Mercedes-AMG C63 W205 Akrapovic Exhaust Buyer's Guide

If you own a 2015–2018 Mercedes-AMG C63 (W205), the single most transformative bolt-on you can fit is an Akrapovic Evolution Line titanium exhaust. Mercedes gave the C63 and C63 S one of the greatest engines it has ever built — the AMG M177 4.0-liter biturbo V8, rated at 469 hp / 479 lb-ft in the C63 and 503 hp / 516 lb-ft in the C63 S — then muffled it with a heavy, restrictive factory exhaust. This guide breaks down the complete Akrapovic Evolution Line system for the W205 platform: the cat-back for each body style, the required link pipes, and valve control, with real weights, specs, part numbers, and pricing so you can build the system correctly the first time.

Why the W205 C63 Needs the Akrapovic Evolution Line

The factory C63 exhaust is a steel, twin-valve system built for emissions and drive-by noise limits, not for weight or sound. The Akrapovic Evolution Line replaces both the base and performance factory exhausts with a full titanium system that weighs about 13 kg (roughly 29 lb) less — a weight savings in excess of 45%. On a car that already carries its mass high and forward over the front axle, stripping meaningful weight off the rear underbody sharpens throttle response and helps rotation, while the free-flowing titanium mufflers finally let the M177 breathe.

Akrapovic quotes measurable gains on the dyno as well: roughly +5.9 kW (about 8 hp) at 2,000 rpm and +27.9 Nm (about 21 lb-ft) at 1,850 rpm. These are low-end, in-the-powerband figures — exactly where a heavy sedan or wagon lives in daily driving — not peak-only marketing numbers. Combined with the sound, the Evolution Line makes the C63 feel noticeably more urgent everywhere in the rev range.

What Makes the Evolution Line Different?

The Evolution Line is Akrapovic's flagship, motorsport-derived system — a step above the Slip-On Line. It is built from ultra-lightweight titanium alloys developed in-house, with parts cast in Akrapovic's own foundry, and finished with hand-crafted matte carbon-fiber tailpipes. The system uses an active X connection and an additional pair of exhaust valves behind the rear mufflers, giving two defined sound characteristics across three driving sound settings. It is ECE type-approved and requires no ECU remap — a true plug-and-play upgrade. Note: it is designed for W205 cars without an Otto particulate filter (OPF), and this configuration is sold for off-road/track use (not CARB-approved; no shipping to California).

Evolution Line Cat-Back — Sedan & Estate (W205 / S205)

This is the cat-back for the four-door C63/C63 S sedan and the C63 Estate wagon. It carries Akrapovic part number MTP-ME/T/2H/1 and, like every Evolution Line cat-back for this car, requires the separate Evolution Link Pipe Set to bolt up. It is our overall top pick for the W205 — the biggest weight loss, the fullest V8 sound, and the widest fitment.

Evolution Line Cat-Back — Coupe (C205)

The two-door C63/C63 S Coupe uses its own dedicated cat-back, part number MTP-ME/T/3H. It shares the Evolution Line's titanium construction, carbon tips, and valve-controlled sound, and like the sedan/estate system it also requires the Evolution Link Pipe Set. Fitment is 2016–2017 C63 AMG Coupe.

Why You Need the Evolution Link Pipe Set

The Evolution Line cat-back does not bolt directly to the factory downpipes — it needs the titanium Evolution Link Pipe Set (part E-ME/T/3) to connect. The link pipes replace the restrictive secondary catalytic converters, which is where much of the flow and sound improvement actually comes from. Both part numbers must be ordered together to build a complete, functioning system. Skipping the link pipes is the single most common mistake C63 owners make when buying an Akrapovic system, so budget for both from the start.

Sound & Valve Control: Getting the Most From the M177

The Evolution Line's active valves give the C63 a Jekyll-and-Hyde character: quiet enough for a cold-start commute, then a full-blooded biturbo V8 bark in Sport+ with the valves open. If you are deleting the base exhaust or want independent control of the factory valve actuators, a set of electronic valve simulators keeps the car's control module happy and prevents a check-engine light. The AWE Tuning Electronic Valve Simulators are an inexpensive insurance policy for any valved-exhaust build and ship two per unit.

Here is how the pieces of the W205 C63 exhaust system stack up. Pick the cat-back that matches your body style, add the link pipe set (required), and finish with valve control if your build calls for it.

How to Build the Complete System

Building the correct Akrapovic Evolution Line setup for a W205 C63 comes down to three steps. First, choose the cat-back for your body style — MTP-ME/T/2H/1 for the sedan and estate, or MTP-ME/T/3H for the coupe. Second, add the Evolution Link Pipe Set (E-ME/T/3); it is mandatory, not optional. Third, if you are replacing the base (non-performance) factory exhaust or want standalone valve control, add valve simulators so the car does not throw a fault. Installation is a bolt-on job for an experienced shop and needs no tune; in our Tampa, FL shop a full Evolution Line fitment is typically a single-day job. Our customers consistently report the biggest change is character, not just volume — the M177 finally sounds as serious as it drives.
