I also wanted to change trains some time ago. I just want to make a small change and change the exhaust. I found a video of dragonfly's exhaust on Baidu. Mine is the new reiz. There are many videos of dragonfly exhaust on Baidu, and there are also many videos of Reiz modified cars. I learned a lot about modification from them. I am far away, too. I ordered goods from their company. Bought a new set of middle and tail parts of Reiz. I bought it and installed it. All in their original positions. Are in the right place. Easy to install. I found a garage and installed it. The motivation has been significantly improved. Start faster. High-speed turns are also very powerful, especially the sound. It is my favorite deep and powerful sports car sound. It feels good. You can consider their products.
