365 BB exhaust system

tubi makes headers for boxers, unsure if they are in both arrangements for 512 and 365 though. You may be able to buy a complete system from them just not concours correct but it will fit, hold on to your wallet though!

 

Good day,

I believe that http://www.stainless-exhaust.com can fabricate your headers. I enquired some time back (March 2006) about stock 512 headers and quoted around 650 GBP for a pair (I only needed the lower ones). In my case, I found some excellent OEM ones from GT Car Parts and so I went this route.

Cheers,

Sam

 

How much is too much? what kind of money are we talking here for 365 headers? The reason I ask is my 512 has 365 headers and they're near perfect.

 

www.larinisystems.com

they make the complete exhaust system. the headers will fit a 365 or a 512 and are a real work of art. but like any great art they do not come cheap.

Very nice indeed! That system is a copy of the asna sport set-up like on my car, the combo of a 365 header with the 512 2 can muffler system but shiny like the stanley cup.

 

Important to know about Larini Ferrari headers

The Larinis are indeed nice looking having bought a set for a 3.2, but I did send them back for a set of Tubis because they were not what I expected. The important thing to know about Larini headers is that they look terrific, BUT are NOT mandrel bent like tubis or other higher end headers. In fact, if you look closely at the picture, you can see the narrowing of the pipes at the bends. Now, this might not matter so much to some folks primarily going for looks, but there is some flow restriction over the harder to manufacture mandrel bent type.
Pay your money and makes your choice.

 

Hmm,

Not so sure about that. When I had Tubi fab a system for my 365bb, the question was asked if I wanted headers, as well. They said at that time that they did have the templates to make them. Considering that mine were in great shape...and that they wanted North of $4,000 USD back in 2002, I passed.

I found my email that gives more info on the Larini system:
>>>
Our ‘Sports’ Manifolds are similar to the Ferrari 365 BB manifolds, which incorporate larger diameter pipework than the later 512 BB manifolds. Hence, they offer less flow resistance and better flow rates – critical for aiding even better performance from the 512’s Boxer engine

Ferrari 512 BB, Larini 'Sports' Exhaust:
- A Stainless Steel, 'fast road' use sports exhaust system, from the manifolds back.
- Engineered for 'fast road' and 'normal road' use.
- Delivers an extra 16 bhp. approximately.
- Offers improved low-mid range Torque.
- Much sharper throttle response.
- Offers better quality sound across the rev range.
- Features 4 authentic, Slash Cut, ‘Mirror’ Polished Tailpipes.
- Engineered for maximum flow efficiency, using heavily redesigned box construction and 'straight - through' pipe work.
- Accelerated gas-flow reduces engine bay temperatures, protecting the manifolds from damage, while optimising performance.
- Produces the sophisticated, ‘tuned’ authentic Larini 'Note' under acceleration when 'pressing on'.
- Produces a fantastic, subtle, aggressive ‘tone’ under acceleration, in keeping with the sporting image of Ferrari.
- Perfectly practical for everyday use: does not suffer from drone, resonance, 'boom' or vibration at idle or cruising speeds.
- Constructed using aircraft grade T.304 Austenitic Stainless Steel.
- Features double skinned boxes with flush endplates for maximum durability.
- Features ribbed muffler casings for 'original' aesthetic appearance.

Ferrari 512 BB, Larini 'Sports' Manifolds:
- Stainless steel Manifolds, similar to the original Ferrari 365 BB headers: a fine design indeed, engineered for optimal flow efficiency.
- Perfect for 'fast road' or 'normal' use. THESE ARE ARGUABLY THE WORLDS MOST COMPLEX ROADCAR MANIFOLDS.
- Constructed using aircraft grade T.304 Austenitic stainless steel.
- Completely 'mirror-finish' polished, including pipework and cylinder head flanges.
- Precision engineered for accurate fit to the cylinder heads.
- Requires no special procedures to fit.
- Precision engineered for accurate fit.
- Precision, laser cut, stainless steel mounting flanges and brackets, for easy fit and removal.
- Require no special procedures to fit.
- Completely mirror-finish polished, including pipework, flanges, boxes and Tips.
- 100% Tig welding construction.
- Precision, laser cut, stainless steel mounting flanges and brackets, for easy fit and removal.
- Precision engineered for accurate fit. Requires no special procedures to fit.

I looked into this because my ANSA can muffler was rusted out. But I did not want to invest the $$ they wanted so I found an ANSA can on the shelf. IRC- the Larini full system was $15K USD and the exchange rate has only gotten worse.

I would contact Dick Fritz at Amerispec. He may have a set of 365 headers or a complete system around.

 

The headers all interchange from engine to engine its the mufflers that complicate things. The 365 is even worse because of the pee shooter tips at the extreme ends of the bumper. For correctness you need 365 headers and exhaust, the car is worth the trouble and cost. I was priced some tubi headers for my boxer a couple of years ago but I forget the quote but I did fall off my chair, that I know. Unfortunately you need to spend some serious dough, goes with the territory.

 

you are going to think i am nuts, but i am serious..... find a local shop that makes exhaust for dirt track cars and drag cars. a good shop like this should be able to make it from stainless also. many scratch built race cars have to have custom made exhaust.

i have had custom ferrari mufflers made here by a local shop for $400.00. they saw the factory (ancient) headers and were chomping at the bit to make a set of those two!

they need to have the car there to fit the pipes, so its not a good choice to choose a place far from home.

 

Good day,

I think that the headers are pretty difficult to fabricate given the number of flanges, bends, hole positions, etc... Even the header to head flanges will cost a few bucks to waterjet cut (unless you can find these flanges somewhere, or perhaps you will reuse the existing ones). Add to the fact that you have 4 headers with 3 pipes each, all bent at interesting angles... sandwiched together, each two (headers) are vertically stacked, and then having all the holes matching up to the muffler is not an easy feat. That is not to say that it can't be done, but is difficult and time consuming which is costly. So I think for Stainless Exhaust in the UK charging 1300 GBP (total for 4 when I last checked) for 304 stainless mandrel bent headers is a reasonable price. If your local muffler shop can do the equivalent job for you, then my hat is off to them, as they must be true steel artisans!

Cheers,

Sam

 

If the Larinis are not mandrel bent, they are not worth having IMHO. I would have a custom set made by a local race shop or buy some OEM take offs from Dick Fritz at Amerispec...
