FWIW, I have not had thrown any Cells since installing my HFC's several months ago.

And yes, it is definitely worth the effort in every sense of the word. You will love the sound and performance.

Check out this thread, http://www.the370z.com/intake-exhaus...s-reviews.html

Good luck and persevere. :driving:

LOL I was reading this article 8 Things Thieves Love To Steal From Cars and thought of this thread. If we could all park our cars in these areas, we could get our catalytic removed for free! LOL. Just skip to screen 5 to see what I am talking about.

I was able to get the bolts out of my cats using a 14mm impact socket, 1/2" swivel, 15" of 1/2" extension, and a 2' breaker bar. Try to stabilize the long extension with some wood and rubber so more of your torque is focused on the bolt head. I broke the top passenger side bolt off but the drivers side came out in one piece. Hope this might help someone.

Omg that berk HFC is a b*tch to put on...got it on though even though it took me n my brother 4 hrs to put it on. Sounds great though

zae757... Congratulations, enjoy!

...I actually had one thing to add in regards to the Berk HFC. They didn't exactly line up with the aftermarket Injen exhaust I have on my Z. Is this an issue that is common for the Berk HFC?

I did not have any alignment issues as I also have the Berk CBE. Everything fit perfectly.

Not sure about the Injen exhaust. Someone here should have a similar setup to yours and can comment further.

What type of adjustment/modification did you have to make to get it aligned properly?

The cat connecting to the exhaust was different. The cats had a larger hole than the exhaust but I was still able to connect the two...I haven't had any issues thus far but I was just concerned that I may have tried to put different cats that don't belong on my car, on there

that demon bolt... went through 2 extensions and a flex adapter and finally after a lot of pb blaster got it loose with an air compressed wrench. phew..

Just ordered mine today, I can't wait! Does anyone know if this has trouble passing CA smog?

I just finished up installing Z1 HFC's on my Z and I must say it was a lot easier than I anticipated. I snapped the top demon bolt on the drivers side after that it was all down hill. It took me just under two hours and a couple of beers:yum: I believe if you can install an exhaust or intakes, you can do this! Quotes from local performance shops were ridiculous! The exhaust tone got a little bit deeper and just a tad louder. I love it!

damn it I need this, why aren't the pictures showing up : /

So this thread is half useless now without the pics...

I found this video to be helpful when I did it. It's based on a 350Z, but essentially the same process.

just finished getting my oem cats out. what a pain. question. the one stud left in the header, does is stay?
