Old school we used dual pipes on for each side of the v-motors... now manufactures put dual tail pipes to control back pressure of the higher output smaller motors ... oh and dont forget the converters ...
If your referring to tail pipes, most high performance cars have 4. exhaust pipes? most cars are 1, performance cars have 2.
one, but you can get a double exhaust for it
the cut on the tail pipe has little to no effect on the volume of exhaust. its all about the air flow of the pipes, more airflow equals louder exhaust note.
A cheaper option for dual exhaust without making it a true dual exhaust from the exhaust manifold/headers. Not much performance gained just appearance.
The exhaust manifold is the collection of pipes bolted directly to the engine head. It carries the burnt exhaust fume out of the engine to the catalytic converter and then through the muffler and out the tail pipe.
Exhaust Gas Recirculation. A small amount of exhaust gas is fed back into the cylinder to lower combustion temperatures and lower tail pipe emissions.
The AIR pump, pumps clean air into the burnt exhaust gasses that is in the exhaust system/pipes and cleans it up before it exits the tail pipe.
If you want to find the EGR valve you have to look for metal pipes coming out of the exhaust manifold[s] that don't lead to tail pipe. Then follow those pipes. Can't miss it.
Raise the vehicle safely and start engine with transmission in park and E brake set. Stuff a potatoe in the tail pipe and the leak should show itself.
This water is actually moisture that is liquefying with the aid of your exhuast heat inside the pipes. If you live in a humid area, this water will continually drip from your tail pipes, other wise it will stop after the engine warms up.
The Alfa Romeo 8C comes with a variety of features including quad exhaust pipes, twin circular tail-lights, a carbon fibre and steel spaceframe chassis and a 450bhp 4.7 litre V8 engine.
The tail pipe is part of the exhaust system.
