A car owner who is trying to give more horsepower to his car would have to remove all the restrictions if the exhaust. You have to let the exhaust gases to flow smoother out of the vehicle. Because catalytic converters are very restrictive, many people opt for straight pipes for their cars and trucks. They eliminate the catalytic converters totally. Depending on the State you live in, this could be illegal but if you are using the car for performance or only for drag racing and not for everyday purposes, then it should not be an issue.
Using brown gas as fuel is even better than H2. This is the most appropriate type of fuels, and should be the only choice for propelling the vehicles. The gas is made out of water, so the main elements are O2 and H2. The gas burns in the internal combustion engine and gives away O2 in to environment. The final product of this reaction is water in form of steam and O2. It is the same as that of the fuel cells. This O2 is also a part of the water used in manufacturing the brown gas. This O2 coming out of every vehicle will enhance the O2 level in the atmosphere.
It is not absolutely required, but it is a good idea. The factory by-pass valve is prone to failure, and an aftermarket BOV is probably a wise investment for preventing turbo damaging compressor surge. And it sounds cool too. However, it must be noted that if you still have the factory mass-air flow sensor, a blow-off valve, which is vented to the atmosphere, may cause stumbling between shifts.
Get the replacement tubing that will be placed where the catalytic converter recycling used to be and then mark the tubing using a permanent marker to cut the right length. Again, using the reciprocating saw cut the new tubing at the desired length.
Most people are unwilling to lift the hood of their vehicle and get their hands dirty replacing or cleaning parts. Instead, they rely on their local mechanic. The irony is that a little automotive knowledge and a few tools is enough to replace hoses, plugs, and simple components without the help of a technician. It’s also far less expensive.
There are a host of new “clean diesel” cars hitting the market you might want to take a look at. The miles per gallon figures are staggering. How about the Volkswagen TDI Golf that gets 42 mpg in the city and 49 on freeways? How about the 35 mpg BMW 335D? These are just a few of the diesel vehicles coming onto the market as a non-hybrid method for dealing with high fuel costs. To increase performance, each is fuel injected and highly tuned.
Another problem could be the alternator. This is probably the most delicate and important devices in your car. The alternator accounts for charging battery as the car is running, therefore if the alternator bearings can be harmful, the engine will have to make up for the “lost” energy, thus exhausting it. The only possible fix here is having it replaced and keep in mind that it isn’t the type of job that you can do yourself in the garage. You’d better go ahead and take car to a certified mechanic in order to have it properly replaced.
