Tony,

Can you post a picture that include the previous and the new design side by side please?

that would be great! is performance the SAME?

In terms of volume, would the new version now be comparable with the volume level of HFCs?

I read that the original pipes were already slightly quieter than HFCs. Was that just a claim and not true in reality?

ART pipes rock - wish I held on to mine but I trialed them and made the review, I will try them again with my current set up.

When are these new version ART pipes going to be available?

its true current installed ART pipes sounds less then any HFC

Performance is identical in the new design.

As for how it sounds compared to HFC's, I've never done that A/B comparison myself but there are several who have and they say its slightly quieter than HFC's with less tendency to rasp and is deeper sounding.

huuurryy up already!! :p

Can't wait to get my hands on these. Hopefully you guys are anticipating the demand correctly.

When can we see pics of the new design and is the cost on the website accurate?


Also, for those with the pipes, any cel issues?

Yes, I'll post pictures of it as soon as they come out of the ceramic coating process.
(I am much happier with the new design.)

And yes, the website is showing the correct list price. This new design costs more to produce but the $485 price will stay for a while.

same HP and TQ gains?!

Yes.

any news on your intake system?

Not yet. I'm putting higher priority on the exhaust right now.

subscribed for an update on availability.

Tony, Any updates on exhaust?

yep... updates on test pipes...summer is coming, i need some stuff to do.

Yup. About to give up.... :-/

hold for it ya'll....its well worth it

Lol, strange how i was just telling my friend that i might give up too!!

I'am not giving up on test pipes for sure but giving up for exhaust

Hi Tony,
It says sold out on the website :eek:
Are there any available to order? i wanted to order this weekend. If not how long until production ready batch? :stirthepot:

Sorry for the delay guys. They should be ready in 2 weeks. There have been all kinds of new tweaks to the design and I have been working with the fabricator coaching them on how to have them properly produced. Its unlike anything produced before.

I am much happier with this new design. I know you will like them. :)

As soon as they are ready I will post pics.

Sounds good. Cant wait. Thanks for update.

I have to say, I'm impressed with the design on the xyz pipe, particualry with the resonated and cat'd versions -- anyone dyno tested any of those yet?

What exactly is the reason behind the cat'ed version of the Y pipe? How would that be worthwhile option?

My guess is, if you have TP's or a LTH, but still want a cat to pass emissions, this is a way to work once back into the mix.

Be curious to see whether a Z would actually pass a tail pipe sniffer with that single cat tho'.

Also, wondering whether it has two bungs for secondary O2's or if they stay with the TP/LTH?

Very curious to hear the xyz with and without the resonator or cat as well as see dynos...

GZ3 has the XYZ with a resonated section.

I have a single 3in HFC piece part I was gonna trial in the Y but have not gotton round to it yet.

Waiting for new ART Pipes to be in stock.

I'm with you on that!

Putting mine back on with the full CBE shortly, should be fun

Im making 309 rwhp with full bolt ons if i change my berk cats for the tonys pipes how much more power and torque will it make

thanks

Z

not less than 315 :D

HFC gives more who but TP will give better torque.

So you will feel ART more responsive and better torque reading but I'm not sure if there will be more then 3-4 whp difference.

This is actually untrue. The only thing you're dealing with here is more or less back pressure which can effect exhaust scavenging if the difference is great enough.

If anything, the TP would give more HP since it will allow the exhaust air to flow at a higher velocity that could be beneficial at high RPM's.

Also, since horsepower is a function of tq, saying one gives more hp and one gives more tq is saying the same thing. It's the rpm that the torque is produced at that determines the effect on your car and how much hp it gives you.

+ 10 tq at 3000 rpm is a gain of 5.7 hp.
+ 10 tq at 7000 rpm is a gain of 13.3 hp.

Very large difference and yet the exact same "tq gain"
Personally, on an engine like this I wouldn't worry about gains at all under ~5000 rpm, as long as power under that rpm didn't suffer greatly.

If you wanted a torquey motor the 5.0 would have been a better option as this motor will never get you anywhere fast if you don't rev it like it's supposed to be.

I actually think the VQ37's linear torque is fantastic and very punchy past 2K RPMs. People complaining about torque didn't live with a VQ35DE like I did in my 350Z. Either that, or they forgot.

maybe instead some of us had lived with something with more torque.. like a gto.. :p

Or boost..... lol miss my boost

The suspense is killing me.
