F430 sport exhasut

Hello guys,
new projects are coming ...
I closed an order with my dealer for make the exhaust for a special F430 (4.7 litres, 550/600 HP ...) that will go to the gumball 2017 (Riga to Mikonos)...
I taken the occasion to make a 3D model of the engine-gearbox and of the OE exhaust parts in order to are able to design at CAD a new exhausts and headers for the F430.
Is my intention develop some exhaust parts to put instead of the orginal, one by one, and also to make a complete differen system ...

Best Regards

Fabio

If you can design a header that wont be so loud like the other aftermarket headers are you would have some buyers for sure.

Hello guys,
today i completed the exhaust system for a customized F430 that will participate to the Gumball 3000 Riga-Mykonos, my exuaust will coupled with a set of F430 GTC headers (without cats), and engine displacement increased to 4.7 litres.

https://www.gumball3000.com/blog/2017-riga-to-mykonos

I could not make the exhaust system directly on the car because now is disassembled in the bodywork, I used the 3D files of the engine, gearbox and headers obtained by laser scanner, that i assembled on my CAD for make design.

Note that the flanges are made by my design, male and female with a small turned reliefs for have labyrinth effect and in the connection surface have the grooves for graphite seals that i ordered per my drawing.

On the last pictures are showed the cross support plate, the mold for beading the bottom plates of the muffler and the connection flanges after CNC machining.

Delivery next week, i hope will fit good ...

Best regards at all who will pass from here.

Fabio

Very well engineered exhaust muffler, congrats!! Just a question: why did you go for 4 to 1 exhaust headers rather than a 4-2-1 solution?

Ciao Stef,

- for the customized F430 the 4-1 headers was a customer input.
- for my headers i prefered to do for a 4-1 because i want do the same interface to the original headers and with this limit there is less space for do the 4-2-1 headers with pipes with sufficient lenght for have good torque at low-medium rev, also if the 4-2-1 is indicated for the 4 in line cylinders engine.
With the 4-1 i can make more length pipes, that is good for torque at low-medium rev.
This was my thought....

Best Regards

Fabio

Stef- The 4-1 headers will make for much better scavenging than a 4-2-1, just like they do for V-12s with 6-1 instead of OEM two 3-2-1 headers. You also get a much higher pitched sound with each exhaust pulse extracting the next and there is a pretty significant increase in hp. The GTO went from the 599's 3-2-1 to 6-1, and most of that beautiful sound comes from the header design, elimination of precats, and use of single large 200 series cats on each side. Same principles apply to the flat crank V-8s.

Not the same as a 90 degree crank V-8, where a cross pipe can increase hp from the 4 V-2 layout. Our V-8s are two inline 4s on the same crank and one of the big advantages is the exhaust pulses are self extracting.

Hi Fabio,

Nice to se that you are starting to work on an F430 exhaust and headers. I look forward to seeing more information from you on it. Will you be using Titanium or Stainless Steel?
