The exhaust pipes are very, very clean, as if they haven't been used, and they are rare and out of the market. If you find them, I bet on the cleanliness of the one I have because I got tired until I found it. In my personal opinion, it's the most beautiful exhaust pipe in terms of shape and sound. And regarding the sound, its sound is beautiful and gives you a feeling of luxury that delights you, and you will notice people's admiration for it. If you add "loobs", you will hear a sound you have never heard before 👌🏻👌🏻👌🏻 ((Remember God, brothers)) Remembering God is a right, even if you don't buy.
