ARM Motorsports DOWNPIPE Volkswagen MK7 Golf GTI GLI | Audi 8V A3

The ARM MK7 GLI 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 MK7 GLI 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.  

The ARM MK7 Downpipe gives you an immediate improvement in turbo spool, power and torque.  Pairing the ARM MK7 Downpipe with a proper tune will yield gains up to 60whp and 105wtq on the stock IS20 turbocharger.
