ok i have exhaust drone like no other and i cant find out why. i have a new cat-back and it does have a resonator and i have pacesetter headers. on my old exhaust set up it didn't have any drone at all and it is the same resonator is there anything else that will cause this?

Exhaust leak?
Did you change the mufflers at all?

After I took out my res and put in a 28" GP with ZZP 3" DP you could barely tell there was a difference.
I replaced the stock mufflers with Dynomax Turbos and it immediately deepend the tone and made it a little louder. Quite a bit of drone in the cabin after but I don't mind it.
That might be it.

Get a cat...that'll get rid of it for sure...IMO I've heard ZZP Catback's suck so idk.
