High flow cats?

[mugen_ctr]

What are some good options out there for a high flow 100 or 200 cell cat?

Im in need of a 2.5 cat, as im replacing an redoing my whole exhaust system...

I prefer a direct bolt on Cat atm, as im over custom fabbing a cat, as too many exhaust shops do shotty jobs that are local an cant b trusted for now.... an the last 3 visits have done a awful job of it....

Will a Ek9 cat be suffice for a boost application or better off paying for a proper high flow cat, cheers

An are there any significance as far as bolt on application between the JDM, ADM an USDM cats? Ek9 or Ek1 for that matter, cheers

vibrant makes good affordable 100-200 cell cat
if u got flange, i can help u weld

I'm using a Metal cat converter. Happy with it so far. Heard mixed things about Magnaflow but generally more good than bad, and their prices on Ebay are usually quite competitive.

Using a magnaflow 200cpsi metal core cat, got it brand new around $150 mark.

I would choose metal core over ceramic core for longevity, and both are similar in prices.

wouldn't hurt for you to go 200 cell for boosted application, no need for 100 cell.

Ahh thx for that, to b honest doesnt really phase me what type of cat it is, but u do make a good point about longevity, and the 100 cel part, seeming as its not a track/drag car haha

just did my exhaust tonight dude, same thing as i was thinking.. im using the stock ek9 catalyic converter, and im not sure whether to go aftermarket if im running a 2.5'' catback system

[dougie_504]

Yes you should IMO. I think if you're doing an exhaust, header and catback, why hold back the whole system with a restrictive oem cat?

Upgrade while you're at it

[MYEK9]

well said, what would you recommend ??

[dougie_504]

100 cel. Diameter to suit your cat-back

Test pipes are a pretty good cat alternative.

They are NOT an alternative.
