Abstract Modified exhaust aftertreatment filters for filtering engine exhaust are provided as are methods of design and manufacturing modified exhaust aftertreatment filters. The modified filters are subject to reduced back pressure and reduced thermal gradients experienced during regeneration as compared to unmodified filters. The modified filters include flow-through channels obtained by unplugging channels which normally are plugged in an unmodified filter.
