PROFILE

The ARM AUDI 4.0T Exhaust Fit Kit is the missing link for connecting your ARM 4.0T Midpipe to your A8/S8 rear exhaust section. On some A8's and S8's the midpipes connect further towards the rear of the vehicle, in which case the ARM Fit Kit is required to connect your ARM 4.0T Midpipes to your rear exhaust section.

The precision-engineered tubular design is optimized for maximum exhaust flow, reducing backpressure and enhancing turbo efficiency. This manifold is similar to ones being sold on AliExpress and other overseas markets. However, we've partnered directly with the manufacturer to provide these manifolds in the highest of quality. Unlike those that are drop-shipping similar manifolds from unreliable sources. You are purchasing directly from the source.
