Redstar Downpipes for Mercedes S63 C217 / A217 / W222

Redstar Exhaust Performance S63 Downpipes are the best way to get that noted V8 exhaust tone with burbles & crackles from your 5.5L M157 biturbo AMG engine. We added an X-pipe that helped to balance exhaust tone for this luxury Mercedes model.

• Double-layer heat shielding- 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. It's very important not just for safety reasons but also affects engine performance by reducing the underhood temperature. We highly recommend this option, especially for catted downpipes.
• Straight Tunable 02 Spacers - Comes with 3 inserts to restrict flow to the 02 sensor and help set ready and prevent Engine Light conditions when using the Competition model without proper tuning.
