If I were in your shoes, before I would spend any time or money fiddling with a new muffler, I would instead delete the secondary cats (as many other folks have also done).

If you know of a buddy who has a welder, your cost is zero dollars - just some wrenching time. And since you reuse your OEM pipes, you are assured of a perfect fit, which is often not the case when aftermarket pipes are tried.

I have made this same recommendation numerous times, and I have never heard of anyone who regrets the work.

This will increase the sound somewhat, which is your stated goal. Then, if it is not quite enough for you, your next step could be a muffler swap.
