Flowmaster FlowFX are actually the only Flowmaster series that has a straight-thru design. A glass-pack design. It doesn't utilize their classic chambered design.

I have it on my 2018 370Z NISMO. It sounds good and it isn't too aggressive. Flowmaster ranks the FlowFX as a moderate sound border-lining towards aggressive. In the cabin, it is a tad bit louder than the stock NISMO muffler and has no droning. On the outside, it is an increase in sound, but nothing like a muffler delete.

The bad thing about glass-pack designs is that the sound absorbing packing that they wrap the straight-thru pipe will eventually burn off and the sound will get increasingly louder. The only concern for me is the interior noise level and if there will be any droning as a result in time.
