BMW M140i B58 BCS OVERSIZE 140MM / 5.5 INCH 100 CELL DOWNPIPE / SPORTS CAT

Road legal 100 cell cat is the ideal hardware upgrade when considering a power increase on the 3.0 B58 engine.

The Powervalve downpipe and 100-cell cat will connect to the OEM cat-back system with a minimum of fuss.

With figures in excess of 475 bhp achievable along with suitable hardware..
