Does it make a nice difference in sound? Is it worth the time to chop off the cats? I really think it would let out the full potential of the magnaflow. Do you have a video of it by chance?
I don't understand, would there be fueling issues? On my motorcycle with the cat removed and just a muffler, it runs better than ever. So wouldn't that theory of no cat with a muffler be the same as with my truck?
I got a 22" Magnaflow on my 6.0, and I think it would really sound mean if I remove the catalytic converters. Has anybody done this? How hard is it to do? Any tips?
