i have an 06 g35x.. currently i have an hks sport axle back.. in a few days ill get a 370/g37 HR y pipe at my door step... now i am shopping for some Berk HFCs.. my question is do i get the 03-06 HFC, or since i have the 370/g37 Y pipe i should get the 07+,g37,370z hfc... can anyone enlighten me?

Pretty sure it doesn't matter. If the Y pipe lines up with everything than the HFCs will line up with the already lined up Y pipe. No?

get hfc for your car year.
Ypipe is just an oem replacment doesnt change the alignment of the hfc.

I could see how he got confused. If you over think the problem, it causes confusion..lol

You guys talkin' about me?

I just read what I said and it confused me. But it makes sense... ya'know?

ref. OP

Ok, good.

Anyone know if these will get you any power with a tune?

I have the 350z HR ypipe...


dynoed by a member here and gained 6whp with it, but only one dyno test has been posted

search around its posted

Oh, that's not bad at all.

I'll do a search!

Ace, I'm the one who sold u the Y pipe.. Its pretty much brand new so you lucked out..

As long as you run normal DE headers you can use 03-06 sedan exhaust components or 03-07 coupe components.. However if you get HR OEM or aftermarket headers, you'll need HR cats/components.

Alright thats what i figured.. just clearing things up.. thanks guys... ordered my berk HFC today =)... officerdbag lemmie know when you get the tracking number

Just out of curiosity and I'm sure ace wouldn't mind know. Can the HFC and Y pipe install be done on ramps? I know I need new gaskets but can I avoid the shop for this one?

I think alot of people change their exhaust by themselves you just need to gaskets. Unless your shiit is all rusted down there then you would need to torch the bolts.

you wouldnt even really need ramps. changing a y pipe is VERY easy. Re use your old gaskets unless they're totally ****ed.
