Mercedes-AMG S63 Stainless Steel Downpipes

These 4"-to-3" downpipes for the Mercedes-AMG S63 4.0L V8 feature a CNC-machined stainless steel V-band-to-pipe transition. A full 3D design right up to the turbo improves flow, with gains of around 50 HP and 60 lb-ft when tuned, and heat shielding helps keep engine bay temperatures down. Handcrafted from corrosion-resistant 304 stainless steel.

Features

• Major increases in power throughout the powerband (with tune)

• Exotic exhaust note
• Precise fitment using factory heat shielding
