I don't get ticking with my gruppe-s header but I get the wooshy thin wall steel piping sound on throttle. A thicker guage metal would solve that. I understand that open flash headers had thicker construction which would help mitigate that sound.

Interestingly a friend with a 14 FRS sold me his header and it had a ticky sound to it when installed. I don't hear anything like that on my 2017.
I wonder if that's more valve lash issue, and it's just valve train noise echoing into the exhaust?
