exhaust problems on 2001 Honda CR-V

my car is very very loud and it uses a lot of gas and you can smell gas really bad and when I accelerate you can smell oil burning and it at times sounds like popcorn popping and it also shifts very hard... I am a girl that has no clue about cars what do you think is wrong and what kinda price am I looking at ?

It sounds like you have exhaust issue, without actually seeing the car, it is difficult to diagnose
Best to take the car to an exhaust shop as there might be a break in the exhaust somewhere, possibly before the catalytic converter and 02 sensor
