I didn’t notice much with the dynomax, honestly. I had to get rid of xx-pipe and go back to a mid muffler (solo cyclone) to get the sound reduction I was looking for.
My axle back is 2 helmholtz resonators only so it got pretty loud.
I have seen great success with the Vibrant resonators personally. That is what most of our customers end up being happy with when they are trying to tone it down a bit. If you have any questions about the Vibrant resonators, feel free to shoot me a message anytime. Have a great Thanksgiving! Lethalperformance.com
thanks guys... I ended installing 2 Vibrant 1794 resonator and I have to say that I am happy with the result... sound level was reduce (is more tolerable) and also the raspiness was reduced at 3k rpm and the cold start is better too (not too loud)... still have raspiness at high rpm but is ok, and of course the sound of the exhaust chance is more deep (IMO it sound way better)
in overall I recommend the vibrant resonator...
I still thinking on installing later in the future a double H pipe...
