Could anyone identify exhausts in Hot Version Video (in Gallery Section)?

[TigerNSX]

Does anyone know what kinds of exhausts are installed in each car in Hot Version Video in Gallery section? I am especially interested in the ones in the first car (black one), and the last car (another black one) in the introducion right before the race.

Thank you so much.

I think that if you check the science of speed exhaust section a few of them will be there if not all.Example is the GrouppM car is probably using a GrouppM exhaust.

The lightly-modded black one (Phase NSX) has a Phase Hi-performance exhaust, and the Black Gruppe M SC'ed NSX (K&N NSX) has K&N exhaust installed. Hope that answers your Q's.

Thank you so much for your help, guys!! Are Phase exhausts available in the U.S.A? Do you know any exhausts that have the similar sound as Phase and K&N exhausts?

Thank you!!
