The ARM B9 S4 Catted Downpipe gives your Audi 3.0T EA839engine all the power with less emissions! It allows for more exhaust flow from the turbocharger while keeping exhaust fumes lower. This allows your 3.0T to spool faster, increasing power, and improving throttle response, especially in the lower RPM range. On top of all of these performance benefits, the ARM B9 3.0T Downpipe upgrade opens up the sound of your 3.0T especially when paired with the ARM B9 Midpipes, giving you the sound to match!
Check out the video below to hear the sound difference the ARM Downpipe and ARM Midpipes makes versus the OEM downpipe and midpipes.
Unlock the full potential of your 3.0T setup by pairing the ARM B9 Downpipe with the ARM B9 3" Midpipes. On their own, each gives you a boost in power and sound, but if you're looking to get the most out of your B9 setup, pairing them together will perform and sound incredible. These two parts replace the biggest restrictions in the stock B9 exhaust setup, helping your turbo spool faster, your exhaust flow more freely, and your car sound much more aggressive—all while retaining your factory exhaust valves. Built to fit perfectly and work in sync, the ARM B9 Downpipe and Midpipes combination delivers the ideal setup for your EA839.
The ARM B9 3.0T Downpipe upgrade starts at the turbocharger where we have a precision CNC machined turbo flange to match the OEM turbo, or any turbo upgrade that fits the OEM downpipe.
From there the ARM B9 S4 Downpipe has a massive 6.5" catted section to maximize exhaust flow straight off the turbo, which then transitions to a 3.5" Y-section. The midpipe flanges on the ARM B9 3.0T Downpipe are precision cut and designed to mate up to either the OEM B9 midpipes, or the ARM B9 Midpipes. Pairing the ARM B9 3.0T Downpipe with the ARM B9 Midpipes creates an exotic and intoxicating exhaust note that will leave you grinning ear to ear.
The ARM B9 3.0T Downpipe comes with gaskets and hardware for the midpipe connection.
