How are the valves controlled on this Capristo Stelvio Quadrifoglio exhaust?

Valve position is controlled through the included CES-3 programmable exhaust remote kit. It reads exhaust back-pressure and opens the butterfly valves at a preset threshold under acceleration, and a key fob lets the driver set Cruise, Sport, or Open mode directly rather than relying on the factory drive modes.

Is the CES-3 remote kit included or a separate purchase?

The CES-3 programmable exhaust remote kit is included with every Capristo Stelvio Quadrifoglio exhaust system. It ships with a 444 MHz key fob, vacuum solenoid, and a pre-wired harness that only needs power and ground to install.

What happens to the valves if the CES-3 kit loses power?

The CES-3 has a built-in failsafe that leaves the valves fully open in the event of an electrical or vacuum fault, which protects the engine from potential damage until the fault is resolved.

What tip finishes are available on this Capristo Stelvio Quadrifoglio exhaust?

The carbon tips are available in a choice of black or silver finish, both built from the same Type L carbon fiber weave with a hand applied German clear coat.

Description

Capristo Valved Exhaust System with Carbon Tips for 952 Alfa Romeo Stelvio Quadrifoglio

The Capristo Stelvio Quadrifoglio exhaust replaces a factory system that keeps the 690T V6 quieter than an engine with this pedigree deserves, an engine developed by Ferrari engineers off the F154 architecture and shared with the Giulia Quadrifoglio. Capristo manufactures the entire system at its own factory in Sundern, Germany using 3D laser-scanning, CAD design, digital prototyping, and CNC bending and milling, then manually TIG welds every joint and hand polishes the finished piece to a mirror finish. Construction is highest-grade T309 stainless steel, which Capristo notes shares resonance properties with Inconel, the alloy Formula 1 exhaust systems are built from, and the design carries a patented reinforcement aimed at eliminating resonance rather than relocating it further down the system. The tips finish in carbon, built from the same Type L carbon fiber weave grade Ferrari specifies for its own OEM parts, hand laid entirely in a prepreg process with no fiberglass, cured in Italian-built Maroso SRL autoclaves, and finished with a hand applied premium German clear coat. Tips are available in black or silver. It’s a system for a Stelvio Quadrifoglio owner who wants the Ferrari-built V6 heard without turning the cabin of an everyday-usable SUV into a drone chamber at highway speed.

CES-3 Programmable Exhaust Remote Kit

Every Capristo Stelvio Quadrifoglio exhaust system includes the CES-3 programmable exhaust remote kit, which controls the proprietary Capristo valves rather than leaving them tied to the factory drive modes. The control unit reads exhaust back-pressure continuously and opens the butterfly valves at a preset threshold under acceleration, freeing up flow and volume where you want it, while holding more back-pressure at low throttle and low rpm for better torque and everyday drivability. The kit ships with a 444 MHz remote key fob, a vacuum solenoid, and a pre-wired harness that only needs power and ground to install, so there’s no splicing into the factory exhaust wiring. An on-board self-learning function lets you pair additional key fobs, and a built-in failsafe leaves the valves open in the event of an electrical or vacuum fault, protecting the engine from damage. You can also save a default valve setting, so the system starts the way you left it without needing to reselect a mode every time you start the vehicle.
- Cruise Mode: Valves only open at higher exhaust pressure for a quieter, more comfortable drive.
- Sport Mode: Valves open sooner under load for a more aggressive exhaust note and increased performance.
- Open Mode: Valves remain fully open, optimized for track-use or when maximum volume is desired.

About Capristo

Capristo has built exhaust systems out of its own factory in Sundern, Germany since 1990, starting with systems for Ferrari and other exotic manufacturers before expanding into BMW M and other high-performance platforms. Every system is designed in-house using 3D laser-scanning, CAD modeling, digital prototyping, and CNC bending and milling, then hand TIG welded and polished by Capristo’s own craftsmen rather than outsourced to a third-party fabricator. Capristo builds exclusively from T309 stainless steel, a grade chosen for its heat resistance and long service life under repeated thermal cycling, and backs it with a patented reinforced design aimed at eliminating resonance rather than masking it. The result is a company that still manufactures everything at one factory, under one roof, the same way it did on its first exotic-car systems more than three decades ago.

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.
