The diameter never drops below stock at any point in the path, so exhaust gas evacuates faster, spool times shorten, and throttle response sharpens.\u003c\/p\u003e\n\u003cp\u003eA 4.5” Active Aflow Super High Output catalytic converter handles emissions duty, built with full 304 stainless steel construction including the substrate, and carrying a 400 cell per square inch ultra high-flow catalyst. It is EPA registered, compliant in 49 states, fully OBD2 compliant, and will not produce a CEL for catalytic efficiency. The downpipe itself is constructed entirely from 304 stainless steel with 1.5mm wall thickness and TIG-welded throughout, built in Miami, Florida.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNo CEL for catalytic efficiency\u003c\/li\u003e\n\u003cli\u003e4.5” Active Aflow Super High Output catalytic converter, EPA registered and OBD2 compliant in 49 states\u003c\/li\u003e\n\u003cli\u003eFull 304 stainless steel cat construction including the substrate\u003c\/li\u003e\n\u003cli\u003e400 cpsi ultra high-flow substrate\u003c\/li\u003e\n\u003cli\u003eRated for up to 800 HP applications\u003c\/li\u003e\n\u003cli\u003e4.5” mandrel-bent piping tapering to 3.5”, meeting the OEM 80mm connection\u003c\/li\u003e\n\u003cli\u003eNever drops below the stock 80mm diameter\u003c\/li\u003e\n\u003cli\u003eIntegrated stainless flex joint\u003c\/li\u003e\n\u003cli\u003e304 stainless steel with 1.5mm wall thickness, TIG-welded construction\u003c\/li\u003e\n\u003cli\u003eQuicker turbo spool and improved throttle response\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on installation, no cutting or welding\u003c\/li\u003e\n\u003cli\u003eMade in Miami, Florida\u003c\/li\u003e\n\u003cli\u003e5-Year \/ 50,000-Mile Warranty on shell and tube ends, 2-Year \/ 25,000-Mile Warranty on catalytic core\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Fitment\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eToyota GR Supra A90 \/ A91, 3.0L B58 turbocharged inline-six\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerformance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eActive Autowerke measured an increase of 18 whp on their Mustang chassis dyno using this catted downpipe together with the Active Autowerke Signature exhaust on the stock tune.
