Speakin of a High Flow cat, does anyone have one and who makes it?

 

this is the one i got: http://www.exhaustproslinc.com/carunconwita.html

i got the one with the 2.25 inlet/outlet... i also got it with no air/o2 bungs... it's going to need to be modified by a muffler shop... it's going to need to be cut, flanges added and an o2 bung added... i'll keep you updated, i should be doing it within a month. good luck.

The only O2 sim that works with honda OBDII ECU is the following:

The do it your self ones and the others you might find will NOT work. If the simulator does not use RPM and TP sensors as inputs then it will NOT work, and you will still get a CEL.

Also you may or may not need an O2 sim with a high flow cat. Some of the high flow cats flow a little too well, and you can still get a CEL every few days/weeks.

Oh ok, so is Carsound the only company that makes High performance cat's?

 

Random Technology also makes high flow cats. They mare more $$ but they bolt on, the others you will need to weld on.

 

Hey (57STS) do u know where i could find on of those Random Tech. cat's?

 

If i decided to go w/ one of theses Random Technology Cat's will i still be throwing a Code?

 

you shouldn't throw a code with the random tech cats... they are quite expensive... like 200 bucks. they are carb legal though. good luck.

 

I went on there website and i didnt see anything for a 2001 prelude! I saw that they had it for 96-00! Will that still work eventhough have a 2001?

 

can I run a test pipe with OBDI and not trip a code? or will I still need a simulator?

 

97+ prelude are all the same. So yes it will work for you. I don't think OBD1 uses a 2nd o2 sensor like the obd2 have. So there is no need for the O2 sim on older cars. If you want to make sure look for a O2 sensor AFTER your cat, if you don't see one then you will not get a CEL from using a strait pipe (no cat).

I have heard that even with the random tech cat you can sometimes still get the CEL to come on

 

So its not 100% that the CEL will not come on, eventhough i am buying a Random Tech cat. So is there anything out there that will work instead if buying a stock cat from Honda? Does everyone actually have the stock cat on there car's? What do some of you guys have on your car?
p.s. Thanks for all your help fella's, i really do appreciate it

 

I do not see one on the cat or after it... I may be wrong though I didn't give a good look, can somone verify?

 

Oh really?! Is there anyone that has this cat on there car, that could clear this up for us!

 

does anyone know how to reset the ECU on a 5th gen lude? I have taken the ECU out and the light is still coming on!

 

take off one of the connectors to the battery for like 15 mins.

 

Oh ok thanks! Well i went ahead and bought the Random Cat, so we will see how it does Cross my fingers
