I have a friend offering me a cat-back upgrade for my Chevrolet V3500. I understand it's an exhaust upgrade, but I'm not sure why it's called a cat-back exhaust. I hope you can enlighten me.
Technically, a cat-back system is a system complete with all parts running right after the catalytic converter going back—meaning, from the cat con up to the tail pipe. A cat-back exhaust is an entire assembly that you will simply have to install and connect to the catalytic converter in your vehicle (i.e. the catalytic converter is not included; you will be connecting the system to your existing or stock cat con). The cat-back system is usually an upgraded system for those who are looking to improve their driving power and performance but are worried that this might affect the roadworthiness of their ride. By connecting the system to the catalytic converter, it remains legal because of the presence of the latter device.
I accidentally fill my tank with the wrong type of fuel. What do I do? Help!
You will be surprised to know that incorrect fuel filling is more common than you think—it happens to a lot of people. That said, it doesn't make the problem any easier to deal with. This is a serious problem, and you will need to deal with it promptly. The first step is not to drive your vehicle; don't even turn the engine on. If you realized what you have done right after doing the refill and while you are still at the gas station, do not attempt to start your vehicle to drive somewhere and have the problem fixed—you do not want the wrong fuel to circulate in your system further. Instead, ask for help to have your car pushed to the side and have someone remove or siphoned the fuel from the tank. In case you have already driven your vehicle, call a mobile fuel drain unit to have the fuel drained right away. The damage your vehicle might incur will depend on the mileage and age of your ride. You might need to replace filters and other components, but be sure you address the problem right away to prevent further damage.
What's an airflow tailgate? I have a friend offering to sell me one. I haven't seen it yet and I haven't talked to my friend yet, but I'm wondering what it is. What benefits does this tailgate offer that I won't find in other tailgates? Is it a good investment for my Chevrolet V3500?
The primary benefit offered by an airflow tailgate is the reduction of drag in your Chevrolet V3500 truck. Open truck beds are often causes of drag, which reduce vehicle performance. Now, the usual remedy to this problem is the addition of a tonneau cover. However, there are instances when drivers refuse to have a tonneau added because it interferes with access to the bed (especially if you have to frequently get and then place back stuff into the said area. An airflow tailgate is one that is louvered or meshed—the gate is open, so it will allow airflow to pass through and reduce drag in the truck.
