What is included, and what are the 250-cell sport cats?

This package includes the Capristo valved catback exhaust and 250-cell sport cat downpipes, along with the CES-3 control module and key-fob remote. The 250-cell sport cats are high-flow catalytic converters with a dense 250-cell core that free up exhaust flow in comparison to the Factory Equipment. It does not include exhaust tips, which Capristo offers separately.

Will the 250-Cell Sport Cat Downpipes fit my McLaren 720S?

The 250-Cell Sport Cat Downpipes and valved catback in this package are designed for the McLaren 720S from 2017 to 2023 with the 4.0L twin-turbo V8 (M840T). They use the car's OEM mounting points for a direct fit. If you have a 720S Spider or another McLaren, confirm fitment with us before ordering.

How does the CES-3 valve control work?

The system uses adaptive valves controlled by the included CES-3 module and a key-fob remote. Cruise opens the valves only at higher RPM for a quieter drive, Sport opens them earlier and under hard acceleration, and Open keeps them open all the time. You can set the Cruise and Sport backpressure thresholds independently to fine-tune the balance.

How is this different from the race-downpipe version?

This version uses 250-cell high-flow sport cats and is the more reserved of the two setups. The race-downpipe version uses straight stainless downpipes, is built for off-road and competition use and gives a louder, freer-flowing result. Choose this package for a strong gain with a more civilized sound, or the race version for the most aggressive setup where permitted.

Is this system legal in California?

No. Even with 250-cell sport cats, this system is not CARB approved and is not for sale or use in California or other states that require CARB certification, and it may trigger a check engine light. It is intended for use elsewhere where permitted, and it is the buyer's responsibility to confirm local regulations before purchase and installation.

The system is made from T309 (1.4828) stainless steel, hand-polished and built in Capristo's German workshop. The stainless construction is chosen for its sound character, reduced weight, and durability at high exhaust temperatures. It uses the car's OEM mounting points, so it fits in the factory location.

Description

Capristo Valved Catback Exhaust System w/ 250 Cell Catted Downpipes for McLaren 720S

This Capristo package pairs the brand’s valved catback exhaust with 250-Cell Sport Cat Downpipes, the complete system for McLaren 720S owners who want a serious jump in sound and flow through high-flow sport cats. The valved catback and included CES-3 control let the driver move the sound from refined to aggressive through a key-fob remote, while the 250-cell sport cat downpipes free up the exhaust path, making this the most civilized of Capristo’s 720S downpipe packages. Built in Germany from T309 stainless steel, it is a complete Capristo exhaust upgrade for the 720S, finished to the standard the car deserves.

Valve Dynamics

In this system, adaptive valve flaps are integrated which adjust their positions in response to both the prevailing driving conditions and the inputs received from the driver. At lower engine speeds and during cruising periods, the valves are deliberately kept in a closed state, emanating a richer exhaust sound. On the contrary, when the throttle is fully engaged, the valves broaden, revealing the entire harmonic spectrum of the engine.

Engineering

Capristo develops the 720S catback and 250-cell downpipes together with 3D laser scanning, CAD design and CNC tooling at its German workshop, so the package bolts to the OEM mounting points as one system. Each component is formed from T309 (1.4828) stainless steel and polished by hand. The alloy was chosen for acoustic transparency, low weight and durability behind the M840T twin-turbo 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 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.

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.
