This OEM configuration introduces significant backpressure, which chokes the naturally aspirated VQ37VHR engine at higher RPMs. Furthermore, the restrictive Y-pipe and mid-pipe transitions create exhaust turbulence, generating heat soak and limiting both low-end torque and high-end horsepower production during aggressive driving scenarios.\u003c\/p\u003e\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis catback system resolves factory flow limitations by utilizing 2.25-inch major piping constructed from premium T-304 stainless steel. Computerized mandrel bending ensures a consistent internal diameter throughout the exhaust path, eliminating pinch points and maintaining maximum exhaust gas velocity. By optimizing the cylinder scavenging effect, this system yields a dyno-proven output increase of 15 to 25 horsepower and vastly improved low-end torque. The CNC-machined, TIG-welded flanges resist warping under severe thermal stress and high pressures, ensuring a leak-free seal. The system terminates in dual 4.00-inch slanted and burnt exhaust tips that enhance the rear aesthetics while delivering a deep, aggressive resonance. Gaskets and hardware are included for a direct bolt-on installation.\u003c\/p\u003e\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;\"\u003e2009-2020 Nissan 370Z\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\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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2009-2020 Nissan 370Z Base 3.7L V6\u003c\/li\u003e\n\u003cli\u003e2009-2020 Nissan 370Z Touring 3.7L V6\u003c\/li\u003e\n\u003cli\u003e2009-2020 Nissan 370Z Sport 3.7L V6\u003c\/li\u003e\n\u003cli\u003e2009-2020 Nissan 370Z Nismo 3.7L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Nissan Caliber\u003c\/h3\u003e\n\u003cp\u003eDesigned to maximize the naturally aspirated power of the VQ platform, this exhaust eliminates restriction to deliver the uninhibited high-RPM horsepower and aggressive V6 resonance expected from a dedicated JDM track chassis.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48293031936248,"sku":"DS-EU7DA6DNA","price":399.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-muffler-catback-for-nissan-370z-2009-2020-1.webp?v=1777405370","url":"https:\/\/performancechiptuning.com\/fr\/products\/exhaust-muffler-catback-for-nissan-370z-2009-2020","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
