaust tone under wide-open acceleration.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67530933141752,"sku":"DS-EYZZX25TX","price":253.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/axle-back-exhaust-for-infiniti-g35-g37-sedan-2007-2013-3-5l-3-7l-1.jpg?v=1790525332","url":"https:\/\/performancechiptuning.com\/products\/axle-back-exhaust-for-infiniti-g35-g37-sedan-2007-2013-3-5l-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
