Deleted mine today. Or, Midas did for $75 in 15 minutes.
There is a small bass sound increase that you can hear from the driver's seat, but it is barely noticeable. I was hoping for more based on the videos here I've watched. If you rev it past 4k there is some nice rasp, but revving my engine when it's not moving is not typical behavior for me. When climbing the RPM band there is again a noticeable sound increase, but it is very small and normal people will not notice it. Not loud at all, no drone.
From outside the car it does sound different, but how often am I gonna hear my car from the outside? Actually it sounds similar to when I've had resonators removed on other cars, there is a particular sound it creates, but it is very minor with our small engine. I was hoping for a bit of exhaust noise here without paying hundreds of dollars, and I wish it were a bit louder, but hey half the fun is in the process for me. I might look into a muffler as opposed to a full exhaust, but I want something that's not too loud, and I really like the Ford ST muffler tips. Time to search "muffler".....
Anyhow hope that helps others...if you're on the fence, don't spend your money on this unless you feel like doing it yourself for cheap.
Final thought, it is 105 heat index here and real humid, it will probably be a bit louder in cold weather.
