Altering the stock system may void the warranty + it's not a race car… Leave it OEM

The perfect exhaust is the one that comes from the factory. If you put an after-market system on your car it will probably void the warranty on the car, which would be foolish.

Go to a muffler/exhaust dealer where you live, maybe timbuctoo.

It will void a a warranty, as they know you are abusing the car. Gee, I shoulda bought a V8.

Get standard equipment so that you do not attract the attention of the police (and get tickets).

I'm sorry, but it's a Honda Accord Sport, not a race car. Or even considered a tuner car. That's like giving a Toyota Camry a body kit.

Almost anything you do to the exhaust will reduce your power & drivability. The factory engineers have spent a LOT of time & money optimising the complete car breathing system for best power, economy, noise etc. Almost anything else will adversely effect this. Most aftermarket systems add power at the top end (at the sacrifice of mid range drivability, economy & reliability) Now ask yourself what percentage of your driving will be at max revs full throttle?
Older cars built prior to 1990 (about) work could bedone t oimprove performance with te breathing but modern engines all that is done already (that's why bhp/l is now much higher tha nit was 30 years ago

Good luck finding a place that will consider doing something so stupid.
