Default Resonator delete, how much louder?

I've pretty much scrapped the idea of deleting my cats, I'm pretty sure it'll make my truck sound like a piece of junk. Now I'm thinking about deleting the resonators. Anyone who's done this, how much louder did it make the truck? I'm not worried about drone, just want it a little louder and more aggressive sounding.

Resonator delete was one of the first MODs i've done to my truck. I have the 3rd gen hemi, with both resonators deleted and a Dynomax ultra flow muffler. I love the way it sounds, and i would recommend doing it if youre thinking about it.
you can go to O'Reilly's auto parts and get a tailpipe cutter and remove the one near the back pretty easily, that's what i did. Then take it to a midas or whatever and have them remove the one between the Cats and Muffler. only like $70.

I didn't know there was another resonator between the cats and muffler?

I was curious about the same...I have a 18" Magnaflow on my 2013 Hemi and would like a LITTLE more idle depth/volume mainly...if it's 5% louder across the board that would be fine as well...
I already have some drone but when MDS kicks in I can barely tell the difference in sound...which is what I am MOST concerned with...BUT since I understand that resonators are put in place to remove specific tones...I don't think those same tones would still be present since I don't have the stock muffler...or is that flawed thinking?

I just bought some MBPR 5" black tips to match up to the bumper cut outs better so I think I may have to remove the resonators anyway...

The resonators are meant to work with the stock muffler. Since you have a Magnaflow I would remove them without any hesitation at all. IMO any aftermarket muffler should not need a resonator. The company designed the muffler to sound good by itself.

Yup, if you're putting on 5" tips your resonators are definitely being removed.


OP, I would remove the resonators (no question) and get some 5" tips. By looking at your sig you already have a Flowmaster Super 10 correct?

Actually the installer said no need to remove the resonators (mine is a 2013 so maybe they are positioned a bit differently) and he doubted it would be much difference either way...but I DID end up cutting them off...more sound and depth for sure but this is also from stepping up to 2.5" pipe and 5" tips...

Yes, I have a super 10. I will be removing the resonators for sure. Needs to be louder.

You will notice a bit more sound...honestly though if you want LOUD then I would do LT headers and no cats...or at LEAST high flow cats
