What is the difference between the stainless steel and Inconel versions of this exhaust?

Inconel is a nickel-chromium alloy that is lighter than stainless steel and handles higher sustained temperatures more effectively. On a high-output platform like the Temerario, Inconel is the stronger choice for track use or extended high-load driving where heat management matters most. The stainless version is the baseline option and suits street-focused builds.

What does the 999 fine-gold plating add over standard Inconel?

The gold-plated Inconel version adds a layer of thermal reflectivity at the surface, reducing heat radiation away from the exhaust into the surrounding engine bay. It also provides a visually distinctive finish. The underlying construction and heat protection are the same as the standard Inconel version.

Can the exhaust flaps be controlled manually, or do they only respond to drive mode changes?

Flap actuation on NOVITEC valved exhaust systems follows the vehicle's drive mode logic by default. For manual cockpit control independent of drive mode, the NOVITEC SWITCHTRONIC module can be added to the build.

Description

NOVITEC Exhaust System w/ Flap-Regulation for LB634 Lamborghini Temerario

The NOVITEC Temerario exhaust with flap-regulation brings NOVITEC’s valved exhaust system to the all new Lamborghini Temerario platform, giving drivers switchable control over the exhaust tone directly from the cockpit. The flap-regulated design allows the exhaust character to shift between a refined note for daily use and a more aggressive output when the situation calls for it, without committing to one or the other permanently the way a non-valved system does. Built to handle the thermal demands of the Temerario’s powertrain, the system is fully covered in high-temperature heat protection throughout. Three material configurations are available; stainless steel with full heat protection, Inconel with full heat protection, and Inconel with full heat protection and 999 fine-gold plating for maximum thermal reflectivity and a visually distinctive finish. Available in stainless steel, Inconel, or 999 fine-gold plated Inconel.

About NOVITEC

Based in Stetten, Germany, NOVITEC is known for building platform-specific exhaust and engine-bay solutions for modern Ferrari applications where packaging, temperatures, and drivability matter as much as peak numbers. For the Daytona SP3, that experience shows up in the use of metal catalysts, comprehensive thermal insulation, and flap regulation that lets the car stay controllable and comfortable without giving up the top-end sound and response you expect from a naturally aspirated V12.

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.
