Kline Innovation Valvetronic Exhaust System for Ferrari SF90 Stradale

Kline Innovation focuses on the Ferrari SF90 Stradale, a vehicle commemorating the 90th anniversary of the SF90 Formula One car, as its latest project. This new flagship model from Ferrari, boasting a total power output of 986hp, retains the traditional 4.0L V8 engine, which alone produces 769hp. However, one notable downside is the loss of the iconic Ferrari V8 howl, replaced by the sound of the turbo spool. The primary objective of Kline Innovation is to recapture and restore the distinctive howl of the Ferrari in the SF90 model.

The Sound

  • Utilizing high-flow catalysts or race pipes significantly amplifies the volume, while Kline Innovation’s unique 1D CLR tight radius X-pipe adjusts the pitch to the iconic sound expected of a Ferrari. Constructed from the highest quality F1 grade Inconel 625 superalloy, the design not only substantially reduces weight but also imparts a distinct tonal characteristic to the SF90, a feature exclusive to the Kline Inconel range. The Kline exhaust system features a valvetronic mechanism, integrating seamlessly with the original valve control system and including two SF90-specific, harmonically tuned micro silencers. This allows for quiet driving with no cabin resonance during cruising, yet delivers the full, unrestricted scream of a Ferrari when the valves are open.

The Specifics

  • Catalyst: Race pipes available for optimum sound and performance, or a choice of 100 or 200 cell high flow sports cats
  • Cross Section: 76mm valve open free flow transit (unsilenced), 45mm valve closed silenced transit
  • Materials: Available in premium grade Inconel 625 superalloy or 304 grade stainless steel


  • 2019+ Ferrari SF90 Stradale: 4.0L TT V8 F154


  • It’s important to note that while some images may feature optional cat-pipes, they do not come as standard inclusions with the system

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 sales@bulletproofautomotive.com with any inquiries.
