Hi, i sorta would like some info on installing my new HFCS

i got the Random Tech HFCs and they use the bracket that the oem cats use,
can i reuse those nuts and bolts? i'd prefer to get new ones if possible at an auto store.


also how many studs come off the headers? from what i see, there are 3 bolts holding the cats and the headers together on each side. and only one of the studs come off the header.

the reason i ask, is i want a sufficient amount of bolts and etc.


thanks!

Reuse the stock brackets/bolts for the support bracket.

On the header side you will need to reuse a nut, but use 2 new bolts/nuts. You'll be fine just don't reuse the stock gaskets.

 

I just installed my Berk HFC's and 2 studs came off with each factory cat.
The bracket/brace needed 2 new bolts as the OE ones wont come off.
I reused the metal gaskets at the header as I was told by Berk they are re-useable.
Used 2 new gasket at the HFC outlet.
No leaks so far.

 

wow awesome video

thanks guys

 

Video makes it look deceptively easy.

I just got done. Four hours of pain

 

Those guys are smoking crack saying not to use impact tools. An impact isn't going to damage an o2 sensor unless you're using the impact on the 02 sensor itself. An impact on it's lowest setting will make short work of every rusty and heat cycled bolt on the exhaust. You need the impact to break loose the rust that typically builds on the bolts and nuts. Using a breaker bar on a very resistant bolt will almost always end in disaster. That video is useful, but most everyone working on the G and Z is going to be working on one that has some miles on it therefore corroded bolts/nuts.

 

I didn't need to use anything larger than a 12" 3/8" drive ratchet to bust them loose. PB blaster and CA non corrosive weather helps.

I do think I busted something in my hand when the first one broke loose and I slammed it into the frame. Kinda put a damper on the rest of the job

 

It always feels better having a new part installed knowing you hurt yourself in the process to make your car better =D

 

i used a torch and impact on the rusty old bolts. then a nice 4ft extension bar to get to the header bolts. i got to use a lift thanks to my friends and that definately helped alot. Also he had a pivoting socket wrench that helped out too. something like this:

wow i took you 4 hours?
it took me just under 2 hours. did wish i had some help from a friend, but they would have just gotten in the way in the end.

i did use an impact gun, but only to remove. overall i had fun doing it, unlike my exhaust. didn't end up using that weird joint thing either.

 

^mine took two hours as well, of course i did plenty of research and mainly watched that video a few times to know exactly what i needed.

 

complete agreed. anytime i've done exhaust work its with impacts. pending on how much rust, most cats on cars in salt/rust climates will snap/break/round out because of the corrsion. impact is the best shot you have at it. then of course the torch. The person is probaly working on a 6 month old cali car, which makes things 10 times easier VS a 3 year old chicago car.

 

go to youtube they have a full HFC installation on a 350z this should help.

 

lol someone posted that like 4 months ago
