I didn't realize how prevalent this was when I performed this mod. I tried the G and J options first but didn't like the sound. I just had my secondary replaced due to the same crack, repaired the heat shield and replaced the melted plug wires. I do love the sound, however so I will keep it this way until the secondary fails again.
