There was someone local to me that had an ARK exhaust and ended up getting the RHFCs but not sure if he actually installed them. I'm very interested in hearing that combo in person.


You an me both

Don't quote me on this but those sway bars should fit as long as you buy the AWD ones
Would Berk HFC fit on my x?
I heard you have to reset ECU when you install new HFC?

You'd have to check with the manufacturer. I run Fast Intentions, but I don't remember if I had to order ones specific to AWD. You also have to reset your ECU, but that can be done using the method in the factory service manual.

Reset ECU? OR just let it learn on its own.

The only ones I know that are diffenenr for the x models are ARK because of the Chmabers. My Z1's and the FI RHFC'S I ahd fit both RWD and AWD

Anybody know of a HFC that retains the stock support brace (My FI cats do not)?

Thanks for correcting me. It's the Idle Air Volume learning that I recommend after installing HFCs. You're correct, the ECU learns on it's own.

So then how do you do that, is it in the manual?

It's in the Engine Control section of the factory service manual.

Z1 does as well, and they are 300 cell cats.

Ah, good catch! Seems they use the same hangers, too.

Good info.

Orly? $392 shipped to NY. Wow!

http://www.z1motorsports.com/g37_370...oducts_id=5405

So in comparing Z1 to FI, and assuming (?) comparable quality, identical cell-count, the addition of the hanging bracket... essentially, I paid a $300 premium for a pair of little resonators, plus another $100 for the customized welding work. And I waited two months for the privilege.

That's an interesting way to look at this.

Water under the bridge, but still... SMH. I can't help but wonder how this would have factored into my decision last year. Exactly a year ago, in fact.

This seems a reasonable place for this pic, which is the customization my mechanic did last week. The pic has been making the rounds, sorry if you guys feel it's posted too much, but really on-topic here:
