You should notice an increase instead of a loss of power....
What i heard is that catless downpipes should be combined with a engine tune which may explain your problem. Good luck with the hunt for HP & Torque
"... on the smiles-per-mile charts, the 1-series M coupe can't be beat. It is a challenging piece, a triple-X-rated driver's machine for semi-professionals. Its handling balance provides an open invitation to indulge in latent oversteer, and provides an opportunity to separate the men from the boys. It is an absolute hoot on the track and an addictive plaything on your favorite twisty back road. "
