Ok, everyone. Here a couple of cars I've tested one by one to hear which exhaust is more accurate.
I've been as objective as possible and won't suggest which one you should use. This was strictly done just as a study to see which cars sound closer to what they should sound in real life. This will be useful as a guide for those (like me) who want their cars sounding as the engine they have, no mattering if they sound loud or not.
This is first part of my premium garage. Later I'll post the rest as well as the standards.
