put the stock exhaust back on, or buy something else that isn't as loud... or loud only when u want it to be..... like the HMF exhaust and quiet core insert

Try repacking the can. That can help.

Try calling Duncan and see if they have a "Quiet Core" available for your pipe.

Try this before spending BIG $$$$ on a whole new exhaust.
