Does anyone have any data on how well the factory cat back flows? I think when I do headers I am going to leave the factory cat back in place and put a cutout after the y pipe. Anyone out there go this route?

My 6.0 muffler is a dual inlet and i did pacesetters and dual cut outs right before the muffler. I gained .1 seconds and 1 mph in the 1/8th. Not a huge gain for as redneck loud as it gets.Originally Posted by Smoker_98

Thanks! Does it at least sound good? What about adding a straight through bullet of some kind before the cutouts?
