I have and they are bit noisy. But, this noise sounds like a marble inside the engine. But, only when it gets hot. Thats whats messed up about it. Why heat makes this noise pop out more. Ive seen videos of guides making this sort of noise, but how could it be perfectly quiet when its cool or when I drive under 30. Maybe I have gremlin inside the engine lol. Ive asked so many times and it seems like nobody else has this similar issue on this planet.
