Capristo Valved Exhaust System for Maserati M138 Coupe / GranSport / Spyder

The renowned Capristo Valved Exhaust System provides a versatile auditory experience, capable of delivering a robust exhaust note during acceleration while maintaining a subtler sound for urban commuting.

Valve Dynamics

  • This system incorporates flexible valve flaps designed to adjust their positions in harmony with the current driving conditions and driver’s inputs. During lower engine speeds and cruising intervals, the valves are intentionally maintained closed, emitting a deeper exhaust resonance. Conversely, when the throttle is fully engaged, the valves unfold, unleashing the full symphonic range of the engine.

Artisan Craftmanship

  • Capristo exhaust systems exemplify the union of sophisticated craftsmanship and cutting-edge technologies, including 3D Laser-Scanning, CAD Design, Digital Modeling, and CNC machining. Every component is intricately created in our respected German workshop, utilizing high-quality T309 (1.4828) Stainless Steel. Celebrated for its impeccable acoustic purity, balanced weight properties, and enduring robustness, this alloy is parallel to the Inconel materials featured in premier F1 events. Each nuance is meticulously hand-polished to a luminous sheen, underscoring our steadfast commitment to supreme excellence.

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 vehicle’s Cruise and Sport modes can be independently configured to establish specific backpressure limits, which subsequently determine the activation times of the exhaust valves. This provides exact control over the exhaust system, enabling modifications to accommodate the driver’s distinct preferences and resilience.

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.
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.
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 with any inquiries.
