hi flow cats

I don't know what hi flow catalyst to buy!
Rp supercat, SArd, Re amemiya, HJS, HKS, or somthing else?
I don't want to be very loud. what about a cat back?
So many things what is gonna be the best combination?
About the more power?
If i am gonna buy the rp is it ok to add a midle mufler like the other hi flow cats had?
Thank you

HKS Legamax is a very nice balance of what your were looking for from what you posted from ones you were looking at.

1)Sard catalyst is 76mm in and 65mm out with the hks legamax is ok i thing in case legamax is 65mm.

2)Rp supercat is 76mm in and 76mm out with the rev8 catback or rx8store. is ok in case there are 76mm

The first choise is better for my in case there is a midle mufler on the cat.
What about the piping?
the first or the second choise? I need a little backpresure in case my 8 is gonna stay n/a tuned.

What about if i choose the second choise to add a midle mufler on the rp supercat?
Which is gonna give the most performane?

it would be helpful to know where you are..

and to the rest of the posters trying to help. i am pretty sure he is only talking about a cat replacement with a cat.. not a cat back...

i am running a prototype 100 cell cat with a big resonator.. just pasted 5k miles and so far so good..

the rp supercat is a know good product, only one person with the hks i know of..

I am from Europe living in Greece.
I want to install on my car a cat without the cell goes on and to pass the emission tests. in case i want to install and a cat back and in the future a header. so i need on my cat and a middle pipe muffler. the middle muffler is on the piping to be the exhaust more quite is that correct?
