Capristo FreeFlow Exhaust System for Ferrari F355

Enhanced horsepower and an intensified sound profile are achieved by optimizing the exhaust system’s efficiency. Capristo Exhaust, the developer of this exhaust system, has meticulously crafted it to unveil the authentic essence of the F355.

Performance enhancement

  • The initial concept for this system was centered around elevating performance and enhancing the acoustic profile, with its internal components designed to enhance flow and replicate the distinctive Ferrari F1 sound. This exhaust system is not only lighter but also exhibits superior heat dissipation capabilities, resulting in improved performance metrics, including enhanced torque and throttle response.


  • In some driving scenarios, when the original bypass valve of Ferrari 355 vehicles is in the open position, a reverse flow through the silencer can cause overheating and damage to the headers. This occurs because, with the valve open, not all exhaust gases flow through the main catalytic converter; instead, most flow through the bypass. This creates a vacuum at the exit leading to the main catalytic converter, causing hot exhaust gases in the muffler to be drawn backward through the main catalyst, further heating the gases.
  • This cycle continues when the exhaust gas valve is open, generating increasing heat. Although Ferrari made modifications in 1996 to address this issue, it was not completely resolved. The problem lies in the extreme back pressure created when all exhaust gases, including those aspirated backward, must pass through a single exhaust gas valve.
  • To combat these issues, Capristo exhaust systems were designed differently. They route exhaust tubes from the main catalytic converter to the outer end pipes and those from the bypass to the inner end pipes, preventing the mixing of hot exhaust gases with cold air. This not only maintains exhaust temperature but also eliminates the excessive back pressure caused by a single bypass valve, ensuring optimal performance.

Muffler Options

  • No matter if your preference leans towards a quiet hum or a resounding roar, you have the option to adjust your vehicle’s exhaust tone to align with your individual style and tastes. This system offers a choice of three distinct sound profiles to cater to your preferences.
    • Sound 1: 10 dBA louder than OEM
    • Sound 2: 18 dBA louder than OEM
    • Sound 3: Generates Ferrari-F1-like sound

Exemplary Engineering

  • Every single element found in the Capristo Exhaust collection serves as a testament to the highest level of engineering excellence. This meticulous journey begins with state-of-the-art 3D Laser-Scanning and culminates with precise CAD Design and CNC machining, all carried out with exacting precision within their advanced German facility. Crafted from the esteemed T309 (1.4828) Stainless Steel and embellished with a refined finish, these exhaust systems epitomize acoustic sophistication, elegant aesthetics, and unwavering durability, evoking the spirit of the legendary F1 Inconel.

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.
