Which Mercedes models does the Capristo Valved Exhaust fit?

It fits the Mercedes-AMG GLC 63 and GLC 63 S on the X253 chassis, both with the 4.0L twin-turbo V8. It fits the factory mounting points, so it installs cleanly and keeps the vehicle's OEM fitment at the rear. Confirm your model year against the fitment list before ordering.

How do the valves on the Capristo Valved Exhaust work?

The Capristo Valved Exhaust uses backpressure-controlled valves managed by the included CES-3 control module. A key-fob remote switches between three modes: Cruise opens the valves at higher RPM, Sport opens them earlier and under hard acceleration, and Open keeps them open. Cruise and Sport each have an adjustable backpressure threshold that sets exactly when the valves open.

Does the Capristo Valved Exhaust include mid-pipes and a controller?

Yes. The system includes the valved rear muffler, the mid-pipes and the CES-3 control module with its key-fob remote. It fits the factory mounting points for a direct install at the rear of the GLC, so the valved muffler and mid-pipes carry the sound and flow of the upgrade.

What is the Capristo Valved Exhaust made from?

It is hand-built from T309 (1.4828) stainless steel, a heat-resistant grade chosen for acoustic clarity, light weight and durability. Capristo develops each system with 3D scanning and CNC tooling at its German workshop, then WIG-welds it by hand and polishes it to a high-gloss finish, the same process behind its exotic exhaust systems.

Can I add downpipes to the Capristo Valved Exhaust?

Yes. Capristo makes sport catted downpipes with 250-cell sport cats for the X253 GLC 63, and they pair directly with this valved system for more flow and a stronger note. The downpipes work with the factory exhaust or this Capristo exhaust, so you can add them now or later.

Is the Capristo Valved Exhaust street legal?

It fits the factory mounting points and is street-oriented, but it is not CARB approved and is not legal for sale or use on pollution-controlled vehicles in California or other CARB states. Emissions rules vary by state and country, so check the requirements where you live before buying.

Description

Capristo Valved Exhaust with Mid-Pipes for X253 Mercedes-AMG GLC 63 / S

Capristo Valved Exhaust with Mid-Pipes for the X253 Mercedes-AMG GLC 63 and 63 S gives the 4.0L twin-turbo V8 a voice you control: composed and quiet for daily driving, deep and hard-edged the moment you want it. Built by hand at Capristo’s German workshop from T309 (1.4828) stainless steel, the system runs backpressure-controlled valves managed by the included CES-3 control module, so a key-fob remote switches between Cruise, Sport and Open and sets exactly when the flaps open. It fits the factory mounting points, so the GLC installs cleanly and keeps its OEM fitment while gaining the depth and theater a hand-built valved system brings. For the GLC 63 owner who wants a flagship exhaust with real command of its sound, this is Capristo’s system.

Engineering

Utilizing advanced technologies such as 3D Laser-Scanning, CAD Design, Digital modeling, and CNC precision, each Capristo exhaust system is meticulously built in their esteemed German workshop. Every piece is precisely shaped from refined T309 (1.4828) Stainless Steel and is carefully hand-polished to achieve a flawless shine. This specific alloy was selected after thorough analysis for its exceptional acoustic clarity, lightweight advantages, and enduring robustness—qualities akin to the Inconel features seen in premier 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 car can be customized independently to set specific backpressure limits, which in turn decide when the exhaust valves will activate. This provides precise control over the exhaust system, allowing for adjustments based on the driver’s personal 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.
