Dynamat alone won't do it. Dynamat just helps stop panel resonance and helps to get rid of some of the squeaks and rattles. Stuff like Luxury Liner, a mass-loaded vinyl sheet with closed cell foam is actually what blocks the noise.
You can totally DIY and save money. Dynamat is too expensive, anyways, so I'd use what I did... it's just as good and a ton cheaper.
But I'd just see if you are ok with the exhaust first... some people's hearing is more sensitive than others.
