Wouldn't mind a better explanation of that myself.

I'm sure it's the number of cells per [insert area measurement here]. Would definitely like to know what that measurement is... square inch?

If that's the case, wouldnt more cells be bad due to more restriction?

This has a good explanation:

Sylenze,
I really appreciate you for posting our Group Buy Thread.
I should have posted the link... :shakes head::shakes head:
Thank you again

Ahhhh....memories! ;-)

AAM HFC and True Dual Exhaust! But sounds great! ;-) Here's a new vid:

NICE!!!! :happydance::happydance::happydance:
I was waiting for you to go 1st, 2nd, 3rd WOT LMAO

Thank you Toohip for posting our AAM Comp 2.5" TD CBE and AAM Comp HFC!!!

I just got in from doing a new launch and drive by. Uploading now. ;-)

I just hope that the Berk High Flow Cats make just as good a noise with the AAM exhaust as the AAM HFCS cause I have Berk's HFCs and they provide more power and torque so I'm keeping them, but I really love the sound of the combo of the exhaust and hfc on toohip's youtube videos...Best sounding Z ever!!!!

I got mine after hearing toohip's and its just what I wanted.

Aam hfc
 

I am scheduled to get the AAM HFCs installed on my 370. Do any of you guys have these same high flow cats? If so, have you had any problems with the "check engline light" coming on? I'd really like to know before getting them installed on my z and risking having to reset to ECU or whatever I'd have to do to fix that ****

I had berk hfc, was tuned and still had lean engine light codes come after a few months. No big deal. It can happen still.
