Yo. My ears are ringing. Yesterday was my first PVT RUN of 2021. Holy shit the ZF exhaust is hella loud! Spending long period of time at high rpm will most definitely make you deaf lol! On some grown man shit, I slapped the N1 back on. So I want y’all’s opinion. Which type of exhaust does your ear drums prefer? Resonator and muffler setup (some call this 2 silencer combo)? Muffler with no resonator? Straight up piping with no resonator and muffler??
