Default cats

I dont use cats right now. But im planning to rebuild my exhaust system this winter. I use dual 3" from the headers.
I looked in to these products, what do you think?

http://flowmonster.com/mm5/merchant....y_Code=CERMAIC

http://www.afabcorp.com/AFCO_Dynatec..._Code=Cat-conv

Will Ceramic Catalytic Converters do, or must I use mettalic ones?

Se sign for engine combo.

Thanks

I'm running the Dynatech PoweCats. A very high quality cat at a decent price.

Or if you are going to get the Flowmonsters, get the mettalic substrates. http://flowmonster.com/mm5/merchant...._Code=metallic

Is there any room to even mount those after headers?
Theres not alot of room down there to mount them if im thinking right...
especially with headers.

I could be wrong,just wanted to bring this up.Sorry I cant recommend a clamp or design other than welding to prevent exhaust leaks and rust.

Can someone give me their email addresses, can't seem to find them?? Calling them from Germany is quite expensive.
I would like to know from both companies, Flowmonster and Dynatech how many cells per inch their met. cats have. Would like to get some with 100 cells as they flow the most!!
