I have a 09 G37 coupe AWD... Sometimes as with the y pipe, parts aren't the same for RWD and AWD.

Are the berk HFC for the regular non AWD the same for AWD.

So, if i got Berk HFC's for the G37 RWD coupe, will they fit my AWD coupe?

Nowhere could i find them specifically for the AWD but I still see people putting them on their AWD cars.

Is it okay to get these used? or should I be buying new ones? I remember reading somewhere you shouldn't install used HFC's on your car.

 

From what I hear, berk HFC are raspy.

May wanna check out fast intentions resonated HFC.

Also...when you buy used, ya never gonna know what u get.

 

I have Berks and have no rasp anywhere throughout the RPM band, even under WOT. Just depends on what exhaust you have. I had them installed with the stock exhaust and now with the Motordyne E370 and love it.

 

@brainchild do you have the awd coupe? did you use the regular berks if you do?

 

Hfcs should be universal in terms of AWD and RWD because the OEM cats are exactly the same for AWD and RWD.

I got the FI RHFC and they were advertised as "RWD" but fit perfectly.
