TUBI TEST PIPES

All of the above. I pulled the cats from my F40 and replaced them with test pipes. Depending on the model of your car the pipes will have a definite effect on engine characteristics. I had to adjust the turbo wastegate to compensate for removal of the cats. Also, when I swapped cats on my 550 I noticed a decrease in low end performance - my dealer explained it was associated with the decrease in back pressure but assured me that I would make it up on top end (Like I would ever see it) Also the check engine light stayed on continuously..I ended up putting the cats back in.

I was going to leave this one alone, but.............
I don't believe it is anyone place here to judge others and that is the impression I felt from your post.
The next thing you know we are going to have peole posting about needlessly spending money on a car that could have provided food and shelter to the homeless or the folly and reckless endangerment involved in speeding etc. If the biggest crime people commited against humanity was removing their cats, the world would be a far better place.

Let us leave advice/debates at a technical, not judgmental level.

BTW I do agree with Maranelloman, the performance improvements are generally not great and the hassle caused by getting caught is not worth the problem. If you are concerned about performance, buy 100 cell race cats instead, if it is for sound only change mufflers instead.

 

Same logic dictates we should all be driving either electric or hybrid electric cars.....or better yet mass transit and do away with our passion that at best gets 18 mpg. or even better yet....bicycle or walk.

I am in full agreement with Maranelloman on this. Sure, in a perfect world, we would all drive electric cars and eat organic veggies but pursuing your passion for performance cars and purposefully increasing your already high emmissions, that as he pointe out, that degrade the air we all share are two different things. You could make a good argument that it is a fine line but cats should stay on the car, or at least be hi flo variety. Just my 02cents worth.

 

(I prefer to run cats on my cars, but I can't help asking...)

maranelloman -- Do you also consider having children as "BEING A NEEDLESS, SELFISH ACT THAT MAKES THE AIR WORSE FOR THE REST OF US"?

 

each to there own but i would rather swallow exhaust fumes and be deafend by noise from the tubi than die from passive smoking{me being a non smoker] i dont know what all the fuss is petrol cost you lot $1 a gallon move to england and pay $7 a gallon so really you are getting poisned on the cheap in the usa you dont know how lucky you are over there

 

I think you need to go preach on an SUV board, those are the real enemies. Daily drivers sitting in stop and go traffic for hours, THOSE are the people who should be ashamed, not the few of us that put a few thousand miles on our cars for fun, we are akin to Nascar, not the predominate population.

 

Test pipes are the only way to go. Catalytic emissions crap is just more left wing gov't from cradle to grave non-sense. When the libs voted in the 1.6 gpf toilet as the new standard touting how much water we would save nationally, it now takes 3 flushes to get down the same pile of crap, so where's the gain? Besides, why would you want to pis off Enzo?

 

This is a interesting discussion. I have noticed that Maranelloman (Clint Eastwood) LOL has been flaming everyone who even mentions test pipes for some time now. And everytime he does it he invokes the threat of federal jail time. It seems to be some kind of emotional crusade that Clint is on. I agree with an earlier post on this thread, Clint you need to chill out and get off your high horse. This forum is a valuable source of information and ideas and I am sure that you are a valuable contributor in many ways, but IMHO this obsession with test pipes isn't helping your credablity.

 

Marshmallowman: Since we are breathing the same air do us a favor, close your trap and save us your CO2 discharge!

 

Only 3 flushes, Frank? Email me your address. I have some breakfast cereal to send you.

 

Hey Sherp; it's just fiber and fumes. Marshmallows probably got a cat stuck in his 1.6 MPG.

 

I'm sorry, but this is self-righteous hogwash.

1) If you're *really* concerned about the air you breathe, why don't you lobby your government to increase the cost of fuel, and to seriously encourage less waste of natural resources? You should also get them to have a cohesive policy on the use of electricity by your nation. And perhaps to join in with International accords on such usage, rather than refusing to in a bid to protect industry.

2) If you're *really* concerned about the air you breathe, sell all your cars and buy push bikes for your family.

I fully appreciate your point about us having to do something, but let's get a sense of perspective. How much extra pollution do you think is being caused by Ferraris with test pipes on?

Do you have *any* empricial evidence that shows that the "harmful" emissions produced from such cars are measurably (let alone significantly) greater than those fitted with cats?

Furthermore, do you have any empirical evidence that proves that any such savings (if there are any) are not offset by the pollution caused in producing a catalytic convertor and disposing of it once it breaks it down (remember that in a Ferrari's life time it'll probably chew through a couple of sets of cats at least). You wouldn't want to be breathing the dust from a convertor, after all!

Doing something about the environment is a serious business. But we need to focus our energies (sic) sensibly to make any difference whatsoever. Car emissions count for a minute percentage of "harmful" products worldwide. Power stations and other sources are a far bigger problem. How big is your house? How energy efficient is it? How energy efficient are your kids (with their TVs, XBoxes, DVD players and hairdryer)? How much food do you throw away each day and how many 5 quart drums of Sunny Delight does your family get through daily?

It's all well and good telling people not to justify their actions against "bad" actions. But preaching as you are on a forum like this is hardly going to further your cause now is it.

As to why you'd do it, well if you heard the sound of a car so equipped against one that isn't, you'd know instantly. It's not about power (no gains) or the race track. It's about getting what you want out of your conspicuous consumption. And if you start down the road of being self righteous in that area, it won't be long before Ferraris are all sat in museums.

 

Dave,

Don't worry. No one will tell Art you moved a notch over to the left!
