The exhaust system for FERRARI 599 GTB V12 Fiorano is composed by
High performance long tube headers, equal length, which replace the OEM primary cats.
Front Y-pipes, available with high flow metallic cats 200 CPSI by HJS Motorsport, or without, as decat pipes.
Centre x-pipe
Connecting pipes, also available compatible with OEM mufflers (which are equipped with bypass valves)
Rear mufflers with 90mm tailpipes, direct flow internal design.
CAUTION:
Fitting the headers and front Y-pipes, with or without sports cats, will result in the triggering of the Check Engine Light, caused by the secondary O2 sensors reading the wrong values.
An ECU tune is COMPULSORY, the "faulty cat" error must be blocked or the secondary lambda sensors must be deactivated.
