Dean,
Just a thought, before you smooth out the transition, you might want to call John at SS if you have not already done so and mention what you are doing. Part of the reason our SS exhaust mufflers behave and sounds like they do at idle, at midrange, and at wide open throttle (and cutting the high pitch tone) is specifically due to the design itself. Also, I do have different headers on my ERA.

Seems the results were a bit different for me than others... I noticed better takeoffs, more midrange grunt, and had to go up a few jet sizes on my carb. Way more air coming out, and due to the chambered effect in/out, it actually makes the car more tolerable (less crackle) to the ears when driving at cruising speed, or at least until i open it up. Compliments all the time on how it sounds with this deep growl, raspy sputter and all. Friends call it the "super deep testosterone sound" whenever they hear it coming.
A friend put the same setup on his BossJBL and his sounds amazing too. I can't imagine any other exhaust on my car now
