They may actually be quieter than your HFC's.

They are significantly quieter than regular test pipes and they cut drone. They also add a very, very deep, but subtle, harmonic to the sound. So deep, its approaching infrasonic.

 

TOny I am an aerospace engineer and totally admire your work, I suspect these might come in handy for S/C setups, looking forward to try them!!

 

Cool, it'd be pretty interesting to see what sound comes out of mixing the low frequencies of these ART pipes and the high frequencies of the shockwave. I'm afraid these are out of my budget at the moment though, lol.

 

whoa. again i am impressed with your work tony.
i can see why it would be hard to slap on a CAT on the test pipe next to that resonator.

hmm.. i applaud that this is made in USA, but considering the TPs are 660$ ... how much would the HFC be with the additional labor and materials....

 

WOW, you are one smart cookie! Shame all of your hard effort gets lost in the cost perspective of others. I think you hit the nail on the head about being a benefitial part for racers and power seekers. The numbers seem to highly suport your claims of extra low end grunt which is great for racers digging out of turns and such.

Is this the same thing you tried to achieve with your newest exhaust configurations as well? Also when can we hear the difference in the sounds as you mentioned.

 

Incredible. Wishlisted.

Tony - I see these are patent pending...are you thinking of applying (or licensing) this design for use in other cars?

 

In for results. I may consider loosing my HFCs and picking these up after I go FI.

 

So if you're determined to not go catless, this would be best paired with a XYZ with cat module?

 

Now accepting donations to dyno test these .

 

ART here I come! Thanks Tony for making this new and exciting product, can't wait to see how they do on my car, will definitely let you know

 

There won't be any cats on this section.

 

Yes.

 

Yes.

In fact, it would be a good test to see standard HFC's on a XYZ tested against the ART pipes with the XYZ cat.

Cost of the two setups will be roughly the same but I know which one will perform better.

 

Fantastic work Tony.

I know its hard to speculate, but in terms of sound, how much of a difference are we talking about compared to resonated test pipes? If this can reduce rasp and drone, yet still see increases in terms of performance... they are in my wishlist

Do you manufacture your parts all in high polished stainless steel? Or do you offer a non-polished stainless steel option? That would probably cut some cost and make it less obvious to a cop that peaks underneath the car.

Kudos to your R&D!

 

Works of art Tony! I bet the TP makers are going "whoa!"
