Pure Titanium Power Meets German Engineering Authority on the G63 AMG
The Akrapovic S-ME/TI/5/1 Evolution Line Exhaust System in Titanium is the definitive full-system exhaust upgrade for the 2019 to 2024 Mercedes-Benz G63 AMG (W463A) with the 4.0L V8 biturbo engine. Engineered and handcrafted in Slovenia, this catback system replaces the stock exhaust entirely from the headers to the tips, delivering verified dyno-tested gains of 12 kW (16 HP) at 5,050 rpm and 17 Nm of torque at 4,300 rpm while shedding a remarkable 24.7 kg compared to the factory system. Akrapovic S-ME/TI/5/1 transforms the G-Class driving character through premium aerospace-grade titanium construction and INCONEL heat shielding, producing a deep, authoritative exhaust note that commands attention without cabin drone.
Key Features
- Verified Dyno Power Gains — The Akrapovic S-ME/TI/5/1 delivers a confirmed 12 kW (16 HP) gain at 5,050 rpm and 17 Nm of torque at 4,300 rpm on a stock 2019 Mercedes-Benz G63 AMG W463A test vehicle.
- Massive Weight Reduction — The complete system weighs just 13.8 kg versus the OE system at 38.5 kg, saving 24.7 kg for measurably improved acceleration, braking, and agility.
- Aerospace-Grade Titanium Shell — Over 80 percent of the system is Grade 1 and Grade 2 titanium. INCONEL alloy headers handle extreme turbine-exit temperatures without warping or cracking.
- Race-Tuned Sound Engineering — Integrated resonance chambers within the link pipe assembly produce a deep, aggressive idle and full-throttle roar without the drone that plagues aftermarket exhausts at highway cruise.
- Direct Bolt-On Fitment — Designed specifically for the G63 AMG W463A 4.0L V8 biturbo platform. No cutting, welding, or modification required. All OE mounting points align perfectly.
- Handcrafted in Slovenia — Each Akrapovic S-ME/TI/5/1 is assembled by skilled technicians at the Akrapovic factory using precision TIG welding and multi-stage quality inspection.
- Lifetime Manufacturing Warranty — Covered by Akrapovic's lifetime warranty against defects in materials and workmanship.

Frequently Asked Questions
Does the Akrapovic S-ME/TI/5/1 fit the 2019-2024 Mercedes-Benz G63 AMG W463A without modification?Yes. The Akrapovic S-ME/TI/5/1 is engineered as a direct bolt-on replacement for the 2019 to 2024 G63 AMG W463A. It uses the factory mounting points and requires no cutting, welding, or modification to the vehicle.
What horsepower gains does the Akrapovic S-ME/TI/5/1 provide on the G63 AMG?Akrapovic's own dyno testing on a stock 2019 G63 AMG W463A documented a gain of 12 kW (approximately 16 HP) at 5,050 rpm and 17 Nm of torque at 4,300 rpm when the S-ME/TI/5/1 Evolution Line system is fitted.
Does the Akrapovic G63 AMG Evolution Line catback require an ECU tune?No tune is required to install and run the Akrapovic S-ME/TI/5/1. The system produces measured gains on its own. An optional ECU remap can complement the exhaust to extract additional performance, but it is not a prerequisite.
Is the S-ME/TI/5/1 compatible with G63 AMG models that have OPF or GPF filters?No. The Akrapovic S-ME/TI/5/1 is designed for G63 AMG W463A vehicles without OPF or GPF particulate filters. For OPF/GPF-equipped models, see the Akrapovic S-ME/TI/4/1 variant.
How much weight does the Akrapovic titanium catback save over the stock G63 AMG exhaust?The Akrapovic S-ME/TI/5/1 weighs 13.8 kg. The factory exhaust system on the G63 AMG W463A weighs 38.5 kg. That is a reduction of 24.7 kg, which meaningfully improves the vehicle's power-to-weight ratio and dynamic response.
What does the Akrapovic G63 AMG Evolution Line exhaust sound like?At idle and low throttle the system produces a deeper, more authoritative tone compared to the OE exhaust. Under hard acceleration the sound opens into a full race-inspired V8 roar. The integrated resonance chambers in the link pipes prevent the drone that afflicts many straight-piped systems at highway speeds.
Does the Akrapovic S-ME/TI/5/1 include exhaust tips?Yes. The Evolution Line system ships with a complete set of titanium exhaust tips as part of the kit. No separate tip purchase is needed.
What warranty covers the Akrapovic G63 AMG Evolution Line exhaust?Akrapovic provides a lifetime warranty on the S-ME/TI/5/1 against defects in materials and workmanship. This covers the titanium construction and all welded joints under normal performance driving use.
How long does installation take on the G63 AMG?An experienced shop typically completes the Akrapovic S-ME/TI/5/1 installation in three to five hours on a lift. The system uses all factory mounting hardware locations. Professional installation is recommended to ensure proper torque and fitment.
Installation Instructions
- Raise the vehicle safely on a lift and allow the stock exhaust to cool completely before handling.
- Spray all OE exhaust fasteners and hangers with penetrating lubricant and allow to soak for 15 minutes.
- Remove the OE exhaust tips, muffler assembly, mid-pipe, and header system from rear to front.
- Clean all flange surfaces and mounting points. Inspect rubber hanger brackets and replace any that are cracked or deformed.
- Install the Akrapovic INCONEL header assembly first, torquing flange bolts to the specification in the included instructions.
- Connect the titanium link pipe set with resonance chamber, securing all clamps hand-tight.
- Hang the titanium muffler assembly using the supplied mounting hardware. Do not fully tighten yet.
- Align all components for clearance from the underfloor, heat shields, and driveshaft. Confirm symmetrical tip position.
- Torque all clamps and fasteners to the specification provided in the Akrapovic instruction sheet.
- Start the engine and check for exhaust leaks at all joints. Let the system heat cycle twice before performing a final visual inspection.
