Audi 2.5 TFSI TTRS and RS3 manifold with Tial turbo flange and MV-R external wastegate, 42.4mm runner diameter and 5-in-1 M8x1 temperature sensor port + DOWNPIPE KIT
GMC Racing exhaust manifolds are created to redefine the limits of engine power and reliability. This is not a simple replacement part, but a state-of-the-art structural component, developed to optimize exhaust gas fluid dynamics and guarantee superior, stable performance that is difficult to replicate with other products on the market.
DESCRIPTION
Conceived and developed by the GMC Racing team of experts, this stainless steel manifold applies the best engineering technologies in the motorsport field. The goal is clear: to combine maximum mechanical resistance with excellent thermal efficiency.
Thanks to the careful study of runner lengths and junctions, our manifold guarantees extremely rapid and linear gas flow, drastically reducing backpressure and turbo-lag. This allows the turbine to reach boost much earlier and work at maximum efficiency.
Entirely manufactured with top-quality materials and high-strength welds, it is structured to withstand extreme thermal stress and sudden pressure variations without suffering deformations or cracks, a problem unfortunately common in budget or stock products. Tested directly on the track in the most demanding championships by our team and our partners, the GMC Racing manifold has demonstrated exceptional durability and clear technical superiority, fully meeting the needs of the most highly tuned engines and the most demanding drivers.
Installation requirements
To take full advantage of the increased gas flow capacity of this manifold, the vehicle requires dedicated electronic calibration (ECU remapping).
