so i was trying to remove my exhaust tips this afternoon and i read somewhere that i just need to loosen the clamp and beat on them with a mallet. I also heard that there may be some welds on the sides? anyway, i got the tip loose and i was able to turn it maybe 45 degrees each direction, so i think i took care of the welds, but i still could not get it off, it was wiggling back and forth, but wouldn't come out. am i missing something?
