PROFILE
The ARM MK7 4.5" GTI Downpipe is an essential upgrade if you're looking to get the most from your Gen 3 EA888 equipped GTI. With it's full 4.5" body, the ARM MK7 4.5" Downpipe gives you unsurpassed exhaust flow and sound for your 2.0T. Whether you are running the stock IS20, upgraded IS38, or hybrid turbo, the ARM 4.5" Downpipe is the perfect downpipe upgrade to support any build.
The stock downpipe is built with a dense catalyst that hinders 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 4.5" GTI 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 remarkable improvement in exhaust note.
The ARM 4.5" Downpipe doesn't just give you more power, it delivers an exhaust note that commands attention. Enjoy a rich, aggressive tone under acceleration, with no drone. This perfect balance of sound and performance makes every drive something to look forward to. 
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.
For the ultimate combination of power, sound, and performance, pair the ARM MK7 GTI 4.5" Downpipe with the ARM GTI Exhaust Together, these upgrades create a system designed to maximize airflow, performance, sound and delivers an unforgettable driving experience.
CONSTRUCTION
Made of TIG welded T304 grade stainless steel, the ARM MK7 4.5" GTI Downpipe is designed to fit your MK7 GTI perfectly. The ARM MK7 GTI 4.5" Downpipe is constructed of a single piece. This solid-unit construction eliminates the exhaust leaks and installation issues commonly found with it's multi-piece downpipe counterparts.
Featuring a cutout near the upper section, this downpipe ensures proper clearance around the sensitive ABS module. This design eliminates the risk of contact or heat-related damage to critical brake components, ensuring both performance and reliability without compromising performance.
The laser-cut mounting bracket and CNC machined mounting prongs make for a precise fitment to your stock downpipe mounting points.
The ARM MK7 4.5" GTI Downpipe kit comes with both a 2.5" reducerto connect to the stock exhaust system, and a 3" adapterto 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.
The ARM MK7 4.5" GTI 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 from torsion during hard acceleration, cornering, and braking.
The ARM MK7 4.5" 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.
