Might as well. Couple hundred extra bucks and a couple whp penalty for no smell and minimal, if any rasp. Most of the guys that get the deletes are going to end up spending close to the extra cost of the HFC's getting a resonator installed and then they'll end up losing a couple whp in the end anyway.

jr27

wow. that is a real good way to see it man. but i have never heard the rasp of the pcd's with a rv6 j-pipe. if it isnt too bad i will go for the pcd's v3.

Being in Cali, you should consider the HFC's. I've heard that the cops out there are well trained when it comes to "sniffing out" cars without cats. I'd imagine it's a pretty stout fine for running catless.

spade0698

Richie v6, I just sent you the deposit, let me know when you need the full amount.

jr27

well ive heard of that too but many buddies of mine are running their cars catless and i have not ever heard of anybody getting a fine around here. if you get caught street racing they WILL fully inspect your car and impound it and then make you take everything off.

but believe me that is also a big reason why i never bought the v2. i do often find myself speeding so i guess im running that risk if i do get the v3. i want to see power difference between the 2 and maybe you're right i should maybe go for the hfc.

Hey Richie,

I know you've been busy with the dual exhaust systems, I'm just wondering if the estimated time of completion of the new pre-cats is still the end of January, or if its been pushed back?

Richie v6

ETA is still late Jan early Feb if nothing goes wrong.

were rootin' for you richie!

can't wait to get these installed!

Sonnick

If I had to guess, I'd say these would flow maybe 10-20% better than the V1/V2s. I say this because the flange is MUCH smoother inside. So I wouldn't be surprised to see another 2-4whp from these. Honestly, since the metal is thicker, I could also see the sound of air rushing through go away. With the thicker metal, this shouldn't be a problem.

ANX: Good point about the resonator install. However, if you go with a straight through resonator, you really shouldn't lose any power at all. Maybe 1-2hp. Depending on the resonator though, you are right.

I am excited about these. Slightly more power plus less "air w00shing" noise?

Richie, have you decided what to do on the V1/V2 trade in? Would we get the V3s first, install, then send the V1/V2 back? Or the other way around? Or, send you a larger deposit to get the V3s, then once we ship out the other PCDs, get the money back?

Inaccurate

Good catch Sonnick! You are right. Now that you mention it, I too would think that the ting sound at idle should be greatly reduced/eliminated.

For others reading this - the ting sound of the prior V2 was not a problem. It is just that the ting sound confused many new PCD owners after listening to their car idle for the first time with the PCD. They would wonder where that ting sound was coming from and they would erroneously think that it was an exhaust leak.

All "thin metal tube" headers on all engines have a ting sound at idle. It is the shock wave from the exhaust gas rushing out of the valve and hitting the thin metal tubing and making it ring/ting (just my theory as to the cause). However, the thick casting of the V3 will not ting.

metalball

Richie, I'm finally back from Iraq! Hitting you up on PM for the v3 as previously discussed. However, with your new HFCs starting to roll out, I may be sending more $$ your way than previously anticipated!

Could I get an estimate for the HFC (with their cores, obviously) and the ceramic coating? Is this coating sufficient to contain the heat, negating the need for the heat shields (ie more weight reduction)?

I will be shocked if the hfc produce less power than the pcd... I can bet they will be spot on.. with the hfc producing more low end tq

iTrader: (2)

forget the V3 pcd ill be coming to you with the HFPcds for the install lol

Richie v6

I am curious to hear what they sound like. Once I get this exhaust finished up I will bolt up a set to my car.

I don't have all the details worked out yet. I am thinking are around $120 for the V2 and $190 for the V1 upgrade. I will need some type of deposit or the old parts back first.

I was thinking along these same lines as well. I've only been here three years, so I came toward the end of the whole Procat era, but I know the cars with them were making gains similar to what the PCD's make.

Sonnick

Don't most cars with HFCs (350z/G35/370, etc) make more power with test pipes? Albeit 2hp or so, but still.

Comptechtl2367

I am holding out for the HFC... and the funds to even buy ether!

jr27

wow more low end tq from the hfc would mean better acceleration right? hope this is so like a few here mentioned above because i feel so slow off the line. cant wait to see responses from members getting theirs on.

Get rid of those 20's and you probably will get off of the line quicker.

jnc2000

IMO I'd much rather have the higher torque gains from the HFCs then a few higher HPs at near readline.

^yeah i hope richie can give us some updates as to the major difference in powerband between the pcds and the hfcs

Sonnick

Guys, stillhere chimed in and said he thinks that the HFCs will produce more torque and almost identical power numbers. However, this is speculation. We won't know until they are tested back to back on the same car on the same dyno on the same day.

anx1300c

Dyno will tell. The full deletes may make more torque; who knows.


And yeah, I'd guess most cars will make a little more with full deletes, but not much. What were the V1 and V2 good for on the TL, like 15 whp?

jr27

haha, i know right. lol. but i just couldnt pass up on the deal i got these 20's for and they are actually really lightwieght when compared to the stock set-up, the only bad thing is about 1/2 - 3/4 inch more mass that i have to move off the line due to the larger circumfrence of the 20's. i dont want it for racing but if im gonna buy performance parts i do want it to benefit me the most in the low end. i do ocationally put my stock black painted wheels to mess around though.

richie the install for the HFPCDs is the exact same as the regular pcds correct?

BukvaMan

what would be the ETA for the HFC ??

jr27

+1. can't wait.

Richie v6

Pretty much the high flow cores are thinner then the stock ones.


Same as the PCDs we are just waiting for the castings to be finished. We are looking at early Feb.

Hi flowww precat deletes
my car is crying for them right now lol

Richie v6

RV6 is closed today due to the weather.

When I saw this thread I had to take a peek. It's been awhile since I've done anything to my car. Looks like you may have given me the itch again Richie These HFC sound very interesting. I can't wait to see some dyno results. I think I may be on board for this.

Whats the cell count for the "high flow cats"? will i have a smell if i added this with my non res cat back and 3rd cat delete?
