As for the last exhaust upgrade, that's just there because the Sagaris' 1480 rank can be changed to 1486 (which is what I use) without affecting matchmaking too much.

Given that most Camaro SS users race at the 1487 rank, I don't see why it's a bad idea to get as close to that rank as possible.

You are getting matched against the same players, except that you are slightly faster and have slightly better acceleration.
