Nice! Are you going to install them yourself?

I would.. If I had tools and lift. Already setup appointment at friend's shop. I'll post pics and videos when done.

Yes. Pix and videos please!:tup: I am interested to see how stock nismo CBE + HFC sound like.

i have them as well. id suggest buying some different gaskets and a new set of bolts. the ones supplied were absolutely terrible. otherwise, they've been running great for me at almost 20k miles (i got them on within the first thousand miles hehe). another problem is that you will eventually get a SES light. either buy some o2 extenders (z1 sells a pair) or stuff a thickly rolled ball of steel wool into the o2 bung

Any videos? Dyno's? On my 08 HR I was running Berk TP's and had steel wool in it.. bought it from a guy off my350z.com check engine would come on every couple hundred to thousand miles and go away by itself sometimes for the most part it was good enough. I know these should come with extenders if not I'll get it.. A a new pair of bolts is something I'll definitely look into.

Thanks for headsup!

no videos or dynos, but the tone definitely gets a little deeper. unfortunately you'll also be introduced to rasp (acceleration) and hiss (deceleration). the steel wool trick has worked for me. i used to get the SES light every few hundred miles until i tightly rolled a ball of steel wool and stuffed it in there. i havent had a SES light in almost 20k miles!!! the bolts included are cheap, so i replaced them with higher quality grade 8 bolts.

oh and id say its butt dyno approved as well :)

Sweet man! Thanks alot. I'll be sure to get some steel wool! Rasp and Hiss seem inevitable lol ! However some people with stillen cbe,meister cbe, indivia gemini exhaust combo w. hfc's are saying otherwise and seems for the most part you cannot hear hiss in the video's. Though I want to keep the Nismo exhaust because I wanna keep it somewhat true to it's name lol since I already changed the wheels.

best of luck...

not sure with the TP's, but the HFC's dont have an elbow in the O2 sensor bung. its extended, and the weld looks pretty solid to me. i havent had any issues in 20k miles and i reguarly check as im under the car. YMMV as always

really?! It should have lifetime warranty if I'm not mistaken as long as it was purchased brand new and not via forums. Sorry to hear. Hopefully mine don't turn out that way.

i had to add the CNT branded elbow to rid my car of the CEL.... it didnt help. waste of $70 extra bucks.

^ Try the steel wool stuff it worked pretty good on my 08 HR. ^

ah...yea in that case, sounds like a total waste of money. z1 sells some o2 extenders that work. also...like i said above, the steel wool trick works wonders. the key is to put on a pair of gloves, and roll a tight ball just big enough to fit into the sensor hole!

Is this what you got chops? I'm gonna get it before I go to get HFC's installed this thursday. Let me know thanks!

thats exactly what i bought! just roll it into a nice thick ball. be careful though...id suggest wearing gloves. that **** can get stuck in your hand

i did... kept stuffing steal wool until it would just all burn out. even stuffed it with wool AND added the bung extenders.


crap product if you ask me. i should have not been a cheap-o and bought the GTM ones. oh well back to my factory cats...

like i said above, you have to roll the steel wool into a tightly packed ball just big enough to fit in the bung. the first time i tried steel wool i just packed it in there and it all burnt up after a quick drive around the block. rolled it up into a tightly packed ball and voila...20k miles later and its still there

again, i did............ it would work about 2 weeks then the light would come back on. i tried packing it medium tight and it didnt work. then i tried cramming the sh1t in there so that barely exhaust gas could even get to the sensor. again it worked a few weeks then lights right back on.

in the end im actually happier w the factory cats back on. the smell and hiss were getting on my nerves.

^ Did you have cnt test pipes? or hfc's?

Update: Fedex delivery showing they should be at the shop tomorrow 8/15/2012. Keep you posted!

TP's which prob flow more air causing the wool to come loose and fall out in time.

im just giving you a heads up about the quality of their parts. i hope you have zero issues and it all goes smooth.

also i had to buy all new hardware with mine. and the factory gaskets had to be reused. the studs are welded onto the factory cats.

Thanks man. I hope all goes well too. Do you have any videos or sound clips?

me? no sure dont. best way to explain the sound..... when you let off the gas make a whhhooooooshhhhissssss sound with you mouth. ;)

Cnt's hfc's installed! Perfect bolt on for your nismo!
 

Good News Installed yesterday! Love em! Perfect sound an barely any rasp!

Install went pretty smooth took only about an hr or so tops for both. Stuffed a ball of steel wool grade 3 into extenders as well as o2 bung. No check engine yet drove about 80 miles so far. Sound is deep n throaty! depends on what rpm level you are at, basically it sounds like a stock Nismo except louder and deeper an definitely not annoying. They are perfect so far from what I noticed compared to my 08 HR and its great for daily driving. A+ Highly recommended to everyone looking into HFC's. HP gains are definitely noticable toward mid to higher rpm's and especially at high speeds above 60mph's and throttle response it much better. CNT's seems to have made high quality parts and we also used the bolts/gaskets that came with it my mechanic said they appeared to be pretty good quality and fitment was perfect. Overall pretty impressed with CNT'S HFC'S and I know the sound will only get deeper.

Reasons to buy CNT's HFC's

• Great sound (deeper, throaty)
• Throttle response (increased)
• Much lighter than stock Cat's
• Definitely noticeable HP's gains mid to high rpm's (4,000 rpms +)
• Easy bolt on install with tools and lift!

No smell like TP's!
No check engine! (make sure to put in steel wool into 02 bung's and extenders)

Keep you all posted with video sound clips.

Thanks for looking!

I choose not to comment on your initial post because we didn't feel like we want to get involve with the discussion of whether or not this item is good or bad. Of course coming from ERZ Industries we have to be fair in our comment. Can we say everything that we had manufacture are perfect, NO! There are many things in life that are just simply explainable. For this same HFC we had sold so many of them. Once in a while for some strange reason we would get a customer who's some what unsatisfied with the product for any reason.

We usually like to allow the product to speak for themselves and we are very please to know that you are happy with the HFC. Just keep in mind, and the same goes to anyone out there who had purchased any of the CNT Racing products, our company do offer a one year limited warranty for manufacture defect. If you come across with any issue, feel free to contact us.

Thank you

Thank you for having confidence in our products. Looking forward to hear the video.

Thankyou

Crazy with no muffler.. In Cali you would get pulled over all the freaking time! They would force you to get a smog...

Yup! ^ That sux in cali! Either way I love it.. I'll get some better videos later!

Yes sir!! Cali has the craziest laws! No side tint, Almost no Mods, front licence plate! I am sure there are more!!

I will never put the front licence plate on. I had a Highway patrol officer who is in my jiujitsu class said he would never put his on either if he has one.
I have tinted windows.. and i am getting Test Pipes!! I dont care!! screw them..
I will keep the stock and switch if needed.

^ Yea I've gotten front plate/tints ticket this summer. I have 15% all around and possible looking into stillen front plate holder down the road so I don't have to pay for b.s. tickets lol.

Definitely get tp's great first mod..! yea screw em! lol

Yup a car with no muffler will get pull over in Ca really fast.
