Does the Capristo Valved Exhaust fit both the GL 63 and the GLS 63?

Yes. This system fits the X166 Mercedes-AMG GL 63 (2013-2015) and the facelifted GLS 63 (2015-2019), both running the 5.5-liter twin-turbo V8. It is specific to the X166 platform and is not designed for the later W167/X167 GLE 63 or GLS 63, which use a different 4.0-liter engine and chassis.

How do the CES-3 valves and driving modes work?

The exhaust valves are controlled by backpressure through the included CES-3 module and key fob. Cruise keeps the valves closed until higher RPM for quiet driving, Sport opens them earlier and under hard acceleration, and Open holds them open at all times. Cruise and Sport can each be tuned to a separate backpressure threshold.

Will this exhaust drone on the highway?

Cruise mode is built for exactly this. It holds the valves closed through normal cruising RPM to keep the cabin quiet on long drives, so you can settle the vehicle down when you want to. Switch to Sport or Open from the key fob when you want the full voice of the 5.5-liter V8.

What is the Capristo Valved Exhaust made from?

The Capristo Valved Exhaust is built from hand-welded T309 (1.4828) stainless steel, an alloy rated beyond 600°C and chosen for the same heat tolerance that makes Inconel a Formula 1 material. Tubing is mandrel-bent to preserve flow and hand-polished, which gives the system its durability and consistent sound over time.

Does it reuse the factory tips, or is cutting required?

It reuses the factory exhaust tips and bolts to the factory mounting points, so the finished look stays OEM-correct. Because it includes the connecting mid-pipes and locates on the original hangers, installation is a direct fitment to the X166 without cutting the vehicle's bodywork.

Is this exhaust street legal in California?

No. This system is not CARB approved and cannot be sold or shipped to California or other states that require CARB certification. It is intended for closed-course or off-road use in jurisdictions that permit it, and no determination has been made regarding EPA anti-tampering compliance.

Description

Capristo Valved Exhaust w/ Mid-Pipes for X166 Mercedes-AMG GL 63 / GLS 63

The esteemed Capristo Valved Exhaust System is recognized for providing a multifaceted auditory experience, proficient in emitting a bold exhaust note during acceleration while maintaining a refined, sophisticated sound for urban driving.

Craftmanship

Employing innovative technologies such as 3D Laser-Scanning, CAD Design, Digital modeling, and CNC precision, each Capristo exhaust system is meticulously sculpted in their renowned German workshop. Each piece is intricately molded from premium T309 (1.4828) Stainless Steel and is diligently hand-polished to exhibit a flawless gleam. Following rigorous assessment, this specific alloy was selected due to its unmatched acoustic purity, advantages in weight mitigation, and enduring resilience—qualities analogous to the Inconel characteristics observed in elite Formula 1 competitions.

CES-3 Control Module

The backpressure-controlled exhaust valves are able to be customized by the user via the included CES-3 Control Module. This programmable control unit comes with three operating modes that can be navigated through a remote key fob.
- Cruise: Exhaust valves open at higher RPMs
- Sport: Exhaust valves open at lower RPMs and hard acceleration
- Open: Exhaust Valves Remain Open
The Cruise and Sport modes in the vehicle can be individually adjusted to set distinct backpressure boundaries, which, in turn, decide the activation instances of the exhaust valves. This grants precise control over the exhaust system, allowing alterations to suit the driver’s unique preferences and endurance.

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.
