If that still doesn't fit for you, I'd a get a front pipe with a helmholtz resonator. Nameless Performance makes one. I would advised if you do this, take your car to a GOOD muffler shop and have them make a 2.5" mid pip with a silencer. I say this because I originally put my muffler delete on first and it added a kick in the pants. When I put on the overpipe and front pipe, I feel like I lost some power. After watching a very informative video on exhaust design, I think it added a vacuum pulse that wasn't there before and jacked it all up.

I'm almost 100% sure it's sensory adaptation and you getting used to it, there is no muffler or muffler walls to speak of to get coated in carbon for any sort of sound difference to take place, it's literally just a pipe. If he really wants some less drone , he should take it to a shop and ask them to weld in a resonator in the pipe that runs between the two tips.

I also agree with getting the nameless front pipe with helmholtz resonator, and you might as well get the nameless mid pipe as well because then you'll essentially have a full header-back done, because the nameless front pipe replaces the overpipe as well
