I've recently gotten Borla ProXS 40357 mufflers installed and I love the sound but it does drone and it takes away from the enjoyment of having them. I've heard J-pipes or Helmholtz resonators help reduce drone. Do the J-pipes made for our cars (ATLP, XLR8, RV6) help with this? Thanks all!

Also, I know I've been blowing up this forum with questions in the last week so sorry!

Adding an aftermarket jpipe wont help the drone. If anything adding a jpipe, especially a catless jpipe would likely add to the drone.

You need to add a resonator to reduce the drone.

Thank you for the clear up. I had asked this on reddit and someone told me that a J-pipe would help. He also said "aka Helmholtz Resonator" so I was a bit confused. Come to find out that what he meant was a "J-pipe resonator" which was just that, a resonator. Strange choice of terminology to whoever decided to call that lol.

Get you the Long MBRP resonator you will be happy.
