Choosing a Mitsubishi Evo exhaust system can be a hard task. The decision to purchase is a big one due to the amount of hard earned cash you Will have to part with. To help make the decision easier for you let’s look at some of the important things to consider when buying a new evo exhaust. There is no right answer as to which is best, but you should ask your self a few things to decide which is right for you.
EFFICIENCY – There is a lot of thermochemical energy in gasoline, but there is even more energy in water. The DOE has quoted about 40%, 50 it is probably much more than that. Most people are unaware that ‘internal combustion’ is DEFINED as: a thermo-vapor process; as in ‘no liquid in the reaction’; AND most of the gasoline in a standard internal combustion engine, is ACTUALLY CONSUMED cooked and finally broken down) IN THE scrap catalytic converter price guide, which happens AFTER the fuel has been not-so-burnt in the engine. Sadly, this means that most of the fuel we use in this way, is used only to cool down the combustion process, rather than using a cleaner and more efficient means to do so.
This is a bit of a yes and no answer. The stock filter assembly is a flow restriction, and an open element intake would increase potential flow. However, it will also draw in more heated engine compartment air, which can hurt performance. My advice is to either modify the stock filter box, or install a cool air induction box, like the Max Air. An added bonus of the open element filters, is that they allow you to easily hear the primary turbo and by-pass valve.
Consider the eBook and materials run less than $200 total and can provide you fuel savings of up to $10 every time you fill your tank. It would only take about 2-3 months to have the $200 back in your picket again. That means a weekend vacation at the beach.
Exhaust manifolds are usually pretty restrictive to the flow of exhaust gas. So therefore, they waste a lot of power because your pistons have to push on the exhaust gasses pretty hard to get them out.
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.
We bought these kits and installed them and have also spent some of our time reviewing the available products on the internet. We have found people who have installed them and have had success with these kits and also those who do not.
