Hey guys, I have an G37X as my daily and wanted to improve the exhaust sound without going for a full on exhaust. I bought a Tanabe Medallion exhaust and looks amazing but the sound isn't quite there. I'm looking to just get a little more growl without attracting too much attention, does anyone have a suggestion to add to the setup?

 

TopSpeed Y-back is a nice system for the price. Very quite until you hit 4k RPMS. Tanabe + HFC or test pipes I think will also give you the sound you're looking for. Should listen to some clips with that combo.
