new exhaust seems to hang very low,is this normal? on 1995 Toyota Camry

had to replace o2 sensor and complete exhaust but rattles a lot and seems like it's hanging down very low not tucked up under the car.The mechanic says that's the way it fits but I am afraid it will get ripped off everytime I go over a bump.

Have another shop take a quick look at it and get their opinion. If the second place thinks it's too low then nicely and politely take it back to the 1st shop and have them fix it.
