Put an afe catback on my 2009 pro 4x thing has way too much drone. Going to get a couple of resonators welded on anyone done this? Wondering how much difference it will make to the in cab drone.

Resonators

I have a friend that has the AFE cat back, and installed to vibrant ultra-quiet resonators right after the cats made a big difference for him, he also put turn down exhaust tip right after the axle. He said that turn down tipped help with the Drone, virtually eliminated it

Ok thanks

I'm probably going to just get regular resonators installed but the vibrants do look like they would do the trick a little pricey though. Everything else is stock I really thought the cats would of toned down any cat back system guess I was wrong.
