OEM exhaust mod shootout needed

Wondering if anyone possiblely could or has put together a comparison of the two different methods of OEM exhaust mods

The ACM "straight pipes" method v. the original "cover the perforation" mod.

Would love to hear the difference in tone and loudness as they are pretty different mods but both sound great. Maybe ACM could put something together to compared as they could always convert the original type into their mod since they block the middle section off anyway.

Could do a comparo with a car with covered perforations and their mod, then just turn the comparo mod into the ACM mod to sell. That would be awesome!
