The weeks-long process of coordinating the fabrication of prototypes, fit-testing and final installation of this tuned exhaust system was done by the master Ferrari mechanic, Dave Helms, at Scuderia Rampante, Boulder, Colorado.
The hand fabrication of prototype catalytic convertors and x-pipes was done by
Hyper-flow which resulted in a tuned exhaust that may be only 5% less efficient than race-only straight pipes.
Video of awesome (before/after) performance increase
One guest driver from Salt Lake remarked that the 550's acceleration performance exceeded his 575M's. The 550's mid-range power is now around 520hp(from a stock 485hp) and the stock 420 foot pounds is now about 450 foot pounds.... with the torque curve going all the way to 7,000 rpm - instead of hitting a plateau around 5,000rpm!

p> In November, 2004, my little 550 was chosen as "Showoff of the Month" at CarDomain.com,
a website with over a million members!
And a month later, it was chosen "Car of the Month" at Ferrari Haven!
"Yes officer, I'm an egotistical hotdog in a Ferrari!"
