Hello everyone, I recently did a muffler delete on my Lexus is350 and the drone is killing me. I have searched and found that a resonator can help with the drone. I saw that the Vibrant Bottle resonator (1792) is a cheap way to fix the drone, Do you guys recommend I add a Vibrant bottle style resonator on both sides where the mufflers were? Does it matter where I place the resonators? Also what is the different between straight through mufflers and resonators? they both have a straight through design from what I'm seeing.

No. Just put the muffler back on. The stock resonators (which I am assuming you have) are better than that resonator you talk about.
