What does the Kline Innovation Valvetronic Exhaust System for 992.2 fit?

This system is built specifically for the Porsche 911 Turbo S on the 992.2 chassis, the only 911 currently built with a hybrid powertrain. The rear silencer is built in F1-grade Inconel 625, paired with your choice of X-pipe material and configuration.

Is this system available in stainless steel, or only Inconel?

The rear silencer is built in F1-grade Inconel 625. The X-pipe paired with it is available in either Inconel or 304 stainless steel, so you can match materials or mix them depending on budget.

Can I add carbon fiber exhaust tips to this system?

Yes. Kline lists carbon fiber exhaust tips as an option for this system.

How does the valvetronic system work?

With the valves closed, the exhaust holds a refined, sophisticated note with no cabin drone for daily driving. Open the valves and the tone builds into an aggressive, F1-inspired crescendo that sharpens with revs, giving the driver full control over the car's exhaust character.

Description

Kline Innovation Valvetronic Exhaust System for 992.2 Porsche 911 Turbo S

Kline Innovation’s Valvetronic Exhaust System for the 992.2 Porsche 911 Turbo S answers the one compromise the car’s factory exhaust still makes: a note tuned down rather than tuned for effect. Every Kline system is designed and built in-house, from laser scanning and CNC mandrel bending to autoclave carbon fiber work, the same processes the company applies to low-volume commissions for manufacturers like RUF Automobil and W Motors. For the 992.2 Turbo S, the only 911 currently built with a hybrid powertrain, that means an F1-grade Inconel 625 valvetronic rear silencer paired with your choice of X-pipe, available in Inconel or 304 stainless steel and in 100-cell, 200-cell, or Race configurations, built to sharpen the twin-turbo flat-six into a higher-pitched, more exotic voice on demand. It is a system for an owner who wants the 911 Turbo S matched by a voice that sounds every bit as engineered.

Construction

The Inconel 625 rear silencer uses ultra-thin 0.7mm walls and weighs 8kg on its own. Paired with Kline’s 200-cell Inconel X-pipe at 9kg, the complete system weighs 17kg against the factory rear system’s 28kg, an 11kg weight saving; other X-pipe configurations and the stainless X-pipe option carry different weights. Every build pairs the Inconel rear silencer with your choice of X-pipe material, Inconel or 304 stainless steel, and configuration, 100-cell, 200-cell, or Race. Both the silencer and X-pipe can be finished with optional carbon fiber exhaust tips.

Sound and Control

With the valves closed, the exhaust holds a refined, sophisticated note with no cabin drone for daily driving. Open the valves and the tone builds into an aggressive, F1-inspired crescendo that sharpens with revs, giving the driver full control over the car’s exhaust character.

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.
