Description
The Milltek Large Bore Downpipe with Hi-Flow Sports Catalyst is designed to significantly enhance the performance of the Mercedes W205 C63 and C63S models with the 4.0 Bi-Turbo V8 engine. OEM catalysts are often restrictive, limiting gas flow and overall engine performance. The Milltek Hi-Flow Sports Catalyst, paired with a large-bore downpipe, helps improve gas flow, allowing your engine to breathe more freely and unlock additional power.
This downpipe and sports catalyst combination replaces both the primary and secondary catalysts of the OE system, reducing restrictions and optimizing the exhaust flow. This upgrade allows for a more aggressive sound and improved power output, making it the ideal choice for those looking to enhance their vehicle's performance.
As with all performance upgrades, this system requires a Stage 2 ECU remap to fully realize the benefits of the increased exhaust flow.
