ARM Motorsports MK5 GTI 3" CATTED DOWNPIPE

The ARM Motorsports MK5 GTI 3" Catted Downpipe delivers impressive gains of up to +20whp and +30wtq while dramatically improving turbo spool and exhaust flow on the 2.0T platform. Designed for CBFA and CCTA engines, this downpipe reduces backpressure, helps the turbo reach target boost sooner, and enhances exhaust tone without introducing excessive rasp.

A catted downpipe offers several advantages over a catless setup. The 200-cell sport catalytic converter assists in emissions compliance*, reduces strong exhaust odors commonly associated with catless downpipes, and refines overall sound quality by reducing high-pitch rasp. Enthusiasts seeking performance, drivability, and a more balanced exhaust tone will appreciate the benefits this catted design provides.

Constructed from full 3" stainless steel, the downpipe utilizes smooth mandrel bends, a CNC-machined turbo flange, and an integrated flex joint for durability and easier installation. The 200-cell catalyst is placed in the mid-section for optimal efficiency, and the design supports both OEM and aftermarket cat-back systems. Included is a 3" to 2.25" reducer to allow perfect fitment with the factory exhaust, or you may connect directly to a 3" aftermarket system for a true turbo-back setup.

Engineered for reliable performance and upgraded flow, the ARM MK5 GTI Catted Downpipe is also compatible with K04 turbo upgrades, making it an ideal choice for stock or modified 2.0T builds.
