Introducing : ARK PERFORMANCE Inc RSPEC Hi FLOW CAT 370z/G37
 

Its here. The long awaited ARK HFC's. You may be wondering why the people in this community have been waiting for this. This is because our HFC eliminates the hiss and rasp created by the removal of the OEM Catalytic Converter. We have utilized our very own Core along with the dual chamber.

Thank you

Team ARK

Number 1 thing people will ask... Price :p

We also have Testpipes coming in. It will utilize the same design but without the HFC's. With the testpipe, the Hiss and Rasp is significantly reduced.

Pricing will be up next week!

eh, your pic says MAF sensors...

:iagree: :confused: Shouldn't they be o2 sensors?


Really looking forward to hearing vids of these.

Will the smaller resonation chambers affect the tone at all along with rasp/hiss?

It's a typo on the picture. They're suppose to be 2x 02 sensors the extra bungs are used for a wideband.

The chambers will lessen / alleviate rasp and deepen the exhaust tone.

fixed. I guess we were just as excited to get this up

I wish I had known these were going to be out soon before I bought my HFCs a couple weeks ago. :(

Can't wait to hear what they sound like :tup:

These look awesome, almost wish I could try them but I have LTH's. My cat is at the Y pipe now and it's raspy as hell.

For the love of mercy, PLEASE make those with the pipe extending through the top flange so you can use the OEM ring style gaskets. It's the only way to have a leak free seal and no issues for years to come. Do that, and you just sold a pair! :tup:

Sub'd..

Are these 2.5" from flange to flange??

Very nice!

For those who pre-order, when will the cats be shipped?

If you feel up to the challenge, try wrapping your exhaust in exhaust / header wrap. That completely eliminated all the rasp problems I was having with my Greddy Ti-C. I would start from the Y-pipe and go back to the resonators on the medallian. You don't have to wrap the mufflers as this should be enough to diminish at least 80% rasp. It will also reduce drone as well. Sorry for the thread jack.

Awaiting price and video clips! :)

I've been running my test pipes for 2 years now and still haven't had any leaking issues. They don't use the gaskets, you have to make yourself one with the RTV high temp sealant. If you use the RTV stuff properly you shouldn't have leaks.

Need info very interested

If all good ill take a pair

Going on the car right now. We will be posting up before and after videos by thursday

They look nice. If I had not already had ART pipes I would probably buy these. Now go start working on LTH's with resonance chambers after the merge collector.....that would be awsome.

If it sounds good, no hiss, and at a reasonable price, then you are guaranteed my purchase

Not a lot of room there, they'd prolly have to put them in the Y-Pipe... If that's possible? :confused:

We all need pricing $$$$, hopefully they are at a good price, and reduce rasp and hiss, if yes Im sold

so do you guys plan on posting pricing info any time soon or not?

that sounds realllly good. Hardly changes the tone at all. awesome job.

So what's the deal.....is there a different thread for prices or ???

I will take the test pipe!!! Can't wait! I have been waiting for too long.

I know you have.

Alex

Any power numbers yet?

Need a comparo with the test pipes and GRIP vs just GRIP and also some details of the flange where it mounts to the engine side (does it allow for the factory ring gasket to be used)?

?????????

shipped to 91744,, hahaha.

my mistake LOCAL pickup!

What's the chance at a group buy discount?

Which forum sponsors are carrying these?

Try Jomer @ Fred Bean Nissan

Did this thing fall on its face or something? No sign of prices or dynos?

Currently we are taking pre-orders. The special Pre-order price for R-SPEC HFC is $538,85 + $39 for shipping and Testpipes are $454.35 + $39 for shipping. We are working on the dyno video... so please be patient guys! These are worth the wait!

When do you anticipate shipping these?
