ok here what im thinking. cutting off two of my cats and then dumping the exhaust right after the muffler. no turn downs though.

first of all how would this sound on my 5.4. i like loud so that isnt a problem

second which cats do i cutt out the ones closer to the motor or the farther away ones. the closer ones are kinda L shaped. thanks for the help

 

what muffler do you plan on running? be careful cutting cats. make sure you know where the 02 sensors are.
