Audi A4/S4 Downpipes

About

AUDI A4 or S4 Downpipes If you’re looking to get more out of your Audi A4/S4’s performance, an upgraded downpipe might be exactly what you’re looking for. With our Audi A4/S4 downpipes collection (including more options for B8, B8.5 & B9 platforms), you get smoother exhaust flow, faster turbo spool and the aggressive tone you desire. The benefits of upgraded downpipes doesn’t just stop at better performance: High-flow Design: Cuts down backpressure, allowing your turbo to breathe High quality T304 Stainless Steel: Built to handle extreme heat (1400°F+) without cracking Mandrel-Bent Piping: Allows for a consistent diameter through every bend in the pipe for smooth flow. Model-Specific Fit: Built for A4 2.0T, S4 3.0T models for easy implementation. Why Upgrade Your Downpipe? With a turbocharged Audi A4 or S4, the hot exhaust is used to spin the turbo, which is cooled and compressed before being forced into the engine. With more compressed air in the engine, you burn fuel faster, and in turn get more horsepower out of your car. All that hot exhaust recycled by your turbo needs to go somewhere. This is where your downpipe works its magic. It allows your turbo to perform optimally by letting out excess hot air with ease. Since our downpipes are mandrel-bent, you get a more consistent diameter through the pipes, allowing for easier flow. It’s the upgrade that you’ll notice on the road and the perfect base for future performance upgrades.
