Dear all,
I just realize my catalytic converter had been removed by ex-owner and replace by an mid box.
will this reduce my back pressure and lost my torque?
Any alternative I can use to replace the catalytic and dont loss to many back pressure?
My 520i catalytic was locate on the mid not at header.
Thank you alot.
