More people than ever are working on their cars at home rather than paying a tow truck to haul them to a nearby repair shop. The fact is, OEM parts can be purchased easily online and shipped directly to your door. If you have a little experience with working under the hood, you can often repair your vehicle in less time for a lower cost.
There are some people, which believe that you should find salvage cars for sale, and after purchasing them, go straight to the scrap yard, or recycling center. I disagree! If you want to learn how to buy and sell junk cars for profit, you had better not believe that either.
When your car is on, many of the parts become extremely hot. If you’re not wary, you can suffer bad burns. It’s worth noting that high temperatures are not limited to your engine and transmission.

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.
