I completed the set of straight pipes for the Ferrari 550 of a friend of mine from Forlė, he came to pick them up on Saturday and if he installed them alone yesterday but due to rain he didn't test them on the street, he has my 6- 1 headers without catalysts (Installed by Sauro work shop in Bologna last year) and all the rest of the original.
Before ordering them he came to me and we took a ride with my low gait with open valves, according to him you can circulate as long as you don't push too hard on the right pedal ...... Given then that he is a fanatic of weight, for these reasons he opted for the direct tubes that weigh 3 kg each against the 16 kg cd. of the original silencers and the 7 Kg cd. of my sports silencers (but they cost much more).
Next Saturday if it does not rain should come to see me with the vehicle so I will feel it ....
