Modifying the exhaust system has certain impacts on the car. Here are the extended details: 1. Currently, most aftermarket parts available in the market are designed to increase exhaust flow. When only modifying the exhaust pipe to increase exhaust flow, the enhanced air expulsion slightly improves air intake, resulting in a noticeable but minor increase in torque output. Additionally, changes in the muffler structure make the exhaust sound louder. 2. The negative effects include a rise in engine temperature. In mild cases, this may lead to slight evaporation of coolant, while in severe cases, it can cause oil evaporation, resulting in minor oil burning and exceeding emission standards.

How long after touch-up painting can polishing be done?

It is generally recommended to wait one week after car touch-up painting before polishing. Purpose of car polishing: Car polishing is a step in the car detailing process where the vehicle is polished before waxing, glazing, or coating. This is because glazing or coating requires prior polishing, and only a finely polished car can achieve a mirror-like finish. This is an essential step for glazing. Effects of not polishing: Unpolished car paint will be uneven, and the glazing will last for a very short time, failing to provide long-term adhesion. In this case, it would be no different from just waxing. Therefore, polishing is usually performed within one week after touch-up painting.

Should You Steer Towards the Wider Side When Reversing into the Garage in Subject Two?

In Subject Two, when reversing into the garage, you should indeed steer towards the wider side. Here are some relevant tips for reversing into the garage in Subject Two: 1. Keep an eye on the rearview mirrors: During the reversing process in Subject Two, always pay close attention to both the left and right rearview mirrors. If you notice one side is wider, slightly steer the wheel in that direction to prevent the other side from crossing the line. Also, remember that when initially finding the right moment to fully turn the wheel, do it decisively without hesitation. 2. Maintain distance: As you fully turn the wheel and reverse, the rear of the car gradually enters the garage. Before fully entering, ensure the wheels are about 30cm away from the garage corner. Students should constantly observe through the rearview mirrors. If the distance is less or more than 30cm, adjustments must be made; otherwise, the car will definitely cross the line after entering the garage.

Does Rain the Next Day After Waxing Have Any Impact?

Rain the next day after waxing has minimal impact on the car. Here are some relevant details about car waxing: 1. Rainwater is acidic: It has a certain corrosive effect, and after the rain dries, many stains will remain on the car, which affects its appearance. These stains are inconvenient to clean for a freshly waxed car. 2. Extend the time between washes: It's best not to wash the car immediately after waxing. First, when the wax has just been applied, it hasn't fully adhered to the surface, so washing the car will definitely have an impact. Secondly, before waxing, the staff at the beauty shop have already cleaned the vehicle once. Additionally, a freshly waxed car body is smoother and, combined with its anti-static properties, is generally more resistant to dirt, allowing for longer intervals between washes.
