CAP M177 Catless Downpipes | 2015-2021 W205 Mercedes-AMG C63/C63S

THE M177 WAS NEVER MEANT TO SOUND THIS QUIET.

Introducing Can Auto Performance's brand new downpipe for the M177 platform. Crafted with the same commitment to excellence as our world-renowned Audi test pipes, the same team has done it again, delivering exceptional quality for the M177 platform with no expense spared.

You bought a C63 for the V8. Then Mercedes buried it behind two catalytic converters bolted right off the turbos. The CAP W205 C63 downpipes pull them out and put straight 304 stainless in their place, so your 2015-2021 C63 or C63S spools harder, pulls sharper, and finally sounds like the car you paid for.

Fits: 2015-2021 Mercedes-AMG C63 and C63S (W205), M177 4.0L twin-turbo V8, North American models.

• Catless, straight 3". Both cats gone. Less backpressure behind each turbine means the boost shows up sooner and the throttle answers faster.
• 304 stainless, 100% TIG welded and back-purged. Clean welds inside the pipe too, right where cheap pipes crack first.
• CNC machined flanges. Flat, true sealing faces at the turbos. No exhaust leaks, no fighting the fit.
• Complete four-piece kit. Driver and passenger downpipes, matching lower pipes, and clamps in the box. Factory mounting points, no cutting, no welding.
• The full hot-vee soundtrack. A cold start that turns heads in the parking lot, louder pulls through every gear, and the crackle the factory cats were eating.

Rated 5.0/5.0 by verified C63 owners.

Fast shipping, lifetime warranty, no duties. Ships from our US or Canadian warehouse and is backed by the CAP Limited Lifetime Warranty. The price at checkout is the price you pay. See our shipping policy and warranty policy.

Plan the tune. The removal of factory catalytic converters will trigger a check engine light. Software tunes are recommended to maximize the power gains.
