Make your Infiniti VQ37HR engine growl! Exhaust systems release more power and torque from the VQ37HR power plant and change the exhaust note.

Dual Exhaust Systems

These are the available dual exhaust systems for the Infiniti G37. Each company has taken a different approach at the exhaust design and here you can compare the features you are looking for, listen to sound clips,and see plenty of pictures to help you decide which is best for you. True dual, means there is 2 exhaust pipes running from the engine all the way to the exhaust exit. Various designs can be included in a true dual system and almost always there is some form of pressure equalization between the two pipes.
