Here is a video of a Magneti Marelli SS500T on my 1.4 100hp
The exhaust is designed for the 0.9 twin air so some minor modifications are required to fit it to the 1.4.

It is basically a straight stainless steal pipe so sound great when you put your foot down but isn't annoying at idle as the center silencer cuts out the drone.

Any questions please ask! :)

sounds good. I am thinking of getting o e for my 1.2 from 500 madness store.

But it is about USD $750 delivered. Might be better going to a local specialist and have one custom made. Just not sure if locals can make it sound as good as magneto marelli one.
 
The Marelli Exhaust is just a poorly made bit of pipe. The local exhaust shop one will sound the same and probably flow better.

Other than the difficult of welding the thin OE exhaust, you could also just cut out the resonator and weld in a straight pipe for the same result.

The Marelli Exhaust is about 2kg heavier than stock, too.

In time I might replace my MM with a Ti version out of Japan, although I can't seem to find them for sale at the moment.

I get what you are saying, I presume you had a MM exhaust before.
But, if you go on YouTube and listen to f500 1.2 and 1.4ltrs with and without MM exhausts, the ones with MM exhaust sound so much better.

I currently have the MM on my TA.

But do MM sound different to say Ragazzon?

If we were talking about replacing OEM mufflers (or complete systems with CAT and all) with 'sports' ones, then you could certainly get different sounds from different makes.

In this case, we're just replacing a muffler or resonator with a bit of pipe, not much scope for different approaches to sound all that different.

I just listened to both of them on YouTube and to me MM sounds more 'gurgling', for the lack of better word.
I'm on mobile so can't link videos.

Just search Fiat 500 1.2 magneti exhaust and then Fiat 500 1.2 ragazzon exhaust and compare.

To me they sound different.
 
Rear exhaust sections designed for the 1.2 appear to all still have silencers, so yes, it's entirely possible for them to sound different (keeping in mind the vagaries of youtube videos).

The TA exhaust as posted by Otto is just a straight pipe.

The 1.2's all seem to only have a rear box, the centre pipe is straight bar the flexi?

Hi UFI,

The Marelli pipe I have is stainless steel and appears to be quite well made I thought, unless you had a custom pipe made in a thicker diameter I'm not sure how it would flow better as there is no restriction with the Marelli.

I can assure you that my Marelli pipe was significantly lighter than my stock 1.4 back box. If there is some weight difference to the stock twinair pipe I doubt 2kg is going to make an impact to the 500s performance in everyday driving.

Thanks! If you are after a straight back section you will be better off getting a good custom one made as it will be much cheaper :)

I love how MM sounds on 1.2ltr, at least from Youtube clips I've seen.

My worry is if I go to a local custom shop, they will not get the same sound that you get from MM exhaust.

Which local shop are you thinking of going to? :)
Personally I had good experiences at The Muffler Shop in Killarney Rd. They once had two goes (no extra charge) with my X1/9 before arriving at the perfect sound. Then they managed a great sound first time in my 164 V6, and then replicated the unusual muffler arrangement of my Spider TS. But maybe Hamilton isn't local for you!

I'm in Sydney, Australia, so I don't think I'll be going to Hamilton :).
I will go for Magneti marelli exhaust since I love the sound it makes and it almost should be considered a Fiat oem part.

Ah right, sorry, I didn't look closely enough at the tiny flag icon on the left side under your name; tiny on my iPhone anyway :eek:

No worries.

I just bought MM exhaust for aud $370, delivered to Australia.

If I bought it on 500madness, it would be aud $960, so very happy with the deal.
