I started from scratch and fabbed up a new 'noise abatement' strategy today.

I cut off the stock tip, and welded on V-band flanges to re-mount it, then made a second 3" extended tip with a 90* turn for each side to re-direct the sound.

Easy to swap, and they can be rotated to change direction for different tracks.

I only bothered with the outboard tips, because that's where the exhaust goes (bypassing the muffler) in 'track mode', when the valve is opened up. Any gasses going through the muffler will be quiet enough that I'm not worried about the inboard tips.

Interestingly, the size of the actual stock exhaust at that point is 2 1/4"... my turnouts are 3".

I may shoot them with a coat of high-temp black paint, but I'll wait to see if they pass sound first.
