Of course you’ve seen them quasi-race cars with the biggest exhaust systems making the most thundering noises while parking at your lot. For some, this is just way irritating while for others, well, they just have to put up or shut up.
The toxic combustion of the pipe is converted into less toxic gaseous form. Compared to other mufflers, you can find some with high flow capacity. That is why you need to get high flow cat. As a general example, the 3-inch dimension would convert those of 501 CFM. However, certain high performance muffler gives you around 475 CFM at the same pressure when you test it. You can get it for different imported and local vehicles. It means you can put them on any type of car to maximize the airflow.
It will have some effect on power output, but not a lot. Its exact effect on HP is not clear, but it probably costs a few hp at the most, maybe 5-15hp at BPU(TM) power levels.
One of the first side effects of HHO power is the smoother running engine. The added HHO power makes for a leaner more efficient burn. You’ll get added horsepower with less of that explosive heat. You will have a cooler burn due to the hydroxy gas. You’ve just added an 80% efficient fuel to your 16% efficient engine, you’re going to notice a difference. Your system without HHO power would dump unused fuel into your catalytic converter. The catalytic converter recycling was introduced in 1975 and is used to cook unused fuel to improve emissions.
Make sure they have a website! If they don’t even have a website, then they are 99% of the time a small timer. That means they will give you the smallest amount possible.
Always be aware of where you park your van, look for a well lit parking space, ideally in a busy area. Criminals will look for an easy target, if you park in a busy well lit area you may have less chance of becoming a victim.
Another thing to consider would be to but some sort of block heater or other warming device that will slowly bring the engine of the car up to temperature. This enables it to start better and with less effort than if it was started cold. They are simply plugged in overnight and keep the fluids at an operable temperature. In fact it is likely that when you go to have the winter oil change you will be able to have the mechanic install one for you.
