Audi Exhaust Pipe Left (S8) - Genuine Audi 4E0253301Q

Product Information

An exhaust pipe is a key part of a vehicle’s exhaust system that channels exhaust gases from the engine’s exhaust manifold through the catalytic converter, muffler, and eventually out of the tailpipe. It helps reduce engine noise, direct harmful gases safely away from the cabin, and support emission control. Exhaust pipes are usually made of steel or stainless steel but can deteriorate over time due to heat, moisture, and road salt.

• Excessive noise – loud rumbling or hissing sounds from cracks, holes, or disconnected pipes.
• Exhaust leaks – visible fumes or a strong smell of exhaust near the vehicle, sometimes entering the cabin.
• Reduced performance – loss of engine power, poor fuel efficiency, or failed emissions tests due to restricted or leaking exhaust flow.

About Genuine Audi

The original parts used by Audi to build your car are available as replacement parts under the “Genuine Audi” brand. Manufactured under the direction of Audi, expect excellent quality and a premium price since these parts are available exclusively through the Audi Dealership network.

You may not realize this, but the parts that make up your Audi are not necessarily manufactured by Audi. No cause for concern, as Audi designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Audi 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 Audi parts box and find an OEM branded part inside, simply with the addition of an Audi 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.
