Yikes. Better get cracking with selling my relatives.

I found the Tubi too noisy and resonant, the Quicksilver replacement was easy to do and was just what I wanted, quiet around the neighborhood yet on throtle sounds like a Ferrari, and smooth response. This really fits the GT nature of the car.

Just sold a set of rear X-ost Maranello mufflers today. I installed them on a 2000 550 Ferrari . Sold the set with round tips. Client loved the look and sound.

Ron- The early Tubis (those not embossed with 575 on the cans) were noted for being loud and resonant, which some people love. The 575 Tubis are much milder.

Most of the aftermarket systems sound good if you do not go for their loudest option. the loudest systems still sound good, but are loud enough to upset neighbors and wives.

I have Quicksilver mufflers on mine and I believe they sound good.
I originally also had the straight through middle pipes, but I quickly reverted back to the original part. It just became too loud!
Whilst I agree that a GT should not be particularly loud, I just found the stock car to be just too quiet. I guess that's a personal view though.

I,m Very happy with the 2nd Gen Tubi...

cheers,

Maybe this has been discussed before, but at I have not found a thread (yet).
I have a 550 Maranello and would like to get the oldfashion V12 deep and agressive sound without the draw back of beeing "too loud" sounding like somone beeing 18 again...
I have removed the back pressure valves.
What would next step be ?
Straight pipes, X-pipes, K&N airfilter ?

Anders- First step on a 550 or early 575M is to replace the center muffler/resonator with straight pipes, which will get you max hp and torque, or with an X-pipe, which some people prefer for a different sound. In late Summer/early Fall 03 Ferrari replaced the 575M center muffler/resonator with straight pipes, so you know how the factory voted.

Then see how you like the sound. If too loud, reconnect the vacuum lines to the bypass solenoid or cut the wires holding the pneumatic valves open, depending on how you defeated the bypass valves.

In most cases 550s and early 575Ms sound great with OEM mufflers and straight/X-pipes, even with the pneumatic valves working.

[AndersJL]

Thanks, I will start with that:-)

Hi,
in the discussion "Looking for advices in buying a 550 Maranello" you can see my exhaust system who is as i want in that moment,
quiet when i drive between houses or loud for my enjoyment, only push a button on a console. Two face of same car.
In my system the butterfly valve close and open both exhaust pipes (dia 90 mm) non unly uno pipe like the original or the aftermarket.
I think are unique.

Fabio- If you close both of them, where does the exhaust go?

[550_Maranello]

Terry,
I'm sorry maybe I have not explained clearly,
the inlet pipe of the original silencer (perforated pipe inside the resonator) is direct to the exit and closed by a valve,in that case the gas go through only the other pipe, when the valve is open the gas go through the other pipe.
That is visible, one pipe is blacker than the other because in normally use the valve is closed for most of the time or vice versa for those who always keeps open.
In my muffler I put a V-line (inside the muffler, filled with ceramic fiber) in order to split the inlet pipe in two output pipes and the valve closes before the v, I put two perforated pipes (before and after the valve) for circulating the gas when valve is closed.
You can see that in picture that i attached some days ago in other discussion, that i know you are saw.
Probably when the valve is closed the conceptual of muffler could be improved, but the results is impressionanti, I have no resonance problems at low speeds typical of other very troublesome (between 1000 and 2000 rpm) and when i open the valve you hear a great sound, not only strong but beautiful.
Two different face driven by a button.

Fabio- Now I get it. Make sure you save that exhaust if you get a 575M. The 575M rear exhaust will fit your 550 fine. If you get an HGTC 575M, though, that HGTC exhaust is worth some money, so do not put it on your old car. I would even buy it.

[550_Maranello]

Hi Terry,
I have the original mufflers (central and rear) of my 550 and if I can find a 575 HGTC as i want (not easy), I want to remount the original mufflers on my 550.
On the 575 I think to I remove the muffler hgtc and install my , I also have to make me the new central pipes.
You would like to buy the two mufflers hgtc?
I know that are very expensive, I not think I sell them.
I have also the pipes with no catalyser, but i removed them because the slow down emegency in the dashboard was always on and the ECU worked in recovery sytem, I read those things on the workshop manual.Do
Do you saw my racing cars?

Fabio

[tazandjan]

Fabio- All the HGTCs, actually all 575Ms after Fall 2003 (Assembly Number 51797) come with straight center pipes so you will not have to make new ones.

I am a buyer for your HGTC mufflers if you decide to sell them. I have HGTC mufflers from a Superamerica on my car, but they are slightly different from the 575M mufflers.

[550_Maranello]

Terry,
you're right in the 575 after 2003 had a straight center pipes, the pipes are not between connected them, I tried a similar kind on my 550 but i don't liked the sound (a lot of low frequency), is for this reason that I have built a my central type where join the frequency.
The rpm perceived by the sound was low and i not like, i wish like a F1 V12, this will never be because the exhaust system is too long.
I think will be the same for 575, if I manage to find it.
Before you alluded to the superamerica, I love it very much,(I prefere the line of 550/575 but superamerica is a V12 spyder) now in italy there is une red with black interior , hgtc, 3700 km but the price is out my budget .. (140.000 euros).

[tazandjan]

Fabio- Some people like the sound of an X-Pipe better, and it only costs you a little hp and torque over the straight pipes. My car with OEM straight pipes and HGTC exhaust sounds pretty good. 550s and 575Ms respond slightly differently to exhausts because of the precats in the headers of the 575M.

Just returned from european trip - drove 800 miles today (2,800 in 10 days) Last year's european trip was 550 with centre silencer and tubi rear boxes, this year straight centre pipes with standard boxes. Having tried both, I prefer the latter - no tubi drone at idle, quiet in traffic & town, peaceful conversation at 3,000 rpm on highway. When valves open, much crisper exhaust note. Highly recommended.

[tazandjan]

Orled- Welcome to Ferrari Life. Straight/X-Pipes and OEM mufflers are always my initial recommendation to Maranello owners before Assembly Number 51797. Once that cork is out of the middle, the car sounds great. The early 550 Tubis (no 575 embossed on cans) are known for their droning. Plus with straight/X-Pipes, they are too loud for most owners.

[550_Maranello]

Hi Orled- Straight Pipes and OEM mufflers was my initial solution for my 550 Maranello, the results quite good with a push button in console to bypass ECU.
I wanted a sound with a strong character and low noise when i drive in town; so that I did the system what you see in the image above.
