Redstar's downpipes replace the factory downpipes on the Mercedes S63 Sedan (W222), S63 Coupe (C217) and S63 Cabriolet (A217) with the M157 5.5L biturbo engine, covering 2013-2017 pre-facelift cars including 4MATIC models. Redstar TIG welds and back purges each pipe from 3" tube with a 2.0 mm wall, fits OEM-spec flanges and keeps all of the factory brackets and mounts, so installation is fully bolt-on. Redstar lists the design for both left- and right-hand-drive cars and states faster spool-up, sharper throttle response and lower under-bonnet temperatures over the factory parts.
