YOU SAID:
Ferrari 456 Sports Exhaust – August 2009 – Tim - UK
Hi Paul
Just a short e-mail to thank you for a trouble free transaction.
The rear boxes are fitted and give a nice deep burble at tickover but the exhaust note is not at all 'boomy' or intrusive at motorway cruising speeds.
I think they suit the character of the car very well.

Your 550 system is the best sounding system I have ever heard.

Ferrari 550 – August 2006 – ‘WYO’ - USA
The one thing Fiat seems to have done with Ferrari, is impose a "global car" mentality on the design criteria for things like exhaust.
For example, the world's entire inventory of 550's all meet the tough Swiss noise standards.
OK, so here come the after-market exhaust system companies, chasing the gold - without ANY real engineering of performance into their products because most drivers just want a LOUDER car!
In my considered opinion, most aftermarket mufflers (regardless of make of car they're installed on) emphasize the mid-range of human hearing - with no regard to the harmonics that extend down into the sub-sonic and up into the ultra-sonic. They do this mid-range emphasis to make the system seem louder and more nasty!
But (in regards to Ferrari aftermarket systems) I personally find the Tubi/ Capristo sound crass and brittle because of their emphasis on the "LOOK AT ME" mid-range.
So, in 2005, I installed a pair QuickSilvers on my 550.
One manufacturer of $100,000 stereo speakers (and a 550 owner) says this is the best sound HE ever heard on a Ferrari, because of the harmonics being audible both up and down from the mid-range!
It gives the sound a resonance that I've noticed even deer in Yellowstone pay attention to...and smile at.

The performance improvement is immediately noticeable from 3K onwards.
In third and fourth gears, the car revs so quickly from 6K onwards it is impossible to not hit the rev limiter.
It is also pulling hard right into the limiter, so I really need an extra 500-750 rpm now.
I was hoping for an increase of around 30hp but it feels WAY more than that.
Removing the cats also saved 12kg, FYI

Paul,
‘Received them on Friday and had them installed today.
Amazing !! Already quite loud, my neighbors will hate me ...
Everything much much better, it's a real pleasure to really floor it and even at low revs it has a really deep tone, brilliant.
I thought about selling it, but now will definitely keep on enjoying it through the summer at least.
Thanks!’.
