It looks like no one make high flow cats for the FX. Have any one try using the 370Z or other infiniti high flow cats on the FX. I am looking on doing high flow cats ark exhaust and custom tune.
 
You'll likely need to purchase a set of universal high flow cats (in the desired exhaust diameter) and have a muffler or fabrication shop fit them to your application.
 
did you search at all? I have a thread explaining the entire process, which to buy, and have pictures!

Buy test pipes for a G37, swap the flanges, re-angle, bolt them right in. I used GTM resonated test pipes.

you can also just get a set custom-made.

Had the FX tuned with the test pipes and different muffler and results were good. Should expect 10hp+ after tune from the test pipes.

let me know if you have any other questions
 
I was on the process of searching this site but there is a ton of material plus i am not familiar with the site.
Thanks for the reply and the pic. are the fx 50s have two cat per side or one.
i was thinking the 370Z high flow cat because they use the same frame right.
I live in jersey and the test pipe will not pass inspection.

There are two, and the 370z/g37 would be the same - you'd have to make adjustments to either one to fit the FX50 please look at the links I gave you.

The test pipes will pass inspection as long as there is no CEL present when you get it inspected. Mine has passed with resonated test pipes since I put them in. I get a CEL eveyr now and then but just delete it and don't have a problem.

Jordan, do you remember the part # for the flanges you ordered from vibrant? I have test pipes but need the flanges.
