It is worth noting that when you replace the exhaust, the resonance generated is likely to be too large, causing the car exhaust pipe to sway left and right. At this point, it is also necessary to replace the hard hanging ear rubber (if it is too heavy) to avoid cracking the joint. If you can grasp these principles well, you will definitely enjoy the fun of modifying the exhaust pipe.
In terms of production, it is natural to require some modern equipment, but the low exhaust threshold leads to a variety of exhaust pipe brands, which is normal for consumers to be picky. However, the main focus is on the research and development of universal drums, and the workmanship of the products is secondary. After the product is finalized, it is produced. There are also car enthusiasts in China who have started making their own exhaust, although there are basically no theoretical calculations based on formulas, and they are still in the stage of imitation.
