The ARM MK7 Golf 1.8T Catted Downpipe is an essential upgrade if you're looking to get the most from your 1.8T equipped Golf.  The stock downpipe is built with a dense catalyst that hinders exhaust flow on your 1.8T engine, causing higher back-pressure, increasing turbo lag and causing your turbo to work harder. 

Replacing your OEM downpipe with the ARM MK7 Golf 1.8T 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 found with 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.  Most tuners require an upgraded downpipe to run their more aggressive tunes.  

Made of TIG welded T304 grade stainless steel, the ARM MK7 Golf 1.8T Downpipe is designed to fit your MK7 Golf 1.8T perfectly.  The ARM MK7 Golf 1.8T 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 ARM MK7 Golf 1.8T Downpipe kit comes with both a 60mm reducer to connect to the stock exhaust system, and a straight 3" adapter to connect to upgraded cat-back exhaust systems.  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.
