The Catted ARM MK7 GTI Downpipe is an essential upgrade if you're looking to get the most out of your Gen 3 EA888 equipped GTI. The stock downpipe is constructed with a dense catalyst that impedes exhaust flow on your EA888 engine, causing higher back pressure, increasing turbo lag and causing your turbo to work harder.
Replacing your OEM downpipe with the ARM MK7 GTI downpipe will dramatically improve exhaust flow, reducing the back pressure generated by your turbocharger. The result of the increased exhaust flow is a faster turbo spool, increased horsepower and torque, and a nice improvement in exhaust note.
Additionally, the improved exhaust flow will allow you to run increased boost targets found with Stage 2+ tuning software. Attempting to run Stage 2+ tuning files over 25 psi with the stock downpipe can put excessive pressure on your turbocharger and is not recommended. Most tuners require an upgraded downpipe to run their most aggressive tunes.
CONSTRUCTION
Made of TIG welded T304 grade stainless steel, the ARM MK7 GTI downpipe is designed to fit your MK7 GTI perfectly. The ARM MK7 GTI downpipe is constructed in one piece. This solid unit construction eliminates exhaust leaks and installation issues commonly experienced with its multi-piece downpipe counterparts.
