just what the thread says what is the diference between 200 cell cats over 100 cell cats? whats better??

 

I think that 100 cats is the least restrictive (louder) and 200 more restrictive and quieter. I went from a 200 to 100 system and couldn't tell the difference in power or volume

 

I was under the assumption that 100 cell produced more power??

 

100 cells all the way

 

Nomenclature on catalytic converters is as follows. CPSI is the acronymn for cells per square inch. CPSI is the description used worldwide despite the metric system.

So therefore 400CPSI, 300CPSI, 200CPSI, 100CPSI and 0.00 CPSI equate to sqeezing 400 small squares into a 1.0" sqaure all the way down to only 100 square cells per 1.00" square. 0.00 would be a straight pipe or catbypass pipe. Therefore as one goes dwon the scale from 400 cells per inch >>>to>>> 100 CPSI you will be less backpressure and restriction per unit area given the same design criteria an washcoat.

Your last question " What is better" depends on who is asking what is better?

The EPA & Federal Government would say 400 cells is best as it scrubs exhaust the very best and allows the least pollutants and makes the car the most quiet.

For car enthusiats like all of US.........going to 200 or 100 cells or to NO CAT if that is allowed or permitted is the way to go or atleast head in that direction if maximum power and moer sportscar sound is desired.

I hope this cleared things up.

Just say NO to cats!!!

Listen to this man...

 

thanks so basically 200 cells cats clean out the enviroment better ..over 100 cell cats but powerwise does it make a big difference between 200 to 100? i dont hink it does... correct me if i am wrong

 

Does saving 2 1/2 lbs with the "wiper delete" mod make tou go any faster? I guess the answer is, it all adds up.

 

Also weren't a few posters here tripping their CEL's with the 100 cell cats, as opposed to 200 cell units ?

 

not really coz im damn fat

 

I'm sure the "Gut Delete Mod" would go a long way for a bunch of us!

 

The "dessert delete" mod accomplishes the same goal, and you don't need a fancy plug.

maybe the dinner delete mod will help or the salad lunch option too

 

100 cell cats dont cause CEL's.
