Akrapovic 20-21 Porsche 911 Turbo/Turbo S (992) Tail Pipe Set (Titanium) - BlackTP T S 33 As the most visible part of an exhaust system, we pay the utmost attention to the tailpipes. There is a choice between two different sets of round titanium tailpipes, sandblasted and coated, and available in a natural titanium finish or black. The inner side of the tailpipes features a dynamic relief surface for increased aesthetic value.
