When I got my bike, the mufflers had already been partially cored. How do you partially core a muffler? Well, it's quite simple, and can even be done with the cans still on the bike. My mufflers had actually been taken apart and the back half of the pipe lopped off, etc. But, my friend simply took a die grinder and cut from the outside in about 3 inches and got the same results, so that is the technique I will recommend. To see what was done to mine, you can check out this page for more info, but here is what I recommend: |

Take your die grinder and cut out the little disc surrounding the pipe. Once that falls out, begin to cut the pipe back into the muffler, removing the baffles and packing as it comes loose. You only need to go in about 3 inches or so for the full effect. Also, keep in mind that this isn't a performance mod, only a sound mod. My friend did the die grinder method, but beforehand he put my already modified mufflers on his bike to compare them with stock. He noticed barely any difference- maybe a teeny bit less torque. Then again, the sound is WELL worth it. It is intoxicating to say the least, and totally transforms the whole driving experience. The pic below shows how far in the mufflers are cored (stuff removed/cut back to). To the best of my knowledge, the packing is still down below the line. But, my friend's packing is definitely still below the line the way he did it, and it has the same sound. You really don't need to pull it all out. |

This pic shows how the pipe was cut back beyond the larger outer diameter exit line. The sound can kind of reverberate inside, making it louder. |

Here's some pics I took while disassembling a spare set of mufflers. The first step is to Unbolt the mounting bracket from the cans with an allen wrench. |

Next, put on your safety goggles and use a chisel and hammer to knock the inner muffler away from the outside shell. The best way to do it is by kneeling on the shell while pounding. |
