I'm interested in getting some Kinetix high flow cats and can get them at a very low cost of their website. I've been told they are very good and Kinetix told me they are "ceramic" (use a ceramic substrate as opposed to metal) which I seem to remember has not quite as good as flow rate as a metal high flow cat. I've done a lot of searching on this but cannot find an answer. Which high flow cat flows the best, metal or ceramic ones - do they have the same "cell" rating?

I know the main difference between metal cats and ceramic is the noise (metal are noisier) but wasn't sure if one was more effective performance wise or if there is not much difference in it really.

Thanks for any help and info.

 

Make ur choice on cell #s

 

I always hear the Metallic flow better.

I have Berks Metallic Substrate. Not sure what the Cell count is. I would guess 300.

From Berk Technology:
"Metallic substrate offers higher flow and lighter weight"


Metallic On the Left. Ceramic on the Right.

 

Make my choice on cell numbers? Don't follow how that answers my question. Do you know the cell rating of kinetix and berk cats?

 

Make ur choice on cell #s, not on what type of material used. Although I'm not sure if this is the "be all, end all" because it appears that the cells could be different sizes. Despite that, I'm going to conclude that a cat with less cells will flow better because there are larger filter openings, thus letting more air through.

 

Thanks for your replies. Does anyone know what cell rating the Berk cats are?

 

yeah metallic cats have more of a tin can sound when not warmed up.. but from what i've read they flow better and last longer..

i've got almost 20,000 miles on my berk's and I just recently checked them and they look good. I was expecting them to crack by now..

 

u want the best flow right? Think about my response then

 

hmm theres ur answer /thread

 

Thanks for your help guys.

Just had a response back from Kinetix - their cats are 200cpi so should add some nice healthy power
