Whats your beef with mufflers?
You can try a flowmaster merge on your Y, that might help a little if anything.
I think you gotta deal with loud as **** and raspy if your going to run straight pipes...

Dynamat will work, but it's basically the most overpriced, inefficient sound damper out there....check around on some of the car audio forums (CAF and ECA are two big ones) and research a little on damper. Brown Bread, MMat, Second Skin, lots of different brands out there a lot cheaper and more effective than Dynamat.

Most sound dampener is designed to be installed inside...if you put it on the exterior of the car above the exhaust, it might stay there for a couple minutes. Maybe.
