200 cell?

dude jump on ebay, you get get a 100CPSI Racing cat for $170.

Look up kenobi. they're pretty f**kn good, with twice the flow of 200CPSI.

[Adnan r33]

yeah but i need a legal one, they same shop offered 100cell one but for cash and no receipt cause its not legal haha..

so $335 with labour for 200 cell is a bad price?

p.s would it be louder/faster then my current cat?

cheers mate

What about something like this: http://cgi.ebay.com.au/3-High-Flow-Cat-BOKKA-Metal-Stainless-Steel-/330513848977?pt=AU_Car_Parts_Accessories&hash=item4cf4291a91

Is says it passes Euro emissions, but im not gonna go out on a limb and say its legal lol.

would a 100cell cat be to loud?loud enough to attract cops?

cause $150 for 100cell cat is good..might just have to wing it and try my luck with the police?

Why would you wing it when you can grab one of these and be done with it?

It is a high flow and epa compliant cat - Is there a specific reason you want one with less flow?

CFM is power cap

CPSI is Cell's

more cell's = more restriction

100 Cell's per square inch, is rated at over 800CFM.

and the cat doesnt really make any difference to sound but mainly to do with the size and shape of the mufflers/resonators

how is 200CPSI less flow than 400CPSI.

and really is a cop going to know how many CPSI are in a cat without physically cutting it apart?

My bad, was thinking CFM - No need to be such an arrogant twat.

im confused with what the other guy said.. cell and cpsi? the link you provided the cat is 400cell correct or?i want a more free flowing cat cause iv been told

free flowing cat(high flowed) = quicker exhaust gases leave the engine = quicker turbo spool?

i might be wrong but yeah?

[pistol-pete]

whatever cat you buy, make sure you go for one that is at least 1" larger diameter than your exhaust to reduce the restriction as much as possible

or alternatively run a decat like a real man

right..so if i have a 3inch turbo back exhaust id need a 4inch high flow cat?

cheers

as much as i know, it does not matter what cell count your catalytic converter has, as long as it has the same emissions or better then what your car was built with.

the cheap ones on ebay are good, BUT, if you want to be safe, buy yourself a proper stainless one with reinforced bars.

if you have a lowered car you will, i guarantee it, sooner or later smash the insides of a cheap ebay one.

the ceramic/platinum insides shatters quite well and when that does happen, youll feel a lot of power loss.

i just bit into the sour apple and spent the extra 150 bucks for a proper one.

or like said, run a decat..... i wanted to, but i dont want to get caught AGAIN by the cops for running a decat.... you can cop a pretty hefty fine....

also, if you run a 3" exhaust, you dont need a 4" cat, 3" in and 3" out is fine, but your centre piece will most likely be 4" or 5" due to the inside comb

what exactly is a decat?do most muffler shops do those??so id need nothing smaller then 4inch cat if my exhaust is 3inch? how do i find out what emissions my car was built with?

[NYTSKY]

Why are you buying a new cat?

If its because your upgrading or the old cat is stuffed, just get the one Blitz linked to.

Going to buy a 500 series

4" inlet 5" body 100cpsi

250 inc delivery anywhere.

ZUT TUT TUT TUT TUT, basically.

[Bronx]

de cat is basically a cat with nothing in it, all the comb is gone, you can buy em from just jap for 80 bucks, but thye are only race legal. get caught on the road and they do a emission test, they will find out. (just letting you know the worst case scenario)

why do you need a 4" inch inlet when your exhaust is only 3" how can you fit a 4" onto a 3"? its an inch bigger.......

You want one with 3in flanges but 4in or more matrix. Since the matrix takes up space you want to get a larger matrix cross section than the pipe diameter so flow isnt badly restricted. All cats have smaller flanges than the matrix size.
