How To Replace The Exhaust Manifold On A Ford F-150

If you’re like me, then your catalytic converter might be on its way out. This is a very common part that needs to be replaced every 5 years or so during the span of an automobile’s life. The most common reasons for replacing your cat are rust and the inability to pass emissions tests during inspection time.

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.

The general consensus is 17-18psi. Some people have taken it higher, but I don’t recommend it if you don’t have the money for a turbo replacement/upgrade.

Cat back or Turbo Back. The most common question from new Evolution owners ask is “should I buy a turbo back or cat back exhaust system”. This is usually a hang up for people new to modifying cars, especially turbo cars. While a turbo back will give you more power, it will also cost more. A turbo back exhaust includes more piping, and sometimes a scrap catalytic converter price guide or test pipe, and down pipe. On average a turbo back will set you back $250 more than a cat back system.

Almost all vehicles have the ability to use this technology. (Diesel vehicles can be run on fuel made from vegetable oil.) There are alternatives for almost every type of vehicle. You can also find these kits online but they are expensive. The guides are also available to show you how to put hardware item together to covert your vehicle yourself.

The first is to canal out the wastes from the process of burning so that the engine is able to continue with the process and as a result performs smoothly. A good exhaust system permits the waste products to get out of the system rapidly. If these waste products get clogged in the engine, then the whole system will choke. it also helps to reduce the noise that is produced in the engine. The waste gases and compounds go out of the engine at very high pressure. If these gases were allowed to escape from the engine directly, then it would generate tremendous amount of noise. So in order to reduce the noise, exhaust systems channels the gases via metal plates and tubes known as muffler. The muffler ensures that the noise is minimized.

O2 levels are controlled by the fuel ratio being correct from the fuel injection. If there is an exhaust leak all the test numbers will be low and incorrect except the high O2 numbers which will void the test. CO has to do with the efficiency of the burn in the engine and also is highly effected by the fuel to air ratio of the engine. CO2 is also an indicator of the engines set up. The HC’s and NOX are by far the largest problem areas. Catalytic converters scrub or clean the majority of the emissions and need to be replaced when they break internally causing a loss in power and no longer clean the air.
