Thanks for the info fellas.

Slay that b*tch! I find that you have to sweet talk the bolt a little bit... If that doesn't work, than being verbally abusive can also yeild good results! Nissan bolts really respond to using the F word every other word

Kabestro, I've only seen problems with older z's 09's and 10's. new z's like the 13' should be easier they haven't had time to really seize.

My 12 had problems.

Not only that, it appears two bolts are facing the engine bay in our newer models. The second bolt wasn't as hard to turn, but it is very hard to snake a U joint down there.

To the OP, get a socket extraction kit. That, in the end, saved it for me. Each time rock the socket back and forth applying as much pressure as possible so the teeth dig in. Then VERY SLOWLY start to crank with tons of pressure. It will creak creak creak until eventually it snaps. Also use impact sockets for everything. They are more expensive but they are not as soft and they don't give as much.

Worst bolt ever IMO. Took me around 8 hours. 4 of which were just getting two bolts off.

Ok so another fail with with the demon bolt. I didn't try the torch or dremel because I wanted to try with out and i was running out of day light. The bolt extractors gave me a really good bite on the bolt but the bolt extractor began to get dull and it started slipping.

I think I'm gonna have to give up on this and take it to a muffler shop to work on this bolt.

Here are a couple pics of what I did this afternoon.

You can see the bolt now is pretty stripped.

I took off the pasenger intake to gain more access, didn't do much.

I know some people are unclear about what bolt it is. It can be any of the 3 on each cat. My demon bolt is the top corner, most difficult to access.

Just cut that fcker off haha honestly my hands were all cut to shreds after I got mine off. So were my friend who owned the shop I was in, and my dads haha the demon bolts are evil and destroy hands, tools, and lives lol

Kabestro · 02-28-2013, 09:41 PM

Damn man, I'm already planning how I'm gonna get this off and I still haven't got my HFC

On mine 2 of my 3 bolts on each cat is on the top. All 4 of them had to be broken off. None of them came off clean. I still have yet to dremel them out of my cats lol. Don't take your car to a big name manifold shop, going to have to go to a small muffler shop. Bigger shops cant touch anything emissions related. Especially if your HFC's say "Off-Road Use Only". I have a feeling a cut cat is in your near future unless you drop the motor and torch that bastard out.

AlexRaymond19 · 03-01-2013, 06:02 AM

Could always take your header off and cat in one piece :-P But that is more of a PITA, and time consuming :-P. Actually is it just the passenger side that is giving you problems? Taking the header off that side is cake. Would probably add an hour on to your install time to take it off and put it on

AlexRaymond19 · 03-01-2013, 06:03 AM

That way you could drill the bolt off, or use vice grips and a breaker bar, or even do the torch method a lot easier

shika805 · 03-02-2013, 03:54 PM

I haven't even attempted the driver side yet. I was thinking about taking off the header and accessing it that way.

You don't want to do that, LOL
Your life will be 10 times worse (if we're talking about doing that on the driver's side, passenger side is easy)

SoFloZ · 03-05-2013, 12:04 AM

That Shiz happen to me but I stripped the head and now stuck with the bolt flushed with the flanged prob going to take it to a shop and have them do it

AlexRaymond19 · 03-05-2013, 09:50 AM

Any update?

chknhawk · 03-05-2013, 09:57 AM

On a side note. What exactly Is the HP gains from the headers. I have been briefly looking at some of the header installs and the header look pretty much like stock except they are wrapped and purty. Is there really any NA HP gains or would they header be more useful in a FI setup?

Going to long tubes with a tune, you can generally net 15-25HP depending on the engine, conditions and supporting mods and specific configuration of the headers themselves.

Shorties, basically no gains unless you get the Momentum headers. Those see significant gains, within the realm of the long tubes.
