A catalytic converter is a device that has been mandatory to put on vehicles since 1975. The threat of air pollution is staggering and with it there is not as much of a threat as there used to be. This device is made to help reduce the harmful emissions that come out of the exhaust of your vehicle.
It’s rarely the cost of the parts that sends the bill through the roof. It’s the labor. Mechanics will normally charge between $50 and $80 per hour (and more for specialty cars). The reason for the high hourly rate is due to the cost of maintaining the facility, tools, and paying wages, taxes, and insurance.
Baby steps. Now is the moment you’ve been waiting for. You’ll be able to increase the boost from the stock 0.7bar levels to around 0.8 or 0.9 bar and, providing your gauges and logger are not showing up any big problems, should be feeling a much quicker car. But take things very slowly and don’t assume because you had no problems going to 0.9bar that you can immediately crank up the boost to 1.9 bar as things don’t work like that. Keep things conservative, especially if the car is a daily driver. You should be aiming for zero knock.
Another important task of the exhaust is to clean up all the emissions that may prove harmful to the environment. When the engine burns the fuel, it emits harmful gases like hydrocarbons, nitrogen oxides and carbon monoxide. The exhaust system, with the help of the recycle catalytic converters, cleanses these gases by breaking down the damaging gas compounds. The chemicals present in the catalytic converter act as catalyst. They change the extremely dangerous gas compounds into less destructive ones. In this era of environment conservation, it is almost a criminal offence in some countries not to have a catalytic converter. The converter is very important for the better performance of any exhaust system. Thus if your catalytic converter is not up to the mark, then you need to replace it immediately.
But there are a multitude of upgrades available and knowing what to choose can sometimes be a daunting prospect. I’d like to think I have done pretty well with my car (a mid 11s car in the 1/4 mile and full daily driver) and so wanted to give you my top 10 tips for upgrading your Evo I-III/DSM.
The exhaust manifold is responsible for releasing the gases. This is done through one pipe. The manifold is attached to the cylinder head where the emissions take place. This part can be made from different materials, but most commonly made with cast iron.
It’s better to have your parts checked always to ensure that you get the best maximum run you’ll ever have while on the road. If something goes wrong, have it noted and be checked by a mechanic or best yet, your Honda mechanic.
