What does 200-cell cat mean?
The number of cells in a catalytic converter always refers to the number of cells per square inch. For example, a 100-cell cat has 100 cells per square inch, while a 200-cell cat has 200 per square inch. While a standard cat often contains 400 or more cells, 100 to 200 cells are more generally used in motorsport.
Does a Subaru Impreza have a catalytic converter?
In order to keep your vehicle performing at its best, make sure your Subaru Impreza catalytic converter is functioning at its best. Your catalytic converter for Subaru Impreza is required to convert toxic pollutants into less toxic substances through a redox reaction.
What is a 300 cell catalytic converter?
These 300 cell count catalysts are the highest flowing cats available on the market today and are ideal for use on your turbocharged or supercharged car to encourage quick and effortless release of exhaust gases to keep EGT (Exhaust Gas Temperature) down and head temperatures at a minimum.
Do you need high flow cats with headers?
Headers run better with a tune, but it isn’t necessary.
What is the difference between 100 cell and 200 cell cats?
The 100 Cell will have up to 95% Airflow, is not OBD II compliant and no warranty for OBD II. They have 3 winding centers, therefore they are more durable than the 200 Cell cats. They will give a CEL after 10K miles. They are for racing/track use, but can be used on the street.
Where is the catalytic converter on an Impreza?
The converter is located in the exhaust system between the muffler and the exhaust manifolds. The catalytic converter is easily removed but you need to change it when the car has not been running as it gets extremely hot when the engine is running.
How many catalytic converters does a 2012 Subaru Impreza have?
It has 2 catalytic converters!
Do high flow cats add horsepower?
Adding a high-flow catalytic converter to your car can add horsepower since it does free up the exhaust flow overall. However, it’s usually recommend as final piece to your exhaust system, especially if your car is making at least 20 percent more horsepower.
How much HP does a catalytic converter steel?
The amount of horsepower you will get from a high flow catalytic converter depends on your engine and the modifications you have made to it. You may see a horsepower gain of as little as 5 hp or as much as 60 hp. You may also get an extra 5-60 ft lbs of torque.
Do you need a tune for high flow cat?
No high flow cats do not require a tune. As you are well aware, they will be optimized with a tune.
Can you add high flow cats to long tube headers?
NO. This is because modifying the emissions systems in any way is a violation. Installing long tubes move the cats about 18″ down the exhaust line which is a modification to the emissions system. This is also the reason most LT headers throw a CEL.
What does a 400 cell cat Mean?
A 400 CELL Cat means there are 400 of these cells per square inch. As this number goes down, the amount of physical cells decreases therefore generating fewer constraints for the exhaust flows.
How much difference does a 200-cell cat make?
AWE 200-cell cats were the only mod that made an instant and noticeable difference to the 997S.1 I used to own. I never did back-to-back dynos on my car, but subjectively, there was a big difference starting at just over 4000rpm, peaking at 6000rpm and tailing-off slightly at the very top.
Is a 300 or 400-cell catalytic converter right for You?
A well-engineered 300- or 400-cell converter can be less restrictive while offering far superior emissions conversion rates at the same time. If you’re willing to invest in a high-quality, high efficiency aftermarket catalytic converter, you can free up considerable horsepower while still keeping Al Gore, the Green Party, and the EPA happy.
Do you have a universal 200 cell converter?
We do carry a few universal converter numbers that have a 200 cell substrate but they are like I said, universal. They sometimes require extensive welding and cutting of the original exhaust system, so for many applications these are just not practical. Okay that’s it!!
