Anyone Know Where I Can Buy A Hfc?

[=CPV35=]

Hi there, I've searched and searched... Anyone know where I can order a HFC for my 2003 coupe apart from b2auto or conceptz over in the states?

B2auto only stock the berks and conceptz only have kinetix and berk... I want some more choice such as Cnt racing or stillen.

Anyone dealt with any other USA suppliers or local sellers who sell HFCs ??

Thanks

Why do you V guys want every modification to be an off the shelf, brand name, bolt on affair? There are 1000's of fabricators out there that can custom make you decent high flow stainless cat/decat pipes without the high markup and shipping buying from the US brings, and that way it will fit better as LHD designs rarely work well.

After fitting up a Stillen twin stainless system for a customer, I was very disappointed with the quality and the materials. (the flanges were't even stainless, they were mild.) I would think twice about using their HFC's.

OP, surely you haven't tried that hard. Z1 Motorsports would have to be the largest US seller of V35 stuff although they do smash you on shipping for orders under $1k.

Whilst I have a set of Berk HFC's on my car (straight bolt on, no probs and surprisingly a very high quality unit), I do agree with Scott. Wouldn't be difficult for a decent fabricator to make up a nice set of HFC's for you. Could work out cheaper too.

V35's really are an easy car to work on/with. Anyone that tells you otherwise shouldn't be let near a car.

Also agree on that Stillen exhaust. Sounds nice but what a pain in the arse POS to fit.

Hi scotty,

Personally I wanted a brand name cat because most of them claim they do not mess with the sensors so that I will not get a check engine light once installed.

Put it this way if someone could fabricate a pair of cats for me for under let's say $400 (the price of a pair of cnt cats delivered) which won't foul the sensors I would be more than happy to buy from them, until then I'm stuck with looking for brand names from the USA as my old cats are pretty gutted and broken.

Hi iamhe

Personally I've never used z1 before so I might ask them for a quote, I got quoted around 550 delivered for the berks from the other 2 vendors which is out of my budget, that is why I am looking for some other vendors who stock different brands so I could compare.

But if I could find someone who can fabricate a pair of cats for me locally for a better price of course I'd go with them.

[scotty nm35]

For $400 you will get what you pay for. (considering decent cats are $150 each) Good luck with that.

^ Agree.

Just wait a little longer and get some Berk's.

Also interested as to which HFC's give the CEL and why they would do so?

I was told it is because more air is flowing through so it tricks the ecu that something is going wrong. I heard also that the Berks throw a check engine light, is this true in your case?

The CNT racing ones I enquired about have a extended bung for the sensor welded on so I was told they do not throw a check engine light.

[scotty nm35]

Now we come to the crux of the issue. Manufacturers have been installing longer o2 bungs for years to get around the rear temp sensor throwing a code, sometimes it works, sometimes it doesn't. You can trick the sensor directly instead, using a resistor I am fairly sure.

[PN-Mad]

Or by using uprev to disable the fault codes....

[sonicii]

I thought the rear O2 sensor was just a confirmation that the cat is actually working, so as long as you have a working cat, and the rear O2 sensors have been fitted, you shouldn't be getting a CEL.

From memory, the extenders were useful for preventing a CEL if you use test pipes (no cat), as they get the O2 sensor tip out of the exhaust flow and therefore don't correctly detect the exhaust contents.

[scotty nm35]

PN mad's idea would be the best option.

No, not true. I have no CEL. Seems like there is a lot of BS floating around about HFC's....

I would if I had the cash right now, later down the track I will eventually get a tune, but right now I'm just looking to change the cats as they are broken and making a really annoying noise.

On g35driver, it seems some people have CEL on and some people don't with the Berk HFC's....so I was just wondering why was it that some cars threw CEL's and some did not....

Also, I've looking on Z1 motorsports, they are selling Berks for $495, not inc shipping which I guess would be another $100 or so on top, so $595 total, out of my budget.

I'm really looking for the CNT Racing ones, shipped around $400... does anyone use any other US vendors to buy their parts from??

Or does anyone know where I could fabricate a pair of HFC's for under $400 in Melbourne?

Or is anyone selling their stock cats/ aftermarket cats ???

[scotty nm35]

The tight wad option is to punch the cat's out and ignore the light.

I could make them from stainless but like I said, the high flow 100cpsi cats alone are $300, plus getting stainless flanges laser cut. There is no way anyone could do them locally for under $400 unless they cut major corners, as CNT must have done do deliver them for that price.

Tried the wreckers?

[PN-Mad]

Buy a stock set off someone that has modded them?

Being poor and/or having limited funds and modifying cars are generally incompatible.

I would be questioning what other mods have been done and if there were any issues when refitting the sensor or even how it was handled during the upgrade.

I got mine through Concept Z Performance and the cats are very high quality (especially for American parts).

I could probably sell you my stock cats if you want a set. They are roughly ~55,000kms old. PM me if you are interested.

[=CPV35=]

Concept z quoted me 550 delivered and then 600 delivered when I used a different email to get a quote lol.... Pretty dodgy.... If I get the berks I would probably get them from b2auto who quoted me around 500 delivered... However I would still much prefer to get the Cnt racing cats which upon doing some research, seem to be a good quality cat at a good price.

But I've pm'ed you anyway regarding your stock cats...

I installed Berks HFC on my 370gt coupe a couple of weeks back, no CEL, when i got them from the US i was amazed at the quality of materials used (SS) and workmanship in making them, i would absolutely recommend them. They are more expensive than some other brands like kinetix but definitely worth the extra cash!!
