Downpipes for Mercedes-Benz W205 C63 / C63S (M177 4.0L Twin-Turbo V8)

These downpipes are engineered with performance as the top priority. Each unit is wrapped in high-temperature shielding to retain heat within the exhaust system and minimize engine bay temperatures. The result is a cooler-running engine that delivers sharper throttle response and faster turbo spool.

Developed with advanced CAD design for an exact OEM fit, these downpipes directly replace the restrictive factory catalytic converters. They’re precision cast from T304 stainless steel, then hand TIG-welded and back-purged for maximum strength and long-term reliability.

The upgrade also enhances the exhaust note—deeper, louder, and more aggressive, without losing refinement.

Key Features:

- Direct bolt-on installation
- Premium T304 stainless steel construction with integrated heat shielding
- TIG-welded and back-purged for durability
- Noticeable gains in power and responsiveness
- Distinctive, more resonant exhaust tone
- Retains factory mounting points

PLEASE NOTE- THIS IS NOT A 100% FIT WILL NEED MINOR MODIFACTIONS TO WORK
