Aftermarket performance mods such as exhaust systems have made the Infiniti G35 extremely desirable, like its distant cousins (Nissan 350Z and Nissan 350Z).

  1. Application: 2005 G35, Coupe, 6MT, REV up Motor,105K Miles.
    I’m throwing the infamous P0420 ( Cat Efficiency Bank 1 Code)and was looking into my options. I was thinking on a complete Motordyne/Invidia exhaust. No future plans on tuning or going Force Induction. My goal is to get a bolt on system that is as quiet as OEM. I don’t like the Raspy Crackle loud sound. I prefer a more refined sound such as BMW, Porsche, or Mercedes. Please advise me of possible options.
