What does a N63 Downpipe do?

The downpipe on your turbocharged vehicle directs exhaust gases from the turbine housing into the exhaust system. An aftermarket N63 downpipe typically features a larger diameter and may include a high-flow catalytic converter or remove it altogether, improving exhaust flow.

By replacing the restrictive factory downpipe with a high-flow unit, you allow the turbo to expel gases more efficiently, which leads to increased power. With the factory limitations removed, your vehicle can achieve higher boost levels and enhanced performance, as the stock downpipe is often a major restriction in the exhaust flow.
