i just installed a magnaflow hi flow cat 2 weeks ago on my ride i got 4 hp a gain
There are no differences. High flow catalytic converters are not really high flow; the catalytic converters you have on your vehicle are as high flow as you need them to be. A "high" flow converter will either be of a larger diameter, or the inside is made in such a way that there is less restriction to exhaust flow.
Depending on the application there are free flow catalytic converters available. They are not street legal in all states (California for one).
As far as the environment is concerned, yes. Catalytic converters are very important in regulating the amount of pollution your vehicle emits. As far as vehicle performance, removing a catalytic converter could increase horsepower and exhaust flow. Removing the converter can (and does on most) cause the computer to over-correct for the improper oxygen sensor readings. This over-correction usually causes a reduction in power, economy, and running performance. It is also highly illegal.
Yes, changing your catalytic converter can increase the sound of your vehicle's exhaust. This is because aftermarket catalytic converters may have different designs or less restrictive flow characteristics compared to the factory part, which can lead to a louder and more aggressive exhaust note. However, the extent of the change in sound will depend on the specific type of catalytic converter installed and the overall exhaust system configuration.
I do not believe that catalytic converters (as used in exhaust systems) have a heat shield. They are simply porous blocks through which the exhaust gasses flow.
IN a word-YES, the computer monitors flow in and out the engine removing the cat will screw it up.
We have a 1993 Ford Bronco with 2 catalytic converters. Had one of the 2 replaced over a year and a half ago when we failed emissions. We passed with flying colors. So I say, it can be done.
it does but only on the dino there is not a massive gain or feel but converters restict flow engines need to breathe
Catalytic converters clog primarily due to the accumulation of carbon deposits, unburned fuel, and contaminants over time. This can occur from engine issues, such as misfiring, which causes incomplete combustion, or from using low-quality fuel. Additionally, excessive oil consumption or a malfunctioning oxygen sensor can lead to increased buildup. When clogged, catalytic converters can restrict exhaust flow, resulting in reduced engine performance and increased emissions.
To increase horsepower on a 2005 Cadillac CTS, consider upgrading the air intake system for better airflow, installing a performance exhaust system to enhance exhaust flow, and reprogramming the engine's ECU with a performance tune. Additionally, you could replace the factory catalytic converter with a high-flow variant and consider adding a supercharger for significant power gains. Always ensure that modifications comply with local emissions regulations and warranty considerations.
high flow cats are fake. the cats you have on your truck are as high as you need them. you start messing with your catalatic converters you will have a check engine light and all sort of nightmares.
There is no reason to do this. Modern catalytic converters do not restrict your exhaust flow. All you will gain by breaking it out is a check engine light coming on that will never go away. If your check engine light is already on for a catalytic converter problem removing the honeycomb will not fix it.
