Downpipe is designed to:
Audi S4 S5 B9 3.0 TFSI
Inlet diameter: Outlet diameter: Double-layer heatshielding is used to protect surrounding parts, wires, and hoses against radiant heat from the downpipes.
Integrated thermal insulation reduces surface temperature up to 70%! What makes it an absolute winner, compared to usual thermal wrapping or ceramic coatings.
