You can drill a hole in anything as long as you have a strong enough drill bit and drill. But why would you want to drill holes in your exhaust? The exhaust piping is there to route exhaust gases away from underneath the car so they don't pool up underneath your car and seep into the cabin and cause a variety of health problems.
It's underneath your car. Off the exhaust pipe.
That's where the exhaust pipe and the muffler is, maybe yours is damaged.
in the catylitic converter (underneath car...connected to your exhaust
Muffler loud noises
You have a loose electrical connection.
The upstream is on the exhaust manifold almost parallel to the windshield, and the downstream is on the exhaust pipe after the catalytic converter, underneath the car.
You car has an exhaust system attached to the engine. The exhaust can get to upwards of 300o and then because of that, water that touches that hot metal turns into steam resulting in the "smoke" you are referring to. This also applies to the engine when wet.
car hitting a steady car
yes (2) one upstream (in exhaust manifold) and one downstream (just before catalytic converter) underneath car (exhaust).
Could be a leak in the manifold, or a hole in the exhaust, and when you stop the car there is no pressure blowing off the fumes, so it floats up into the car.
