The V4 is about the same.
Yes it can get loud under WOT at higher RPM, but that is what pass through mufflers sound like.
Also, that lack of resistance is needed to get that 10 hp top.
At partial throttle and lower RPMs, the sound is not too loud based upon feedback.
We do push for turn down tips as concrete and asphalt absorb some quite well and noticeably reduce the sound.
We can try a larger oval muffler that will knock off a few dbs, but it will heavier and add about $100 cost.
Thank you for the great question.

Looks like the engine does not need that much scavenging after 3000 rpm. This video proves that a 3-inch exhaust system is better than a 2.5-inch one.

For built S2000 NA motors making over 300 hp, 3" is probably better.
For stock bottom end, making well under 300 hp, 2.5" is better.
This V8 is 600+ HP or over 300 hp per bank.
