mine are at my house in GA and the wife will be sending them to me here in TX ASAP. I will then be checking mine to see how they look. I hope they are good cuz I want them on quick but if they dont look good the I will have to ask for replacements. At the price that they are being offered, as long as it is good quality material and good builds they are IMO, priced to where they should be and what others should be priced at. I agree post the new pics to show the diference and if it looks good the I think ERZ will be getting alot more business. As consumers we must demand fair prices for good products and competition is key to that.

ERZ, if you keep making good products at a fair price you will make tons of money.

edit: And so far you customer service seems to be very good too, another key factor.

Received the replacements today and went ahead and installed them. My buddy bailed on me so I had to do the whole install solo. Went pretty good though. Definitely would have been much easier with a second set of hands. One issue I ran into is that ERZ used some extenders for the O2 bungs. Well they don't have a large enough bore to fit the O2 sensor! I tried to drill it out but only had up to 1/2" bit and it wasn't enough. So I had to install everything without them. I'll see if I get a CEL...

The inlets on these looked much better than the previous set. I'll post the pics up tomorrow and take some video this weekend.

I took it for a spin and all my frustrations of the install and the O2 bung melted away. These things sound awesome and I can definitely feel the bump in power. I couldn't be happier with the performance so far. Only took it for a 20 minute drive but so far so good. I'll update with more driving impressions later on

Have someone drive your car away while you are standing there....sounds sick from outside!!

BTW - I had the same issue with my O2 extended bungs. I proceeded with the install without them. I have put about 400 miles on my car since install and no CEL

I'm a little confused about this part of the install you guys are talking about.

Do you guys mean you are proceeded without threading the O2 sensor in? Some clarification would be awesome!

I'm looking for a more aggressive louder sound than stock...what the best exhaust for that to pair with these HFC?

bluestyle55 · 03-20-2010, 07:56 AM

The O2 extended bung is already welded onto the HFC's but there was also an additional extendor (about 1/2 inch) included. It was a little too big to screw in though I I didnt install it. Not really sure why it was included. But I have put about 1k on my car since the HFC install and no CEL...so it must be fine.

As far as the best CBE...depends on who you ask (everyone reps there own pick). If you want to check out the Invidia Gemini review...here is my thread ( Invidia Gemini CBE & ERZ HFC Review (with db comparison) )

new shipment of 370z HFC and test pipe just came in today.

I had the same issue and I also had to unscrewed the extended 02 bung and install the 02 senors without it. More then 1200 miles with the ERZ HFC and one night at the Drag Strip still NO CEL!

Guys,

I'm planning on getting ERZ HFC for my 2010 G37 and was wondering if you had a picture of 02 bung that you had to modify? Has ERZ fixed the problem with the 02 bungs? The word is spreading on myg37forum...

Thanks,
Wiggy

I had this same issue with the HFC's I received a couple weeks ago. Pretty silly to put O2 extenders that don't fit our O2 sensors.

yep same issue here but I just took them off and put some steel wool in there and no cels to date.

puckshaw · 03-02-2010, 10:45 AM

Good to know if hasn't been an issue so far for anyone.

ERZ, you'll probably want to send out larger ones for the rest of your orders so people don't run into this.
