Does it work with the factory PSE button?

Yes, completely. The Helical valves tie into the existing PSE control rather than replacing or bypassing it, so there is no additional controller and no wiring to run. PSE off closes the valves and the car is quiet; PSE on opens them and it is not. Nothing changes about how you operate the car.

Will it drone on the highway?

No. With the valves closed Fabspeed describes the note as subdued and completely drone-free, with cabin conversation as clear as it is on the factory system. That matters more than peak volume on a car people actually travel in, and it is the specific reason the valved version is worth its price over a fixed system.

How much power does it add?

On Fabspeed's AWD Dynojet, 48.7 wheel horsepower and 53.7 lb-ft at 4,800 rpm, which is roughly 55 horsepower at the crank. Just as useful is what happens low down: 19.6 whp and 32.7 lb-ft at 3,100 rpm as the turbos spool faster. Results vary with the car and conditions.

Is it street legal, and will it affect my warranty?

Fabspeed states this cat-back system is emissions legal in all fifty states and worldwide, and that it has no effect on the factory Porsche warranty. Being cat-back, it starts behind the factory emissions hardware and leaves it untouched, which is what makes both claims straightforward here.

Do I need Dual Tips or Quad Tips?

Whichever your car left the factory with. Fabspeed builds this system in both configurations to match the two OEM tip arrangements on the 992 Turbo, and they are not interchangeable, so check the back of your car before selecting at checkout. If you are unsure, send us a photograph and we will confirm.

How does it compare with the titanium system?

Both are cat-back, both use Helical valves and both retain full PSE control. The titanium system saves more weight, sixteen pounds against this one's 9.8, and has a harder-edged tone from the material itself. This one is stainless and costs considerably less, which is why most 992 Turbo owners land here.

Fabspeed Valvetronic Maxflo Exhaust System for 992 Porsche 911 Turbo & Turbo S

Fabspeed’s Valvetronic Maxflo Exhaust System for the 992 Porsche 911 Turbo and Turbo S is the rare exhaust that gives up nothing on either side of the argument. With PSE engaged and the valves open it produces close to forty-nine wheel horsepower and fifty-four lb-ft over standard, with deep tones, crisp overrun pops and the turbochargers brought forward in the mix. With PSE off and the valves closed it is quiet, refined and completely free of drone, with cabin conversation as easy as it is on the factory system. Fabspeed has been building valved exhausts for every Porsche twin-turbo since the 993 Turbo in 1996, and their thirty years on this platform shows in how completely this system disappears into the car: it is plug-and-play with the factory PSE, laser scanned and CAD designed to OEM geometry, emissions legal in all fifty states, and it has no effect on the factory warranty. Nothing about it asks the owner to compromise.

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.
