I have a magnaflow direct replacement catalatic converter on my truck . what will happen if i remove/cut the honey comb of my cat and weld in a piece of borla straight pipe . is it possible to leave my o2 sensors in place just where they sits one upstream in the y pipe and one behind the honey comb from the cat . will i get troubles like engine codes and will my sound be nicer or will it sound like crap . i have gibson headers,jba y pipe, magnaflow cat ,and borla catback exhaust . will i have more benefits by removing the cat sound wise and drivebality or is it not worthy. i just want to let my truck sound a little meaner i really think the cat is muffling my borla catback . i was wondering if most of the members are driving with cat or without cat on our trucks and does the truck sounds nicer with cat or without cat . thanks
