Catalytic Converters – Saving Money In Calif.

Like many, you probably thought that once you bought your early Evo/DSM that it would be the end of money spent on it. Sure, maintenance would have to be done but the car was pretty quick from the off and you surely wouldn’t want it to go quicker. And then you upgrade one part and you can feel the difference it makes. Your mindset then changes to one of “I’ll just get this one upgrade, and then I’ll be happy with the power/handling” and before you realize it, you’ve spent the GDP of a small country on the car.

Of course there are other car repair diagnostic problems that can trigger the warning light to come on and you need to pay attention to how your car is operating to decide what the best course of action to take is. Does the warning light flash on and off depending on whether you are driving in the city or on the freeway? When the light is on, does the car drive differently?

Power. This is the ultimate goal right, why we buy the exhaust in the first place. In my experience any exhaust from a well known manufacturer is going to make power. How much power will determine on many factors, and is more than we can discus here. In general you can believe the manufacturers claims of power gains.

The factory ECU is programmed to activate a fuel cut if the manifold pressure exceeds 14-15psi. It does this as a safety measure to prevent what the ECU sees as over boosting. The Fuel Cut Eliminator effectively eliminates, or at least raises the cut to a higher pressure. A reprogrammed ECU can also eliminate this function.

You will need to let the car cool down, preferably overnight, in order to access the system. Do not attempt to work on a hot car. You could be exposed to scalding steam, hot metal, or other dangerous conditions.

Now follow the factory exhaust up towards the scrap catalytic converter price guide. You will now need to remove the mid exhaust mounting bracket from the chassis as well using a socket. Make sure you slip the exhaust hangers out of the rubber mounting brushings. Set this piece aside with your head shield as you will be reusing it also.

The stock intercooler does a decent job up till about 17psi on the stock turbos, after that you would probably notice a significant gain, especially in warmer temperatures, with a nice front mount intercooler. However, keep in mind it will block some of the airflow to the radiator, as well as decreasing response slightly.

Obviously, this is an initial guide and I haven’t even started to talk about fuel controllers, blow off valves, standalone engine management systems etc. But hopefully it’s given you a thing or two to think about. Do you have any more tips you’d offer people starting on the road to tuning nirvana?
