Does the Capristo Valved Exhaust System fit my SL500 or SL550?

Yes. It fits the R231 Mercedes-Benz SL500, which is sold in the United States as the SL550, from 2013 to 2020 with the 4.7 liter biturbo V8. Both names refer to the same car and engine. This is the non-AMG SL; confirm your model and year before ordering so you receive the correct build.

How does the valve system work?

The system uses vacuum-actuated valve flaps that open and close with driving conditions and driver input. At cruise or low rpm the valves stay closed for a quiet, refined tone, and under acceleration they open for a louder, fuller exhaust note. The included CES-3 control module lets you set that behavior from a remote key fob.

What is the CES-3 control module?

It is the programmable valve controller included with the system, operated from a remote key fob. It offers three modes: Cruise opens the valves only at higher rpm, Sport opens them at lower rpm and under hard acceleration, and Open keeps them open. Cruise and Sport can each be set to a chosen back-pressure margin for a custom balance of sound and manners.

What is included with the system?

The system includes the valved rear section and the CES-3 control module with its remote key fob. It uses the factory mounting points, so it installs on the R231 without modified hangers. The system is built for the 4.7 liter biturbo V8 SL500 and SL550; order against your exact model to receive the right fitment.

What is the Capristo Valved Exhaust System made from?

It is made from T309 (1.4828) grade stainless steel, a heat-resistant alloy. Capristo uses mandrel-bent tubing, hand welding, and a hand-polished mirror finish, built at its own German workshop. The grade is chosen to withstand sustained exhaust temperatures while holding its finish over the life of the system.

Is this exhaust street legal?

It is not CARB approved, so it is not legal for sale or use in California or other CARB-compliant states. Emissions and sound rules vary by region, so check your local regulations and your intended use before purchasing. The CES-3 Cruise mode is designed to keep the valves closed for a quieter tone in daily driving.

Description

Capristo Valved Exhaust System for R231 Mercedes-Benz SL500 AMG

The Capristo Valved Exhaust System gives the R231 Mercedes-Benz SL500, sold in the United States as the SL550, two voices in one, hushed and refined at a cruise and full-throated under throttle, through vacuum-actuated valves that Capristo builds by hand in heat-resistant T309 stainless. The flaps stay closed at low load for composed daily manners and open on acceleration to let the 4.7 liter biturbo V8 breathe, trading the muted factory note for genuine presence. The included CES-3 control module puts Cruise, Sport, and Open modes on a remote key fob, and the hand-welded fabrication, mirror-polished finish, and German engineering make it an exhaust worthy of the SL’s grand-touring character.

Development

Capristo builds the SL500 system from a 3D laser scan of the car, refined in CAD and produced with CNC tooling at its German facility. Each piece is formed from T309 (1.4828) stainless steel and polished by hand. The alloy was chosen for its acoustic character, low weight and long service life under the heat of the 4.7 liter biturbo V8.

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 on the car can be individually tailored to allow specific backpressure margins, determining when the exhaust valves will be triggered. That lets each driver decide exactly how early the valves open.

Vacuum-actuated valved system with programmable control

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.
