HIM: Sir,
I can't see your face either.
You must be the 1000th person to ask why not a UFO (Universal Four into One)?
Do you mind if I ask you why a UFO?
My info was up to date, as of a few years ago, so some things may have changed, but here goes anyway.
1) Who designs the Yosh UFO?
2) Who makes it?
3) Was it tested before it went into production?
4) Who designs the Kerker UFO?
5) Who designs the VHR UFO?
Do you know as much about those famous UFOs as you thought? At least you know who designs and tests my X-PIPEtm exhausts: Me. They have to be that much better than the junk UFOs, or no one would give them a second look.
I'm afraid that you won't find many testimonials for the UFOs. For one reason only, they don't work. Even with $400 jet kits. You'll lose 8% at 4,000rpm & gain only 1% at 8,000rpm. What a great deal!
So, how many HP did Yosh promise you?
Thanks, but no thanks. Please buy a UFO.

ME: 1000 people later and you still have no response? You totally avoided my questions. Can you answer the questions or not? You're supposed to be selling me here. You are the one selling something. Have you no sales pitch? With your attitude, if you were a door-to-door salesman you would have starved to death. Instead of trashing everyone else's product, why can't you PLEASE tell me something good about your exhaust?
HIM: Sir,
I have learned from the 1000 people that once they accept the lies and illusion of a UFO, they can not settle for the truth. Therefore, I do us both a favor by sending you back to the UFO netherworld. If honest testimonials from actual people is less desirable than fantasy magazine lies, then I have nothing to offer you, but truth.
If you really want facts, go to www.x-pipe.com and click on Scavenge, how has it failed. After reading that, and understanding it, if you have a real question, and not some braying, ask. Otherwise, please ignore my work and continue living the lie that is UFO.

ME: I'm not partial to any particular header setup. My father's race car has open four inch headers on it that dump right under the cab. It runs beautifully and consistant and has for many years. Every Mustang or Camaro we built in high school had cross or x pipes under it. All I'm asking from you right now is some sort of intellegent answer regarding the mysterious aura surounding your pipes that makes everything else obsolete. If you can't explain to me why and how they work, then I'm going to assume that you are some hack that got stuck with a bunch of back stock somewhere. If you are who you say you are, then why not the successful business? Why your garage sale on ebay?
This is a direct copy-paste from your website. It says nothing intellegent. It even refers to a '4 channel surround sound' ??? WTF is that? It also mentions that it is compatible with super chargers. I specifically remember in your site where these pipes are compared to all different kinds of forced air induction saying that I quote you here, "Turbos & centrifugal chargers boost top end, roots and screw chargers boost bottom end, but only Acoustic Super Charger™ technology offers 3 powerbands." You tell me HOW does this particular x-pipe create more torque and/or horsepower than a turbo AND a charger? You tell me HOW does it make such HP gains throughout the power band. There IS a science to this. it has to do with air, fuel, and how much/how fast you can properly stuff those through a motor. You seem to know absolutely nothing about engines in general, let alone this exhaust. Is there anything you can tell me that would make me believe that you're not a hack?
Learn about the new technology that blows away conventional scavenge technology of the '50s.
Least expensive power adder; supercharge, at a scavenge prices.

HIM: 4into1 Urban Legends
Urban Legend #1:
Headers produce scavenge, thereby increasing exhaust airflow, allowing the engine to burn more air/fuel, and make more power.
The Truth of the matter:
Most headers designed to create scavenge actually slow down exhaust airflow, creating back pressure, which is why longer duration exhaust cams can improve the performance of a header equipped engine. There is only one way to make more horsepower; increase dynamic cylinder pressure.
FACT:
Only dynamic cylinder pressure can create horsepower. Scavenge is defined as a suction or a less than atmospheric pressure.
REASON:
There is no way that a suction can create an increase in dynamic cylinder pressure. Maybe headers do work, in some applications, but scavenge alone can not be credited with creating performance improvements.
Urban Legend #2:
Scavenge removes burned exhaust gases from combustion chambers, to allow more fresh air fuel to be burned, making more horse power. More scavenge is better. In fact, mankind has gone to the moon, but mankind has never, ever, created too much scavenge.
The Truth of the matter:
Everything has diminishing returns. More scavenge may not improve power. It seems illogical to state that more vacuum creates more dynamic cylinder pressure.
FACTS:
Scavenge, created and maintained by a resonant 4into1 header, does not remove burned gases from the combustion chamber of an internal combustion engine. As the combustion mixture is burned during the power stroke, the mixture begins its burn from the sparkplug and continues burning toward the descending piston. When the exhaust valve opens in the latter portions of the piston's descent, the gases nearest the valve, and sparkplug, are the first to leave the chamber, under hundreds or even thousands of pounds per square inch pressure. As the light, hot, energetic combustion product gases pass out of the chamber through the exhaust port, chamber pressure drops as potential energy (cylinder pressure) is converted into kinetic energy (exhaust gas velocity). This high velocity exhaust gas column then tends to stay in motion, even after all of the hot, burned, exhaust gases have left the chamber and the chamber pressure drops to zero. Scavenge is then created as the still rapidly exiting exhaust gas column evacuates the chamber by sucking any unburned air/fuel, remaining at the bottom of the chamber, out the exhaust port. No dynamic cylinder pressure increase here.
About 60 degrees before the end of the exhaust stroke, the intake valve opens, exposing the intake tract to the scavenge created vacuum now in the combustion chamber. If the scavenge vacuum is greater than manifold vacuum at that instant (say the throttle is wide open), air/fuel mixture will be sucked out of the intake manifold, through the combustion chamber, past the still open exhaust valve, and out the tail pipe. No dynamic cylinder pressure increase here. In fact, cylinder pressure will be reduced in the very next compression cycle because a portion of the available air/fuel has been lost, never to be burned. Opps, you have just lost dynamic cylinder pressure, the one thing needed to make power.
