Muffler flex hose specification

Tags: #exhaust · #heat-shield · #part-number

Facelift muffler flex-hose size. For the FAW X80 facelift, the muffler's flexible hose (gofra) specification is 55×120 mm (diameter × length). Recommendation: physically measure the existing hose before ordering, and buy slightly extra length beyond the bare minimum to give installation margin/safety.¹²³

Muffler heat shield — part numbers and DIY alternative. A related but distinct exhaust-thermal component: the muffler assembly's heat shield/thermal screen consists of multiple panels with part numbers 5CA05615A and 5CA05615B (insulation panels) plus 5CA056444 (central heat panel). If official parts aren't available, a DIY alternative reported by owners is thermal-insulation material such as StP Hard Shell (sold in 0.5×0.5 m sheets), cut and shaped to substitute for the OEM panels.⁴⁵⁶⁷
