Every driver dreads having to one day replace the parts under the hood of his or her car. That’s understandable. Replacing the fuel pump, catalytic converter, alternator, or head gasket (among other components) promises a hefty repair bill. However, the “part” that usually receives the least amount of attention is the one that has the most immediate effect on your safety: your tires. If your treads are severely worn, they can contribute to a traffic accident.
Most wheels today have wear indicators that make it easy to identify when they need to be replaced. If you’re unable to see indicator bars, you can buy a tread-depth gauge for a few dollars at any auto supply store. Simply stick the gauge into each of your tires’ grooves every three or four weeks. Once they wear down to 2/32 of an inch, it’s time to replace them. If you drive in inclement weather, you might consider replacing them when they reach 4/32 of an inch.
Now consider the gases leaving the several cylinders of a cars engine. They need to get together into a single pipe which will take them to the scrap catalytic converter price guide. For this there is a device called an exhaust header which does this job. And this is where matters can be improved by opting for an aftermarket exhaust header. The good exhaust headers manage the gases better so that the gases are sequentially led into the single pipe instead of them all reaching the start of the single pipe at the same time. It also has smooth bends so that the exhaust gases are not slowed down while going through a bend in the piping. By doing this the gases are able to make a quick exit and the back pressure is reduced. You will feel this as your car’s engine being able to deliver power with lesser effort.
If there’s a market, there’ll be a supplier. The average American consumer believed what they wanted to, that the price of fuel would always be low. Compared to the rest of the world, we’ve been paying pennies per gallon when others have been paying dollars. We’re catching up to reality and the rest of the world. American auto manufacturers are experiencing hard times, hard times that have been brought on by short-term thinking and lack of foresight. The rest of the world has been driving small, economy cars for a long time and it’s going to take the American auto manufacturer, and the average American consumer, a long to catch up. Let me state again, that if there’s a market, there’ll be a supplier.
Direct injection – A quicker, more efficient way of getting fuel into the engine. Direct injection process removes the step of mixing the fuel with air prior to injection.
Test the acceleration. Try to accelerate quickly from a stop, a couple hundred feet is more than enough distance for this test. It should accelerate nicely, if not, you are looking at some adjustments or repairs. If it sputters and dies – this is not a good sign. It could be simple, it could be a big problem. Have a mechanic look at it before you buy if you just gotta have THIS car.
The best cat-back systems are made with stainless steel and have a lifetime warranty. In this category you can find systems with less restrictive mufflers. These mufflers will regain some lost horsepower that the stock muffler took, because of its internal design and the backpressure it developed. Some are called “glasspacks” and others are “straight through” designs. You can also find systems that lower the sound frequency and give you a deep sound that is not normally found on the typical four or six cylinder engine. And of course you can find systems that have a giant tail pipe tip. It looks impressive, but for practical terms does not do much for your car.
