SuperSoundMaster for Z33 VQ35DE

Layout designed for "Appearance" & "Sound Quality"

To control the exhaust sound, all pipes layout after the engine must be taken into consideration. This exhaust system controls the sound by the inner structure of the silencer and lengths of the exhaust pipes.
The SSM for Z33 VQ35DE has such a unique horn-shaped round layout. Tig-welding and a fully polished finish improve its shiny appearance.

Overcoming a weakness of the Z33 VQ35DE
