Is 90-93 db inside a car too loud?

It didn't occur to me before but recently I wanted to find out if some gearheads on here think that 90-93 db is excessive for a car with an aftermarket exhaust system. I downloaded an app (which of course could or could not be accurate unless its a true db meter) and most average of the vehicles i'm in are within the 80-84db range with stock components. I installed an exhaust system for my car that came with a silencer and with the silener installed car purrs at 82-85 db inside the car, the difference is that it has a smoother low end burble now. Without the silencer, the car is at 90-93db at 70 mph at 3K RPMs. I used to drive an older 93 Ford F250 pickup with a 4" piping and a Flowmaster muffler and am used to hwy drone. I'm 21 now and wondered if 93 db can damage hearing in the long term even though I'm insulated within the car. I have driven the car without the silencer for almost a year and it never bugged me until now, to the point its awkward driving a quiet car. The max i drive daily is 1 hour tops. I know motorcyclists have it worse.

Added (1). I would install a silencer but I'm not sure if my EGT's are affected since my car came originally with 2" factory and I installed a 3" system from the headers all the way out. Car is a 240sx. Would my egts rise even though i expanded the piping but am now restricting it with a silencer insert or am I being to overcautious. Car is equipped with a 2.4L Inline 4.

Hi so inside your ears are small hairs which when loud noise or music gets above a certain level will shear these hairs off. Never to grow again, so you become permanentlydeaf. This fact most young people never want to hear about when loading up a car with huge sound systems let alone the exhaust noise. This has two negative effects higher fuel consumption. The chances of getting a ticket for making too much noise. As well as the car performing badly with reduced top speed and poor acceleration. All to make loads of NOISE.

In a workplace you are required to wear hearing protection if the noise level is over 85db. 93 db is about what my chainsaw is rated at.

As you grow up you realise that a load exhaust is really just annoying, especially if it's that loud at cruising speed on a a long trip.

A decent silence will loose almost no power as long as the system is designed properly, and make you car much more pleasant to ride in. (and safe your hearing)
