my friend Alessandro who live in Bologna ant have a wonderful blue 456 GT brought his car to my workshop last tuesday, one year ago he purchased from me the back mufflers with valve and now he want to install all the system, the 6-1 headers with the 200 cps CAT and the centre H-pipes that i done also for the 456 (i have it for both GT and M).
Yesterday i removed the original centre muffler and the two CAT, tomorrow the mechanic of my Ferrari dealer will come to me for remove original headers and install my.
I prefered ask help to the dealer because he know well the car and i not want that anybody could tell "you don't installed it perfectly ..."
My brother claudio wiòll installalsto the kit for manual bypass opening.
The 456 GT have not the downstream lambdas, then could run also without CAT, but my friend prefered to have.
Fabio- That is great. Did not realize you had a full 456/456M exhaust available.
i did one year ago the mufflers, i did approx 6 month ago the centre section for both models 456 GT and M, about the front system i only needed the OE 456 CAT for take dimension of the termination because is different from the 550, but the 6-1 headers and CAT for the 456 are the same that i do for the 550.
My friend Alessandro wanted the CAT, but his 456GT that have the Motronic 2.7 (have not the downstream lambdas) car run good also whitout CAT.
Now with the OE CAT i can modify my equipment and i will be able so supply the complete exhaust for the 456GT and 456M.
Unfortunately i can't supply the front system for the RHD cars.
yesterday night we finished the installation of the exhaust system of the 456GT of my friend Alessandro, we spent more time that we scheduled because we found (as i explained in another thread) a clash betwee the exit pipe of the left CAT and the chassis, i solved by modifying the pipe geometry.
I wrote 'we' because asked help to the mechanic of my Ferrari dealer, i prefered that him worked on the car.
When i started the engine ..... it did a dream sound .... i like very much! It appear a race engine, no drone but a very dry sound .... like my 575, and at valve closed just quiet...
