PROFILE

The ARM Audi 8V A3 Downpipe is an essential upgrade if you're looking to tune your Gen 3 EA888 equipped VW.  The stock downpipe robs your EA888 engine with high back-pressure suffocating your turbo and stifling your power goals.  Replacing your OEM downpipe with the ARM 8V A3 Downpipe will significantly improve exhaust flow, reducing the back-pressure generated by your turbocharger.  The result of the increased exhaust flow is faster turbo spool, increased power and torque, and a nice improvement in exhaust note.    

In addition, the improved exhaust flow will allow you to run increased boost targets commonly found with advanced Stage 2+ tuning software.  Attempting to run Stage 2+ tuning files over 25psi with the stock downpipe can put excessive stress on your turbocharger and is not recommended.  

CONSTRUCTION

Made of TIG welded T304 grade stainless steel, the ARM 8V A3 Downpipe is designed to fit your 8V A3 perfectly.  The ARM 8V A3 Downpipe is constructed of a single piece design.  This solid-unit construction eliminates the exhaust leaks and installation issues commonly found with it's multi-piece downpipe counterparts. 

The laser-cut mounting bracket and CNC machined mounting prongs make for a precise fitment to your stock downpipe mounting points.  

The ARM 8V A3 Downpipe kit comes with both the reducer to connect to the stock exhaust system, or a straight 3" adapter to connect to your upgraded cat-back exhaust.  This connection utilizes a CNC machined v-band system for connecting between the downpipe and adapter of your choice.  The v-band is a superior connection type compared to a slip-fit or bolt on connection as it maintains a more study and reliable seal between the two ends.  

The ARM 8V A3 Downpipe incorporates a stainless steel flex section between the turbo and mid-pip mounting point.  The addition of this flex section reduces tension on turbocharger caused from torsion during hard acceleration, cornering, and braking. 

The ARM 8V A3 Downpipe gives you an immediate improvement in turbo spool, power and torque.

-RESONATED OR CATTED

-The ARM 8V A3 Catless Downpipe comes with a single 4" Resonator as standard on our catless downpipe option.

-Optional 200 Cell High-Flow Catalyst: Replaces the resonator on the standard catless downpipe and reduces exhaust fumes and chance of getting a check engine light (CEL). 

-Catalyst in OEM position: Does not require O2 extension wires, and properly warms up compared to downstream catalyst placement
