ARM Motorsports Catted Downpipe For B9 Audi S4/S5 3.0T

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! 

The OEM 3.0T downpipe utilizes a large 800 cell catalyst that restricts vital airflow out of the engine. The ARM B9 3.0T Downpipe replaces this restrictive section of the exhaust with a 200 cell catalyst, allowing you to free up more power from your 3.0T!

A tune is not requiredto run the ARM B9 3.0T Downpipe, but pairing it with a tune will greatly increase the output of your 3.0T. 

Construction:

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.
