No. A catalytic converter wont. If its a rear wheel drive, check your drive shaft. Front Wheel drive, CV Joints. Other than that worn steering. Exhaust wont cause this issue.
Probably both or all four depending on what motor you have are just before and just after the catalytic converter.
catalytic converter and or heat shield
There is only one and it is screwed in to the catalytic converter on the pass side of the engine.

How much does it cost to replace a cv joint on 4 wheel drive
Fuel filter? Air filter? Plugs? Plug wires? Catalytic converter?
Bank 2 is the drivers side of the engine in a Mercury Mountaineer Sensor 2 is in the exhaust after the catalytic converter ( downstream )
Two wheel or Four wheel drive?
That depends on the type of vehical, front wheel drive or rear wheel drive. Rear wheel drive vehical: Removing the transmission is the best way to go. there is less to un-hook from the trans then the motor. Also during reassembly the torque converter has to be placed on the trans and turned twice, you will feel it click into place (go on further) it must be seated before reassembly. Front wheel drive: Sorry i have no experience with front wheel drive.
