I want my 355 to wail when I floor it.

[stompboxx]

My 355 (with Tubi) makes a wonderful, deep, rumbling sound at low revs, which is great and I'm very happy with it.

When I floor it, however, I really want that high-pitched Ferrari wail to kick in, and it just doesn't...it's just a louder version of the low rev noise.

Would getting a decat get the wail I'm looking for?

I think the ideal solution would be to get a Capristo, but that's going to be big £££ I'm assuming? Is there a cheaper way using the existing Tubi?

Is your byepass valve working old boy?

[baptist]

Get your bypass valve checked, mine wasnt working when i got the car, and it just didnt scream at all.
But to make it really really scream, your going to have to ditch the Tubi for a Capristo, I've had both, and their really is no comparison between the two.

[burriana]

Tubi for 348, Capristo for 355 ... can you wire the bypass valves open on the 55 like you can on the 60?

De-cat will help and makes the engine seem to rev more freely but you will need to do some serious sweet talking come MOT time. Maybe try some Hyperflow cats.

[renmure]

Tubi, Decat, SCREEMING noise at full revs (and no probs with MOT) here.
I suspect your bypass valve isn't doing its' thing properly.

I have a tubi with decats and mine wails quite nicely, so maybe you dont have to splash out on the capristo.

Capristo stage 2 rocks.

That's the sound... and the info


How much are Capristos then?

[bromers2]

Go for a decat. And FYI the Tubi doesn't have an exhaust valve.

[baptist]

Capristo are 1900 + VAT.

Proper working exhaust valve and tubi will make a lovely noise, but nothing like the sound the Capristo makes.

I had a Tubi on mine, and while it was being fitted, i heard a Capristo, and i was gutted. Drove it back from Verdi's trying to convince myself that the Tubi was the right one for me, but in the end, just sold it and got a Capristo. Pure F1.

s/h one for sale here (although old ad, might be gone now).
You need a Capristo. trust me.

My 348 has a Borla Sports exhaust and sounded good but was a very deep noise.

Rather than buying a Tubi I went for De Cats first and that completely changed the tone.

It screems now and is a lot louder so I'm glad I didn't spend a fortune on another back box.

Just wire the valve open. It is a simple job. There are a number of 'how to' threads on F Chat.

Good luck

capristo sthis is cool,, from the Capristo site

"This is a wireless remote control conversion Kit. It controls every series-exhaust and Capristo Exhaust. It opens and close the exhaust gas valve. "

I know of 3 people who fitted one to their 360's and one to an F430. All but one had problems with the remote talking to the sender unit and had to virtually be 3 inches apart for it to work. And then, on one installation to the 360, it had an intermittent sticking valve which also rattled/resonated. I did consider the twin-sound setup, but after reading about these problems, decided to go straight to the level 3 instead.

One guy I know, who has a successful twin-sound install, never uses the lower setting, it's always set to max!

Your cat bypass valve is stuck/broken.

You know that little rubber air pipe that connects the valve to the air rail? They are known to rub o the heat shield causing the pipe to leak the vacuum that opens the valve. Have a look, that may be the cause rather than the valve sticking.

Is there any chance of getting a picture of this?
