Drone fix for Flomaster HP@ on 3.5l?

Newbie here, anyone have a fix for hte drone on a 2019 3.5l Tacoma with a Flowmaster HP2 exhaust? I heard about dynamatting but have no ideas what that is... Thanks.

 

Dynamat is sound dampening material.

 

Either sound proof the cab or change the muffler. Really the only options.

 

I have the Flowmaster American Thunder cat back dual outlet on mine in addition to the URD cat delete Y pipe. To say the least the drone was horrendous. I installed one of these in front of the muffler and it made a world of difference. Most exhaust shops should carry them,you will want the 18" X 2 1/2" spiral louvered make sure that the flow goes into the louveres and not over,inlet side is shown

 

What is that like a resonator or something?

 

glasspack used as a resonator FWIW I worked at a Meineke shop for several years and learned quite a few tricks

 

It adds resistance to the flow, to reduce drone, after your change your exhaust to decrease resistance.



It all seems pretty pointless to me.

 

V8

 

If you don't mind a little fabrication, adding on a helmholtz resonator is the way to go.

 

Ditch it for a TRD.
