CTS Turbo downpipe kit for Mercedes-Benz C63/C63S W205

3-inch downpipe kit with high-flow catalytic converters for the Mercedes-Benz AMG W205 C63/C63S with the M177 engine.

The downpipes are wrapped in protective material that helps retain heat in the exhaust system and direct it away from the engine bay. The result is faster turbocharger spool-up and improved throttle response.

The product was designed using modern CAD technology and is intended to replace the factory catalytic converters with restricted flow. It is made from cast T304 stainless steel, manually TIG-welded and back-purged with shielding gas for long-lasting reliable operation.

The downpipe kit also improves the exhaust sound, making it louder, deeper and more pronounced.
