A high-performance metal catalyst was brought in from the supplier. I am very impressed that the purification performance is tremendous while the sound is coming out. Thank you for providing the wonderful product.
Thank you very much.
I have recorded a movie up to 7000rpm.
Movie is in the end of this post.
But far higher in the driving scene for sure.
