  • Replacing cat with bullet

    I am planning on replacing my cat with a bullet muffler and was just wondering what size the y-pipe is. The bullet I have is 2.5" in/out since I have a 2.5" catback. Should I be able to just weld it right up?

    the y-pipe is 3". your gonna need to weld a reducer onto the muffler for it to work

          unfortunately, that will be the only way to do it.
