Crushed-bent mild steel runs, internal muffler baffles, and heavy active-exhaust valve assemblies create severe post-turbine backpressure on the twin TD04 turbochargers. Over decades of heat cycling, the OEM mild steel piping suffers internal scaling and external rust, leading to structural rot at the hanger welds and exhaust leaks at the slip flanges that hurt scavenging.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis cat-back system replaces the stock layout from the catalytic converter rearward with smooth, mandrel-bent 2.5-inch corrosion-resistant stainless steel piping. Eliminating internal bottlenecks allows the \u003cstrong\u003e6G72TT\u003c\/strong\u003e V6 to evacuate exhaust gases rapidly, lowering exhaust gas temperatures (EGTs) and shortening spool time on both turbochargers. The system features rigid, pre-welded exhaust hangers that match the OEM isolator locations and comes equipped with precision-faced flanges to guarantee a leak-free seal under full boost. It terminates in an aggressive 3-inch quad polished tip configuration that fits neatly within the rear bumper cutouts.\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;\"\u003e1991-1999 Mitsubishi 3000GT VR-4\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\u003e6G72TT\u003c\/strong\u003e \/ \u003cstrong\u003eZ16A\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;\"\u003e300–320 hp \/ 307–315 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;\"\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\u003e1991-1999 Mitsubishi 3000GT VR-4 Turbo AWD\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the Z16A 3000GT?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1991-1999 Mitsubishi 3000GT equipped with the \u003cstrong\u003e6G72TT\u003c\/strong\u003e twin-turbo engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this catback exhaust require ECU recalibration or tuning?\u003c\/strong\u003e\u003cbr\u003e No recalibration is required, as the catback bolts downstream of the catalytic converter and factory oxygen sensors without altering closed-loop fueling.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mitsubishi JDM Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle the demands of modified AWD twin-turbo powertrains, this stainless steel system delivers the pronounced exhaust note and free-flowing velocity needed to support increased boost without cracking under thermal load.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50512354803960,"sku":"DS-EHJD2U8WI","price":525.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catback-exhaust-for-mitsubishi-3000gt-1991-1999-1.jpg?v=1789426106","url":"https:\/\/performancechiptuning.com\/es\/products\/catback-exhaust-for-mitsubishi-3000gt-1991-1999","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
