toyota solara 2001

the car is very loud, because someone took the muffler off for a sports car affect. check engine light has been on and I have gotten it checked 3 times but I was told nothing is wrong with my brakes and their may be something I can do for to get that fixed. The air conditioning works best on the highest level but barely on any other ones. Other than those things I have still been driving the car to every destination. It is also still good on gas.
