This restriction traps heat and limits the exhaust scavenging your inline-six needs to perform at its best.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Engineering Solution:\u003c\/strong\u003e Our 6-1 piping design uses precision-bent 1.50\" x 1.25\" primary tubes to streamline exhaust gas velocity. Constructed with CNC-machined 7\/16\" head flanges and high-strength TIG\/MIG welds, this header ensures a flat, leak-free seal. The 3-stage polished finish provides a clean look under the hood while replacing brittle OEM components with durable stainless steel.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eThe Comparative Edge\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerformance Scavenging:\u003c\/strong\u003e 6-into-1 collector design improves torque and throttle response compared to stock logs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Build:\u003c\/strong\u003e Features a thick 7\/16\" head flange and 3\/8\" outlet flange to resist warping under high temperatures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Replacement:\u003c\/strong\u003e Direct replacement for OEM part numbers 17100-61082 and 17111-61020.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfessional Finish:\u003c\/strong\u003e 3-stage polish for superior corrosion resistance and engine bay aesthetics.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 10px;\"\u003eFitment\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003e1969-1987 Toyota Land Cruiser (FJ40\/45\/55\/60)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px;\"\u003eEngine\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003e4.2L Inline 6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 10px;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003e17100-61082, 17111-61020\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px;\"\u003ePiping Design\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003e6-1 Header\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 10px;\"\u003eOutlet Size\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003e2.50\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px;\"\u003ePrimary Tube Size\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003e1.50\" x 1.25\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1969-1987 Toyota Land Cruiser FJ40\u003c\/li\u003e\n\u003cli\u003e1969-1987 Toyota Land Cruiser FJ45\u003c\/li\u003e\n\u003cli\u003e1969-1987 Toyota Land Cruiser FJ55\u003c\/li\u003e\n\u003cli\u003e1980-1987 Toyota Land Cruiser FJ60\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eNote: This header uses factory studs.
