Is this Akrapovic G 63 4x4 Squared exhaust street legal?

No. Akrapovic states this Evolution Line system does not meet emission compliance requirements for street or highway use in any market. It is built for closed-course and off-road use only, so confirm your local regulations before installing it on a vehicle you plan to drive on public roads.

How much power and torque does this exhaust add to the G 63 4x4 Squared?

Independent testing shows a gain of 8.1 kW (11 hp) at 4,500 rpm and 19 Nm (14 lb-ft) of torque at 4,000 rpm over the factory system. Akrapovic notes that power and torque increase across the entire rpm range, not just at the peak gain points.

How much weight does the Evolution Line save over the factory exhaust on the G 63 4x4 Squared?

The titanium system weighs 12.36 kg (27.3 lb) against the heavier factory steel exhaust, a reduction of 9.9 kg (21.8 lb), or 44.5%. That weight comes off the rear of the vehicle, improving balance on a platform that already carries significant portal-axle hardware.

Do I need to buy the Akrapovic Sound Kit separately for this exhaust?

No. Unlike some Akrapovic Evolution Line systems, the Sound Kit that lets you adjust exhaust tone wirelessly through the Akrapovic app or remote controller is already included with this G 63 4x4 Squared system, so there's no separate electronics purchase required to use it.

Is the front link pipe set required to install this exhaust?

No, it's optional. The Evolution Line system installs and functions on its own; the front link pipe set is offered separately for owners who want additional exhaust-tuning capability beyond what the standard system provides, not as a requirement to complete the install.

Does this exhaust fit the standard G 63, or only the 4x4 Squared version?

This system is built specifically for the Mercedes-AMG G 63 4x4 Squared (W463A), the portal-axle variant with raised suspension, larger tires, and unique bodywork versus the standard model. Akrapovic catalogs it separately from the regular G 63 (W463A), so confirm your exact model and chassis before ordering to avoid a fitment mismatch.

Description

Akrapovic Titanium Evolution Line for W463A Mercedes-AMG G63 4×4 Squared

Name: Akrapovic G63 4x4 Squared Exhaust | Bulletproof Automotive
Brand: Akrapovic
SKU: S-ME/T/2
Price: 12118.25 USD
Availability: InStock

This Akrapovic G63 4×4 Squared exhaust replaces the factory system on the portal-axle Mercedes-AMG G-Class with a full titanium Evolution Line built for a serious sound and measurable power gains, without adding weight to a vehicle that already carries plenty of hardware underneath. Akrapovic builds this system from high-grade titanium finished with tailpipes shaped in its own foundry, routed to clear the 4×4 Squared’s raised suspension and portal axles while cutting 9.9 kg (21.8 lb), or 44.5%, from the stock exhaust’s weight. It’s a system built for owners who want their G63 4×4 Squared to sound as aggressive as it looks, on closed courses and off-road terrain.

Sound and Valve Control

A pair of exhaust valves behind the rear mufflers gives this system a deeper, sportier tone that’s especially pronounced under acceleration and through gear changes, with power and torque gains carrying across the entire rpm range rather than a single peak. The Akrapovic Sound Kit, which lets you switch between regular and sport modes wirelessly from the Akrapovic app or a remote controller, comes included with this system rather than sold as a separate add-on.

Features

Full titanium construction for reduced weight and a deeper, more resonant exhaust note
Foundry-shaped titanium tailpipes exiting on either side of the vehicle
Dual exhaust valves for adjustable sound control
Akrapovic Sound Kit included for wireless mode switching via app or remote
Optional front link pipe set available separately for additional exhaust-tuning capability

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
