Full titanium exhaust with stainless downpipes? How is that a full titanium exhaust?

Ti catback. Bumping diameter to 2.5"
The secondary cat/downpipes could be Ti, but for longevity in that high heat area of the exhaust we decided on stainless.

I'd be very hesitant to change tyre brand for the saving of a few kilos. Adhesion is much more important and I personally would never change from the Michelins. They transformed my 550 when I swapped over.
Weight has nothing to do with the stickiness of the tire.

18" Rear:
Continental Extremecontact with 340 treadwear weight 27lbs
Michelin Supersport with 300 treadwear weight 27lbs
Yokohama A052with 200 treadwear weight 27lbs

19" Rear:
Continental Extremecontact with 340 treadwear weight 27lbs
Pirelli PZero with 320 treadwear weight 30lbs
Michelin 4S with 300 treadwear weight 29lbs
Michelin Pilot Sport Cup 180 treadwear weight 26lbs

My 575 is going on a diet.

Currently building a full titanium exhaust, with valves, and stainless equal length downpipes. I expect this to drop at least 100lbs off the car.

I pulled the inner foam out of the steering console while de-stickying it, 3lbs dropped. I never thought weight could be lost there, lol.

Next up for me is coilovers, which should drop a few pounds over the OE units. Followed with light wheels; 2 piece brake rotors (4lbs per rotor) and some Ti hardware (2.5lbs for lug bolts)

Some other areas to think of for easy weight reduction:

Headers would drop the weight of the factory manifolds/cats (possibly SAI system) and downpipes.

Brand of tire. Different tire brands and models have different weights.

Brand of battery. Like tires, different brands and models of a battery have different weight. Generally Deka is significantly lighter than other brands. A smaller battery is also an option.
Please keep us informed as your weight loss project progresses, and what you're doing to reduce lbs. Be interesting to see how many lbs you eliminate and what all you did to get there.

Dropped 109.60lbs with the exhaust while retaining the stock manifolds. Fiammenghi headers & downpipes would shed even more weight.

Stainless:


Titanium:

New 18" HRE 305 came in and they weigh 24lbs less than the factory wheels and are wider than the factory wheels at 10.5" front and 11" rear. These are not considered a lightweight wheel, so further weight reduction could easily be obtained with a light wheel.

Onno, last year when having its major belt service I put Michelin Super Sports on my 575M. They have met all of my expectations.

Michelin is the best tire for our cars.

I just bought PS4S from 4wheelonline last month. These tires are better than the Pirellis. They are very grippy and smooth on the highway.

Lets get some facts and figures in this thread:

Stock seats weigh 58 KG for the pair, I believe excluding the electric motors + assembly to move them back and forwards. I can't check now as I'm banned from fchat again, they truly lost the plot over there. Depending what type of seats you go for, you can save as much as 46 KG.

Battery weighs around 18KG, a large lithium battery weighs 3kg. So 15 KG saved there.

Stock exhaust cans weigh an impressive 19kg EACH (!). Replacing them with a set of Fabio's valved items you'll save 24.2 kg, or the unvalved versions you can save as much as 30.6! And that's just the cans...I hope @Fiammenghi Italia can advise how much can be saved over the rest of the system, I suspect quite a bit with the 6-1 exhaust! Lets put a very conservative figure of 60kg savings for the exhaust.

We've now saved 121kg without even trying.

There's quite a lot of weight to be saved in wheels (important weight too, as it's unsprung), but I'd be careful on that as not many wheels suit the Maranello well....

120KG heavier than a dirt bike. That's a lot of weight to be removed. Full set of Fabio's exhaust will unleash decent extra power as well, I believe close to 550bhp. Modern tyres, brake pads, better brake fluid...will be cheap fixes that makes the car feel better without negatively impacting anything. Power to weight ratio with this will be about on par with a 599 GTB.

Thanks all for your contributions and interesting feedback.
BAS, did you weigh the car after removing 121kg, and if yes what was the figure?

Not me, sadly, but I've spend a great amount of time verifying certain parts of the 550. Without a 550 until I return to Europe hopefully early 2021, plan is a 550 build with substantial weight loss (aiming for minimum 200kg lighter, which actually isn't too hard on a 550, but also keep it very streetable). Build will be inspired by the Ferrari 360 CS, 599 GTO, Trev's 360 manual CS, and of course Ferrari's own abandoned ''575 Challenge Stradale'' project.

I have been trying to start a new topic but its approval has been pending since yesterday. Is there a moderator around?
