Is Tubi the only exhaust manufacturer for F40

Fuchs exhausts are very popular in Germany because of their extraordinary build quality.
Never heard one on the F40 though.

Their website: http://www.fuchs-esd.de/ (Click on "English" to change the language)

 

Is there any special reason to not do a custom fab'd exhaust? @ the price of a Tubi, I think I would prefer to have one hand made by my local welding guru.

 

one of my favorite subjects. If you are looking for a muffler then you can't go wrong with a Tubi (although with cats it will be a very SUBTLE sound improvement) . For straight LM pipes you can go with Tubi or have a set made, I went with Tubi because the price was not expensive and it looks good. For cat pipes I recommend having a set made by a local shop as they must match EXACTLY.

 

Did any Euro spec cars come with cats, or just the USA spec cars?

 

From 1987 to 1989 there were no cats (and no US cars). Cats were introduced in 1990 with the US cars. From 1990 through 1992 they were a euro option. Suprisingly about half were spec'd that way.

 

MS Racing also makes one.

Wow, if cats were an option, I can't belive some actually ordered them!

Oh well. I have heard a F40 without cats, and a Tubi. It was quite a sound!

 

stradman here are some links I found when I was searching awhile back:

In some European countries for model years 1990 and on the official Ferrari concessionaire had to make sure they came in and were delivered with the cats option. What happened after that was up to the owner of course...

In looking at those fuchs, the quality looks very nice, its nice how they retain the oval exhaust tips, but they are mufflers. The germans like their cars very quiet! The exhaust expands inside the turbo's and that muffles the sound quite a bit already. I suggest listening to an F40 with mufflers before going that route, most folks end up with straight LM pipes (that will sound about like your stradale, still not very loud).

 

stradman I haven't heard of any problems with the tubi LM pipes, they dont have as many welds as say a 355 or 360 exhaust. The Tubi inconel pipes are stronger as they are made for all day racing every day of the week, probably overkill for street use. They do run cooler than stainless, as will ceramic coated pipes, and will allow you to remove some of the heat shields without destroying your back window, and looks very sharp. But with cats its a bit of a why-bother, just my opinion, since the cats retain most of the heat. Inconel and ceramic won't turn blue like stainless, however I like that look, the blueing is visable through the back of the car and looks awesome.

As far as flames go, there shouldn't be any problems as long as your cats are working (I didn't have any problems and my car was running rich). Without cats then I suspect you might need to protect your bumper from flames, especially if your car is running rich or when the engine is cold.

 

I did some looking around at exhaust pics in the showroom section to see how much of a concern the flames will be. Its an interest of mine as well since my car is going through the process now. There are several great shots in the showroom section that show the back ends of many euro cars all lined up, and a few looked a little smoky but most were fine. For reference:

Here's a pic of flames coming out the back of a car (obviously a rather extreme example, its not like flames would be constantly coming out the back like this)

Here's a pic of a taped bumper

Here's a car with burnt bumper

I've noticed that on my car (which has Tubi LM pipes), and on cars that have no cats and have no problems, the pipes stick out an inch or 2 more than stock (as seen in these pics)

A typical stock car will have its pipes flush with the bumper

On this car it looks like the pipes are set inside too far

So perhaps all that is needed is to just make sure you have the pipes stick out an inch or 2 to solve the problem.

 

Stradman,

They will spit flames IF the cats are bypassed, AND you are running straight pipes, and only on the overrun, accompanied by a delicious cacophony of 'snap-crackle-and-pop'

Please bear in my mind that I am not a technician, BUT I have 10 years experience with multiple F40s of my own, covering thousands of miles:

- I would set the car up with a 'no-cats/straight pipes' situation, simply because in England, you can (the USA engine will develop boost and other issues if run without cats long-term, according to the men who developed it).
- For a set of straight pipes I would go with the BEST. In my most humble opinion, that is the straight pipes unit that Tubi has built for the F40 in inconel. I have the first one and will report how it sounds etc. Inconel is used by the F1 cars and sports cars to race all day long and I am assured that the sound is better than stainless (more sonorous, less 'tinny'), it definately dissipates heat better, and weighs less. I would inquire early because I am told that they may not build these for normal production. Dont be suprised if the sales office denies all knowlege (you can see proof of the shipped unit on the USA F40 thread posted a few days ago).
- I would most DEFINATELY have someone specifically F40-experienced tune the car to match this setup. In my experice, the wastegate will have to be adjusted slightly in order to ensure you dont develop boost issues. Of course if your car currently runs a no-cats/straight pipes setup, this might not be neccesary. I am told that in England one of the best is Bob Houghton.

Then find a twisty road, add right foot, and enjoy...

If your car was built with cats I would leave them on.

Not always the case....this car has mufflers.

If you have the car tuned after pulling the cats you will be fine. MAYBE you might lose like 2 foot pounds of torque or less, but you will gain more then that in horsepower, and make it louder.
