BMW Exhaust Flange Gasket - Genuine BMW 18111178137

Product Information

An exhaust pipe flange gasket is a sealing component placed between two sections of the exhaust system, typically where pipes or flanges are bolted together. It prevents exhaust gas leaks, reduces noise, and helps maintain proper backpressure for engine efficiency. Made from heat-resistant materials like graphite or metal composites, the gasket ensures a secure, long-lasting seal under extreme temperatures and vibrations.

• Loud exhaust noise, especially near the flange connection.
• Visible exhaust leaks or soot marks around the gasket area.
• Reduced engine performance or fuel efficiency, due to loss of proper exhaust flow.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
