Moshammer Turbo X-Pipe Race Exhaust for 991 Porsche 911 Turbo & Turbo S

Moshammer Turbo X-Pipe Race Exhaust is aimed at 991 Turbo and Turbo S owners who use their cars on circuit and want the exhaust to keep up. It replaces the factory equipment section with a crossover X design, saving significant weight against the original system and running much lower exhaust backpressure. Lower backpressure means lower exhaust temperatures and a freer breathing engine, and Moshammer states the gains arrive without any software changes. It is a direct bolt-on that uses the original screw points and clips and fits the original muffler sets, and mounting material is included with article P991.20.4080. This is a motorsport component for closed-course use only, made to order in Berlin in small batches.

Motorsport Intent

This section is sold for motorsport and closed-course use only, not for the road. It replaces the factory equipment section of the 991 Turbo exhaust with a crossover X design, which is the reason it belongs on a track car. Keep the original section if there is any chance the car will need to return to standard specification.

Construction and Fit

Installation is a direct bolt-on using the original screw points and clips, and the section is made to fit the original muffler sets. Mounting material is supplied with the part, so a specialist workshop has everything needed on the day. Moshammer builds each one in Berlin in small batches with the fit and weld quality that implies.

Sound and Character

The note is deep and aggressive, and on a Turbo it brings out the induction and turbo sounds owners chase in the first place. Less weight and less backpressure sharpen throttle response alongside the noise, and Moshammer notes that torque improves without a software upgrade. Exhaust temperatures drop at the same time, which is the benefit you feel on the third lap rather than the first.

About Moshammer

Moshammer Automotive is a Berlin-based manufacturer of OEM+ aerodynamic refinement for Porsche, with a smaller line for Mini, Audi, BMW, and Mercedes-Benz. The house style is restraint with intent: parts drawn to look as though the factory had gone one step further, developed against original mounting points, TUV-documented where German road use demands it, and produced in small batches rather than stocked in volume. Their catalog spans single accents such as vent grills and wing end blades through complete Downforce and Tradition RS aero programs, alongside a range of multipiece forged wheels made to order in any size, width, and finish.

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.
