What do these valve bypass pipes actually do?

The Roma has no mufflers or resonators; Ferrari controls the volume with two exhaust valves that stay closed much of the time, which keeps the car quiet. These pipes bypass those valves with free-flowing straight pipes so the exhaust stays fully open at all times, giving you the twin-turbo V8's full, louder note whenever you drive, not only in the loudest mode.

Will they cause a check-engine light or need a tune?

No. The pipes include electronic valve simulators, so the car's computer still sees the exhaust valves it expects. That means no ECU tune is required and no check-engine light appears, a result Fabspeed guarantees. The car drives normally afterward, just with the full exhaust note available all the time rather than only when the valves open.

How much louder is it, and can I make it quiet again?

Expect a noticeably louder, more authoritative, screaming twin-turbo note. Because the pipes bypass the valves entirely, the exhaust stays open at all times, so there is no quiet valve-closed mode once they are fitted. This is the point of the upgrade, but it is worth knowing if you want a soft cold-start or a quiet cruise, in which case the standard valved setup suits better.

Do the Valve Bypass Pipes for Ferrari Roma remove the catalytic converters?

No. These bypass the exhaust valves, not the catalytic converters, and the car's factory emissions hardware stays in place. Fabspeed describes this as the best way to get a much louder exhaust note while leaving the cats where they are, which is also why the car needs no tune and throws no check-engine light.

Is it a bolt-on installation?

Yes. The pipes were modeled from 3D scans of the factory section, so they are a true bolt-on with no cutting or welding required, rated Level-1 install difficulty. Mechanically confident owners can fit them with a lift and hand tools, though many prefer a specialist handle the swap on a car of this value to confirm a clean, leak-free seal.

What are the Valve Bypass Pipes for Ferrari Roma made from?

They are hand-fabricated from CNC mandrel-bent T304L stainless steel and built entirely in-house at Fabspeed Motorsport in Fort Washington, Pennsylvania. The mandrel bends keep the bore smooth for flow, and the T304L stainless resists corrosion and sustained exhaust heat, giving pipes that perform and last on a car meant to be driven hard.

Description

Fabspeed Supersport Valve Bypass Pipes for Ferrari Roma

Fabspeed’s Valve Bypass Pipes for Ferrari Roma are the simplest way to unleash the twin-turbo V8’s full voice. The Roma runs no mufflers or resonators at all; Ferrari uses two exhaust valves to hold the volume down, and they stay shut most of the time, so the car is far quieter than it should be. These hand-fabricated CNC mandrel-bent T304L stainless pipes bypass those valves to keep the exhaust open all the time, for the louder, more authoritative screaming note the Roma was built to make, while valve simulators keep the system tune-free with no check-engine light, guaranteed. Shaped from 3D scans of the factory section and built in-house at Fabspeed, they bolt straight in and leave the factory emissions hardware in place.

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.
