Are dynomax super turbo mufflers worth the cost?

I like Magnaflow straight through mufflers. I have the 18" oval case (total length 24") It quieted down my 440 but still roars when you get on it. Doesn't have the tinny sound or drone like the flowmaster.

I've had alot of experience with magnaflow and straight through packed mufflers and I feel like they are a little 'boomy' for my tastes.
