The title says it all....
here are the pictures
Coming Soon to R-V6P.COM
Precat deletes replace your existing precats with a straight pipes for better flow. constructed of T304 stainless steel. ETA will be around the middle of June.
The precat delete kit will come with everything you need to run without any issues.
2 x OEM Honda Exhaust gasket
2 x Precat to A-Pipe gasket
2 x O2 simulators
6 x Stainless bolt |

Nice what about the Price...!!!!
How much are we talking here.... |

| empower me.. this means that you replace the crooked, stuffed up exhaust pipes and put these in and I get ? noticeable more horsepower, gas mileage etc? |

Based upon the pics which the OP said it all, a fairly stright pipe is replaced with a really striaght pipe. This appears to remove the pre catalytic converter and the O2 sensor.
The emmission and legal implications of this also appear to be obvious. Depending upon how emmissions are measured in your state, you could have issues. Some places don't actually measure the emmissions out of the tailpipe but instead connect to the computer module which calculates the emmssions. If this is the case and the inspector doesn't look at the new pipe and notice the difference, you might be ok. On the other hand, if they measure emmsions at the tailpipe or notice that new piece of metal next to all the old stuff, you could find yourself in violation of the law.
For the money and labor involved, I don't see this being a significant improvement in power.
When I went to Germany in 85 courtesy of the USAF, I was able to buy a pipe from Chrysler of Canada that replaced the catalytic converter since lead free was not widely available back them but it had to go back on when the vehicle re-entered the states. |

| Even if your state doesn't measure tailpipe emissions, if deleting the precat causes the OBD system to throw codes, your emissions inspector will see them. |

I'd really like someone to run an objective test to see if the catalytic converters really do what they are supposed to. A guy on one of my truck forums ran an emissions test on while on a dyno with them, replace the cats with straight pipes and reran the tests the same way. Same emissions results. He then drove without the cats and got 20% plus economy improvement. Reran the emissions tests and got the same results as the initial tests.
The cats may have been needed years ago before all of the fuel management systems, but is it possible that they don't really do much except drop fuel economy now? |

For that dyno test, it's not like the vehicle was driven through the range of conditions it would find- extreme cold, extreme heat, towing, driving in stop and go traffic.
For the operating conditions that the dyno test was run in, perhaps the engine was running under optimal conditions that would produce the least amount of emissions. |

the maker of these precat deletes is going to run the price of them under $300... for the kit... later on the line I am not sure
this is not spam whatsoever, i came on here to show you guys what the little cousin (accord v6 :2: ) is working on for the future...
quick answer to some prior questions
these will pass non-visually inspected inspections... the factory heatshields can infact bolt up to these so you can in theory pass visual, but I am not too certain
for states which plug into the obd2 these will pass because the computer will not throw a code... via the o2 simulator both secondary sensors will not read codes... primary sensors are designed for a/f ratio calculations so there is no need for simulators on them
Money and labor... as stated above the precat deletes will cost less than the price of 1 of the factory cats... labor involved is minimal, the engine bay on a honda pilot is roomy... all you need are the proper tools (a rachet) and a set of ramps...
hope I answered questions
lastly should anyone think about the pollutants... there is still a 3rd cat which will in fact operate so you will still pass knox if your state dyno inspects |

Dyno test was done in accordance with PA Emissions testing requirements. IIRC, it requires a warm up and is done at specific rpm's. While it may not be perfect, the test raised questions as to the worth of the cats.
Remember that there is only one company that processes the precious metals that goes into these convertors. I wonder if they have a lobbyist?:rolleyes: |

| and I'm sure they eventually handle all the recycled metal from all the cats that get stolen (which has been happening a lot around here lately...cordless sawzall) |

I think it is SPAM.
On the technical side, what happens to all the hydrocarbons that don't get burned since there is no pre-cat?
I would guess they end up in the cat forcing it to run at higher temps and shortening its life. |

Sounds like SPAM to me as well.
stillhere153, do you even own a Pilot, or did you just come here to market (SPAM) your product? Unless you plan to become a Site Supporter, do not continue to SPAM our site.
Thanks!

it is not my product... the website belongs to a member on v6performance.net
... I joined to make those aware like me who are coo coo and would run catless (on the track of course) :2: that the product exists...
not spamming at all... spammers don't come back and discuss products now do they?
ps. I own an 07 Acura TL Type S |

Oh please. This is like wondering if cigarette smoking really causes cancer or driving at high speed really lowers fuel mileage. The science and efficacy of catalytic converters is well proven and not some conspiracy. Do you also believe the oil companies are keeping us from 140 mpg carburetor?
You can sometimes remove cats and get some cars past state emissions tests, but that's because the tests are not very stringent - they're designed to weed out the "monsters" that have 100x normal emissions, but they will let cars past that have 2x or 5x normal emissions.

Well proven by whom? By the same people that believe that ethanol is a viable fuel solution?
As an engineer that has had to deal with government agencies and some of their requirements, I don't believe everything they tell us or some of the data they cite. Most of them don't have a clue as to what they are talking about. All I really would like to see is an unbiased test of the benefit of catalytic converters. If they reduce emissions by 5%, but create a fuel inefficiency of 20%, are they really helping the environment? |

I am not a big mac guy... but macphanatic does prove a point... if they "convert" the knox yet result in wasted fuel doing so, the amount of fuel needed to compensate the waste will cancel out the "good" cats do...
so in actuality it is like :1: |

Hu?
You don't think Cats help emissions at almost no loss of efficiancy?
Based on? |

Again, you're asking if the world is really round. Basic catalytic converter technology was developed in the mid-70's and has proven over the years to be reliable and very effective. It would not be remotely possible to reach the current level of emissions in today's cars without this technology.
Now, you sound like you're into the whole "government and regulation generally sucks" mode, so I'd just as soon not get into the discussion of whether catalytic converters are overall cost effective or whether we need emissions controls on cars in general. That's a political discussion.
What is germane to this discussion is what happens if you remove the cats from a modern three-way catalytic converter equipped car designed to use cats. And what happens is the emissions increase quite dramatically with either a loss or no change in fuel economy. So other than minuscule weight savings, the ability to use leaded fuel, and, of course, avoiding the expense of the converter at replacement time, there is no advantages whatsoever to taking the converter off a modern car.
Now if you could re-engineer the car's fuel injection and emissions controls systems with the assumption there would be no converter, you could potentially make it slightly more fuel efficient and offer slightly better performance. Catalytic converters to have a small cost in efficiency in return for their ability to reduce emissions to a vanishingly small levels. But this is an effort well outside abilities of a home mechanic.
