Possible to have GTO exhaust note on 599 ?

George- It is all about extraction of gases and smooth flow. 6-1 headers do the best job of extracting exhaust gases with minimum back pressure. As a side benefit, they sound better, too. Fabio's system actually shows gains of around 50 hp over the stock 3-2-1 system on the 575M, part of which is due to the elimination of the precats in the headers. Note the GTO also went to 6-1 headers and primary cats only, and that is where part of the extra HP came from on that engine.

It is illegal to run without cats, not that that seems to bother some folks.

 

Im considering selling my car,so if anyone interested for the 6-1 Fabio's headers pm me!

 

Thank you, this now makes sense!
