3" Stainless Steel Downpipe w/ Catalytic Converters

CTS Turbo offers these 3" High-Flow Downpipes specifically for the Mercedes-Benz W205 C63/63S models equipped with the M177 engine. Engineered with performance as the primary goal, these downpipes aim to improve spool and throttle response. They are constructed from durable, hand-crafted T304 stainless steel tubing, featuring TIG welded and back-purged seams for longevity. The design incorporates OE-style heatshielding to effectively manage exhaust heat, allowing for harder and longer driving without concerns about excessive engine bay temperatures. The system utilizes OEM mounting points for a precise fit. In addition to performance gains, these downpipes also enhance the exhaust note, providing a deeper and louder tone. Fitment is confirmed for the 2015-2021 Mercedes-Benz C63 and C63S models. It is important to note that downpipe-specific tuning (Stage 2) is required to prevent a Check Engine Light (CEL). These downpipes are sold for competition use only and are not legal for use in highway or street vehicles. Users should be aware that this product is intended for off-road applications and may not comply with emissions regulations in their region.
