This little piece basically seals the connection between sections of your exhaust pipe. It slides over the end of one pipe and then another pipe slides over it, creating a tight, gas – tight seal. It’s often used where two pipes join together and needs a bit of flexibility to allow for movement and vibration. It's not designed to be a long – term solution, more of a temporary fix or for situations where a full weld isn't practical. Think of it as a connector, bridging the gap between exhaust pipes. It allows exhaust gases to flow smoothly from the engine, through the catalytic converter, muffler and out the tailpipe. It’s positioned on the back pipe, which is the section of exhaust coming from the muffler, heading towards the rear. It helps maintain exhaust flow and prevents leaks. Exhaust leaks are no good. They can reduce your engine’s efficiency, meaning you'll get worse gas mileage. More seriously, those gases are toxic – carbon monoxide is a big concern, and you don't want that getting into the cabin of your vehicle. A failing or missing pipette tip will definitely cause exhaust leaks, and you’ll notice if one develops – you'll likely hear a hissing or chugging sound, especially when accelerating, and you might smell exhaust fumes. They aren't hugely expensive, and replacing one is often a quick fix. You can find them pretty easily; Fixparts Online has a good selection. It acts like a shield preventing harmful gases from escaping and keeps everything running as it should. Volkswagen quality assured: Pipette Tip (MPN 3AA253684A) comes with a 12-month warranty!
