Best AMG E63 (W213) Exhaust Systems: 2018-2023 Guide

Choosing an AMG E63 W213 exhaust is the single most impactful mod you can bolt to Mercedes-AMG's hand-built 4.0L twin-turbo V8. The W213-generation E63 and E63 S (2018-2023) make 603 hp and 627 lb-ft from the M177 engine, yet the factory particulate-filter exhaust muffles most of that fury. A proper titanium or valved stainless cat-back frees the sound, trims meaningful weight over the rear axle, and — on some systems — recovers usable power. At NLP Performance in Tampa, FL, the E63 exhaust question comes up constantly, so we pulled our top five W213 systems together with real specs, weights, and pricing to help you choose.

Why upgrade the E63 W213 exhaust?

The W213 E63 leaves the factory strangled by emissions hardware. Mercedes-AMG's M177 is a 4.0-liter biturbo V8 built one-engine-one-builder in Affalterbach, rated at 603 hp and 627 lb-ft in E63 S trim (563 hp on the base E63 sold outside the US). It routes power through a 9-speed AMG Speedshift MCT transmission and 4Matic+ all-wheel drive, launching to 60 mph in about 3.3 seconds. The catch: gasoline particulate filters and heavy factory mufflers blunt the exhaust note and add dead weight behind the rear axle, exactly where you least want it for handling.

A performance exhaust addresses three things at once. First, sound — unlocking the hot-V V8's crackle, overrun pops, and top-end wail. Second, weight — a titanium system like the Akrapovic Evolution Line strips up to 45% of the OEM exhaust mass, and even the stainless AWE SwitchPath saves 17 lb. Third, flow — larger-diameter, mandrel-bent piping and valved mufflers reduce backpressure, which is how the AWE system recovers up to 35 hp and 53 lb-ft at the crank. Because the M177 is already turbocharged, exhaust gains are real but modest; the headline benefits are sound and weight.

Best AMG E63 W213 exhaust systems compared

Here are the five W213 E63 exhaust options we stock, from the full titanium Akrapovic flagship to individual Akrapovic components you can build up over time. Every product name and price below links straight to the product page.

1. Akrapovic Evolution Line (Titanium) — best overall

The Akrapovic Evolution Line is the benchmark full titanium exhaust for the E63 W213. This complete configuration pairs the titanium cat-back with the titanium link pipes and hand-crafted high-gloss carbon-fiber tailpipes, so it is everything you need in one box for around $11,200. Akrapovic forms the entire system from specially developed ultra-lightweight titanium alloys and casts key parts in its own foundry, including an active X connection and an extra pair of exhaust valves behind the rear mufflers for precise sound control.

2. AWE Tuning SwitchPath — best value with power gains

If you want switchable volume and verified dyno gains without spending five figures, the AWE Tuning SwitchPath is the smart buy in the low $4,300 range. AWE hand-builds it from dual 3-inch, .065-inch-wall US-sourced CNC mandrel-bent T304L stainless steel, with a valved H-pipe up front and valved resonators in the rear. Press the button and the exhaust switches from a quiet, resonance-free cruise to full attack. AWE measured peak gains of 23 hp and 7 lb-ft, with max gains of 35 hp at 6,300 rpm and 53 lb-ft at 3,000 rpm at the crank, plus 17 lb of weight savings over stock.

3. Akrapovic Evolution Line Cat-Back (no tips)

Already own carbon-fiber tips, or plan to reuse a factory tip look? The Akrapovic Evolution Line Cat-Back without tips is the same titanium system as our top pick, minus the tailpipes, for around $6,200. You keep the full titanium construction, active valve control, and the active X connection — then finish it with the tip set of your choice.

4. Akrapovic Evolution Link Pipe Set (Titanium)

The Evolution Link Pipe Set is the titanium mid-pipe that ties the Akrapovic cat-back to the factory downpipes, and it is where a lot of the added volume and rasp comes from. At around $3,200 it is the way to sharpen the note without buying a full system in one go, and it fits both the S213 wagon and W213 sedan E63 S.

5. Akrapovic Evolution Tail Pipe Set (High-Gloss Carbon)

The finishing touch: Akrapovic's high-gloss carbon-fiber tailpipe set. These hand-crafted tips complete the Evolution Line look for around $1,840 and shave a few more grams versus metal tips. They are the natural pairing for the no-tips cat-back above if you want the show-quality gloss weave out back.

Titanium vs stainless: which E63 exhaust material?

Titanium is the premium choice for the E63 W213 because it is dramatically lighter — Akrapovic's titanium Evolution Line strips up to 45% of the OEM exhaust weight, all of it behind the rear axle where it most affects handling and rotational balance. Titanium also tolerates the M177's high exhaust temperatures beautifully and develops a distinctive blued patina at the tips. The trade-off is cost: a full titanium system runs into five figures.

T304L stainless steel, like AWE uses in the SwitchPath, is heavier but far more affordable and every bit as durable for street and track use. Because AWE's system is valved, you get switchable volume that titanium fixed-valve systems match only through the car's drive modes. For most E63 owners who want gains, switchable sound, and a sane price, stainless is the pragmatic answer; for the lightest possible build and the exotic look, titanium wins.

DPE vs non-DPE and installation notes

Before you buy the AWE SwitchPath, confirm whether your E63 came with the AMG Performance Exhaust. AWE builds two versions: the DPE (Dynamic Performance Exhaust) version we stock uses your factory valve controls, so you keep the OEM exhaust button; the non-DPE version adds its own valve control for cars without the factory system. Ordering the wrong one is the most common mistake, so check your window sticker or ask our Tampa team if you are unsure.

Installation of any of these cat-back systems is bolt-on and typically takes an experienced technician two to three hours on a lift. The Akrapovic Evolution Line is genuinely plug-and-play and needs no ECU remap. None of these systems require tuning to function, though pairing an exhaust with an ECU tune is where the M177 really wakes up. As always, an aftermarket exhaust can affect emissions compliance depending on your state; these are sold for the intended fitment shown.
