Will the Slip-On Turndown Tips fit my 991.2 GT3 or GT3 RS?

Yes. The Slip-On Turndown Tips fit the 2017-2019 991.2 Porsche 911 GT3 and the 2018-2019 991.2 GT3 RS. They are designed for Porsche GT3 OEM-style centre mufflers and for Fabspeed's own GT3 exhaust systems, and install as a bolt-on with no cutting or welding.

Which configuration should I order?

If your car is on the factory exhaust, take the complete kit, which includes the holders and all the mounting hardware. If you already run a Fabspeed exhaust system or the Fabspeed Deluxe Dual Style Tips, the holder is already fitted, so take the version for Fabspeed systems and save the cost of hardware you do not need.

How much quieter do they actually make the car?

Typically 3 dB or more, measured. That is not a dramatic figure in isolation, but at a circuit enforcing a 92 or 95 dB limit it is often the whole margin. Aiming the outlets straight at the ground gives the largest reduction; aiming them left or right lets you direct noise away from a monitor at a specific point.

Can I adjust them at the track?

That is the point of them. Loosen the clamp, swivel the pipes to where you need them, and retighten. It takes a minute in the paddock, which means you can respond to an actual reading from the sound monitor rather than committing to a setting before you leave home.

Do I have to take them off for road driving?

No, though most owners do. Nothing about them prevents road use, but they are a competition part and the straight-down aim that gives the best noise reduction is not what most people want on the street. Swapping back to standard tips takes minutes, which is why many owners run these alongside the Deluxe Dual Style Tips.

What are they made from and are they warrantied?

T304L stainless steel, water jet precision CNC cut and hand welded. T304L is the low-carbon grade chosen for weld quality and for resisting the corrosion and heat cycling that seize an adjustable clamp joint over time. Every Fabspeed performance product carries the Fabspeed lifetime warranty.

Fabspeed Competition Slip-On Turndown Tips for 991.2 Porsche 911 GT3 & GT3 RS

Fabspeed Slip-On Turndown Tips solve a problem that only exists at the track, and they solve it in about the time it takes to walk back to the paddock. Sound monitors at decibel-limited circuits do not measure how fast you are, they measure what reaches a microphone at a fixed point, and a 991.2 GT3 aimed straight at one will read higher than the same car aimed at the ground. Fabspeed’s answer is a pair of adjustable 90 degree turndown outlets in hand welded T304L stainless. Loosen the clamp, swivel them left, right or straight down, and you are typically 3 dB quieter than you were a minute ago. Nothing about the car changes. Nothing about the exhaust changes. Only where the noise goes.

Notes

If your car has the factory exhaust, choose “Complete Kit With Holders and Turndown for OEM” at checkout. That version includes the mounting hardware you will need.
If you already run a Fabspeed exhaust system or the Fabspeed Deluxe Dual Style Tips, choose “For Fabspeed Exhaust System or Dual Style Tips” instead, since the holder is already on the car.
These share their holder with the Fabspeed Deluxe Dual Style Tips for 991.2 Porsche 911 GT3 & GT3 RS, so the two can be run on the same car and changed depending on where you are driving
Also fits Fabspeed’s 991.2 systems including the Center Mini Maxflo Performance Exhaust System and the Rennsport Muffler System
All Fabspeed products are expected to ship within one week of order, though timelines are often much quicker

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.
