Tony always looks out for his customers... much respect for that.

I'm all for more affordable products as long as quality isn't sacrificed. But I'm sure Tony isn't the type that would sacrifice quality and performance.

My main reason for not wanting polished test pipes is that the last thing you want to be blinging around SoCal is test pipes. Making it less obvious is my first priority... and the fact that it would be cheaper to not have them polished is just an additional benefit.

IMO, the only thing I want polished under my car is just the mufflers and exhaust tips. Anything else is probably not worth the additional costs (for me).

 

+1 if its only like 50 dollars off then its not even worth it.

I thought the price was high because of R&D

 

^^^ I cant believe you guys would pay $50 for polishing...

I'm certain it was already explained that the cost is due to the craftsmanship... top welds, made in US, etc... all mentioned in Tony's post earlier (I'm too lazy to quote it)... R&D is obviously part of it - and if these were cheaply made in China I'm sure the price would be suitable for those that are complaining... but many (if not most) prefer to pay for quality.

 

What's really the purpose of having polished stainless steel over non-polished stainless steel in applications such as exhaust components (the non-visible parts)?

We should just let Tony do his thing. He's the only one who will decide if its worth to cut some significant costs without sacrificing anything significant. Speculating won't do any good.

 

Hi Guys,

Here's another pre/post dyno!

BASELINE: REVUP 350Z with stock revup plenum, regular test pipes, Shockwave))) dual exhaust and full tune to regular test pipes.

The only variable here is switching out test pipes with ART pipes.






Enough test units have gone out for independent testing for a good ranging sample of dyno results. And everyone who has purchased independent dyno test units have a 100% money back guarantee of satisfaction.

Thank you for participating!

Several independent dynos should be coming in shortly

 

im such a noob when it comes to reading these things..^^ can anyone explain.. i'm interested in getting hfc's, but i have been waiting a while for these to come out....i see peak hp at 16hp and peak tq at 29tq between 2200 and 3200 rpm....? is that peak in addition to what the other tp's were at or..?

sorry.. maybe explaining will help otherz too..

 

^ Thats the way I see it too, but then again, I don't have much experience with dyno graphs lol.

 

^^^ it's looks to me to be a low-end friggen TORQUE MONSTER!!!!! From the way I read it those are the gains over test pipes... that's HUGE!!!

This could be better than shorter final drive!

I really wish I didn't just replace a bad hfc... I might have to swap (Crawford cats might be available soon )

 

Yes. That's exactly what it is.

 

these are the new "true" FI test pipes... FI as in Fvcking Insane!!!! those numbers are incredible

 

Tony, did you post gains over the stock cats?

 

Those really are amazing numbers, and the best part is, those are the rpms I spend most of my time driving in.

Would the gains be similar if it was a non-revup? Also, you clearly point out that the cams are tuned to the regular test pipes. In my case, would it be worth the money to get a re-tune after having these pipes installed?

 

IMO, the test that will reveal the legitimacy of the ART pipes will be 1/4 mile testing under similar DA conditions, same track, same driver, and shift points when compared to test pipes. The gains are huge, but what sticks out in my mind is the fact that the gains are realized in the low rpms and only for around 1000rpms. In a race situation, the only time you're in the 2200-3200rpm range is in 1st gear on the launch. If you've got a 6MT, you should be launching above 3200rpms so these gains wouldn't even apply. After 1st gear, all WOT shifts will land well above 3200rpms. It's hard for me to if say the ART pipes would improve 1/4 mile times over regular test pipes. My guess would no improvement or a very margin improvement. We won't know until someone does a quality 1/4 mile test.

Now around town, the driveability could be improved on initial acceleration and the car may have a bit of a turbo coming into boost, but it may feel odd because the power ramps up and falls off very quickly. I'd love to see what a try dyno plot looks like. My guess is it looks very much like a torque converter going between slip and lock. When that happens, you see massive changes in torque and HP in the lower rpms.

Finally, these parts do make gains and if you're car has OEM cats, the car will be faster. The question is, how much faster will you be with ART pipes compared to regular test pipes?

 

corner exits on a road course or auto cross (or even spirited street) will be a blast!

There's a lot more to performance perspective than 1/4 mile straight - but regardless... if there are no losses in the mid to higher rpm (which according to the chart there isn't anything significant (in fact there are minor gains overall)... then there is no reason this wouldn't help in 1/4 mile too...

Plus - what has been posted so far isn't re-tuned to these pipes... tweaked cam timing could help? (on cars with variable exhaust cams)...

Seems promising to me... and the majority of us do far more spirited street driving than any drag racing... these should add a very fun element!

 

Too bad the baseline run isn't plotted on the graph for comparison. If this is on a "heartbreaker" dyno the tq #'s are for pipes.

What make/type were the "regular pipes"? As you know there's many different pipe diameters and mandrel bends amongst the brands. I'm running FI non-res,it would be interesting to see the dyno plot for those vs these pipes on an otherwise stock test car.
