I have this system fitted to my +8 , in truth it is overcomplicated , has too many joins, and yes it does heat the oil in the sump.
Having said that modern oils are designed to be run at much higher temperatures than previously so I don't feel that is an issue.
Apart from the need to maintain all those joints and keep them airtight the only real issue I have is the under bonnet heat dissipation. Almost every bit of room under each side of the engine is filled with potentially hot piping. This makes heat dissipation quite serious when we experience a summer like last year. It does however warm the car up very quickly in the winter.
If you fit it you MUST crossover the lamda sensors , or they will feeding back to the wrong bank of cylinders.
The big advantage of this system is the much longer primary pipes that are rendered possible by the crossover design. The certainly helps mid range torque, and gives a really nice sound.
However IF I had my time again I would certainly go with the current Librands system where each bank just exhausts down through the chassis on the same side. I don't think you lose much power by doing this , and it would make the system so much simpler.
