The factory TSI turbo outlet pipe (a.k.a. pancake pipe), with its dramatic change in shape, is not optimized for airflow. AWE aims to fix that with a 26% increase in flow rate which increases in turbo response - resulting in more power and a quicker turbo spool. Testing on the AWE Tuning K04 powered Mk5 TSI showed gains of 5.75 crank horsepower and 6.9 crank torque with turbo response time cut down by half a second.
The AWE Tuning TSI Turbo Outlet Pipe features mandrel bent all aluminum construction for unobstructed airflow and a CNC machined aluminum coupler, ensuring a perfect seal with the stock intercooler hose.
The TOP with factory style coupler is compatible with the factory intercooler hoses. The TOP with clamp secured connection is recommended for aftermarket IC upgrades that use a clamp secured hoses, like the AWE Tuning TSI S3 Front Mount Intercooler Hoses.
The smoothest possible flow transition comes with the addition of the AWE Tuning S3 Front Mount Intercooler Hose Kit. The hose kit offers even more air flow and improved turbo response; delivering an even smoother pathway for air by eliminating the factory-style coupler.
