In one of my other posts, there is this reference:

Invidia - 100 cell
Berk, ERZ, Stillen (I think) - 200 cell
Kinetics (i think) - 250 cell
FI, Exoticspeed (very pretty) - 300 cell

Silly question perhaps, but what on earth does a cell mean?

 

good question

The less Cells = The louder + more gains.

 

Thanks, so for best gains the Invidia in this example would be best, however it would also be the loudest? The Berk which from what I see is the HFC of choice which produces a strong gain while not the loudest of what is available. Is that correct?

 

It wont be that "loud".. its just like 5-10% louder than the higher cell HFC

Yeah Berk is not the loudest of what's available..

Go with Invidia. Its the cheapest and have the highest gains.

 

+1 Cool, thanks JimmiesG

 

Invidia are far from being the cheapest HFCs. lol

 

From Technical

"With its honeycomb construction, a monolith substrate consists of a number of relatively small “tubes” or cells through which exhaust gasses pass. The size of the cells and their length determines the amount of restriction and to some degree, the extent of catalyzing action.

...

Over the years, various brick densities have been used, with the most common now being 300 and 400 cells per square inch. All other dimensions being equal, converters with 100- or 200-cell densities offer improved air flow capacity, but reduced emissions control efficiency. In many cases, it's necessary to significantly lengthen a 100 cell converter to achieve the necessary levels of pollutant control. That additional length reduces flow capacity, so it's possible to end up with a 100-cell converter that does not flow as well as a 300-cell model."

 

lower cell count usually means: more flow, higher hp gain, louder / more rasp, harder to pass smog, easier to trip CEL . . .

 

Test pipes FTW! 0 cel

 

I think cells refer to the honeycomb structure.
