Exhaust Hiss - Honest Thought ?!

taylor.zed · 05-18-2016, 01:35 PM

Hey guys!

I had a 350z with OBX resonated test pipes and an HKS rep exhaust. For the money sounded unreal. Sold the car to my brother and bought a 2016 370z. Thought "why not get the same setup" so i did. Install went great. Getting that notorious "hiss" on decel from about 3000-2000rpm. Sounds cheap. Ive seen a ton of soundclips and it seems depending on which application varies how prominent the "hiss" is. I was thinking of starting by going to Stillen HFC seeing as though the resonance is generated from the cats and basically vibrates down into the Y pipe. Can anyone weigh in on their thoughts or provide advice. Not ideal to spend 800$ on HFC but i want this hiss atleast cut in half for noise otherwise ill be forced to re install the stock cats
