2015-2017 AMG C63 W205 Akrapovic Exhaust Install Guide

The Akrapovic Evolution Line is the definitive titanium exhaust upgrade for the 2015–2017 Mercedes-AMG C63 (W205), and this guide covers exactly how it installs, what it fits, and why it transforms the M177 4.0-liter biturbo V8. From the factory, the C63 makes 469 hp and 479 lb-ft while the C63 S climbs to 503 hp and 516 lb-ft — yet both cars leave the plant with a heavy steel exhaust that muffles the V8 until you dig deep into the drive modes. Swapping to Akrapovic’s hand-built titanium system cuts more than 45% of exhaust weight, adds cabin-controlled valves, and finishes the diffuser with hand-crafted matte carbon-fiber tips. At NLP Performance in Tampa, FL, this is one of the most requested W205 upgrades we ship.

Why Upgrade the C63 W205 Exhaust?

Upgrading the C63 W205 exhaust is about weight, sound, and response — not chasing a big dyno number. The M177 is a twin-turbocharged 4.0-liter “hot-vee” V8 with the turbos nested inside the valley, and on a forced-induction engine the mufflers matter more for backpressure, tone, and mass than for peak horsepower. Expect single-digit horsepower gains from a bolt-on cat-back; the real transformation is a lighter tail end and a V8 voice that finally matches the car’s 469–503 hp output.

The factory C63 and C63 S drive their power through a 7-speed AMG SPEEDSHIFT MCT wet-clutch transmission to the rear wheels, hitting 60 mph in roughly 4.0 and 3.9 seconds respectively. The stock exhaust is a big contributor to unsprung and rear-biased weight, so shedding it with titanium sharpens throttle response and rotation. Akrapovic’s Evolution Line is built from specially developed lightweight titanium alloys and reduces exhaust weight by more than 45% versus the OE steel system — a meaningful figure on a car this rear-heavy.

The Akrapovic Evolution Line System, Explained

The Evolution Line is a complete titanium cat-back system that replaces everything behind the OE catalytic converters. It uses an active X-connection and an additional pair of exhaust valves mounted behind the rear mufflers, giving two defined sound characteristics across three driving sound settings. The cat-back is ECE type-approved and requires no ECU remap, but it is a two-part purchase: the muffler system plus the matching Evolution link pipe set that ties it into the factory downpipes.

C63 W205 Akrapovic Exhaust Parts Compared

Here is how the four pieces of the Akrapovic C63 W205 exhaust puzzle fit together. Pick the cat-back that matches your body style, add the required link pipe set, and choose whether you want the optional Sound Kit controller for full-time tone control.

What You Need Before You Start

A C63 Akrapovic install is a straightforward bolt-on for an equipped DIYer or independent shop — budget 2 to 4 hours on a two-post lift. Because the Evolution Line reuses the factory hangers and valve actuators, there is no cutting, welding, or tuning involved. Gather your parts and tools first so the car is not stranded on the lift.

Parts: the correct Evolution Line cat-back for your body style, the Evolution link pipe set, and (optionally) the Sound Kit controller. Tools: a full metric socket and wrench set, penetrating oil for the factory clamp hardware, exhaust hanger removal pliers or spray lube, a torque wrench, plastic trim tools if you are wiring the sound controller, and a second set of hands to support the mufflers.

Step-by-Step Akrapovic C63 Exhaust Installation

Follow these steps to install the Akrapovic Evolution Line on your C63 W205. Always work on a cold exhaust and confirm torque values against the printed Akrapovic instructions, which ship with the system.

1. Prep and lift. Let the exhaust cool completely, raise the car level on a lift or jack stands, and disconnect the battery if you plan to wire the Sound Kit controller.
2. Unplug the OE valves. Locate and disconnect the factory exhaust-valve actuator connectors at the rear mufflers so the harness stays intact for the Akrapovic valves.
3. Support and remove the stock system. Sling or brace the OE mufflers, then loosen the clamps at the link-pipe junction and slide the factory cat-back off its rubber hangers.
4. Install the Evolution link pipes. Bolt the titanium link pipe set to the factory downpipe outlets, leaving the clamps hand-tight so the system can still be aligned.
5. Hang the Akrapovic cat-back. Slip the titanium mufflers onto the link pipes and seat them on the OE hangers, again keeping hardware loose for final adjustment.
6. Reconnect the valves. Plug the factory actuator connectors into the Akrapovic exhaust valves and route the wiring clear of heat and moving parts.
7. Align the carbon tips. Center the matte carbon-fiber tailpipes in the diffuser cutouts, matching height and depth on both sides before tightening.
8. Torque everything down. Working front to back, tighten the band clamps and hanger hardware to spec (exhaust band clamps are typically around 20–25 Nm; verify with the supplied instructions).
9. Optional: fit the Sound Kit. Install the P-HF949 controller per its instructions for full-time cabin tone control, then reconnect the battery.
10. Start and verify. Fire the engine, check every joint for leaks, cycle the drive modes to confirm valve operation, then re-check tip alignment after one heat cycle.

Sound, Valve Control, and Drive Modes

The Akrapovic Evolution Line gives the C63 W205 an aggressive, layered V8 voice with an added pair of valves for on-demand control. Because the valves sit behind the rear mufflers and tie into the factory harness, they respond to the car’s existing drive modes — quiet and civil in Comfort, hard-edged and open in Sport+ and Race. Akrapovic tunes the system with two defined sound characteristics and three driving sound settings so you get a usable daily-driver mode as well as a track roar.

For owners who want the valves open regardless of drive mode, the optional Sound Kit controller (P-HF949) overrides the factory logic so you can run the loud setting even in Comfort. It is the single best pairing with the cat-back if you bought the C63 for its soundtrack.

Fitment and Compatibility

The correct Akrapovic part depends on your C63 W205 body style, and every cat-back requires the matching link pipe set. Sedan (W205) and estate (S205) owners use the MTP-ME/T/2H/1 system, while coupe (C205) owners use the MTP-ME/T/3H. Both the standard C63 and the C63 S share the same M177 4.0-liter V8 and the same exhaust fitment, so either output level bolts up to the same system.

Planning a full W205 build? The exhaust pairs naturally with a proper coilover setup like the KW V4 coilover kit for the C63 W205, and you can browse the rest of our catalog in the exhaust collection and suspension collection. If you are unsure which link pipe or cat-back matches your exact car, our Tampa team will confirm the part before you order.
