BMW B58 downpipe with Heat Shield F20 F22 F30 F32 G01 G05 G11 G12 G20 G30 G31

Downpipe for BMW with the B58 engine — replaces the factory pipe right after the turbocharger. The larger diameter and smooth bends reduce exhaust restriction, so the turbo spools up faster and the engine responds more eagerly.

The downpipe is wrapped in a Heat Shield: a ribbed stainless steel sheet with ceramic thermal fibre, spot-welded to the pipe. It keeps heat inside the pipe, so exhaust gases flow faster and the exhaust note sounds better.
