The ARM MK7 Golf 1.8T Catted Downpipe is an essential upgrade if you want 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 a 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.

CONSTRUCTION

Made of TIG welded T304 grade stainless steel, the ARM MK7 Golf 1.8T Downpipe is designed to perfectly fit your MK7 Golf 1.8T. 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 its 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 MK7 Golf 1.8T Downpipe kit has a 60mm reducer to connect to the stock exhaust system and a 3" adapter to connect to upgraded cat-back exhaust systems. This connection utilizes a CNC machined v-band system for connecting the downpipe and adapter of your choice. The v-band is superior to a slip-fit or bolt-on connection as it maintains a more sturdy and reliable seal between the two ends.

The ARM MK7 Golf 1.8T Catted Downpipe comes with a single 200 Cell High-Flow Catalyst to reduce emissions and exhaust odors commonly found with catless downpipes.

The ARM MK7 Golf 1.8T Downpipe incorporates a stainless steel flex section between the turbo and mid-pipe mounting point. The addition of this flex section reduces tension on the turbocharger caused by torsion during hard acceleration, cornering, and braking.

The ARM MK7 1.8T Downpipe immediately improves turbo spool, power, and torque. Pairing the ARM MK7 Downpipe with a proper tune will yield gains up to 40whp and 74wtq on the stock IS12 turbocharger.
