Hello at all,
During the installation of my system on the 456 GT i found a clash bethween the exit tube of the left CAT and the chassis, the car body in that point have a bulge, we are in the pedals area, the body is a little bit diffrent from the 550-575 in this point, i think due to this is a 4 seats car, Factory moved a little bit forward the front passengers, then wanted additional space for pedals.
I modified the pipe of the CAT and i updated my welding mask with this point and i added the end point of the original CATs, in order to be able to reproduce those part for eventual future clients.
With this update of my mask equipment, now, i can do all the exhaust system for both 456GT and 456M.
Following the pictures of the two extension pipes for the 456 GT that i did for coupling between my 200 cps CATs and the centre section (original or my have the same interfaces).
Note: my headers and CAT are able to fit on LHD cars, not for the RHD cars.
starting to the hypotesis that in RHD cars the steering shaft is in the opposite position in respect to the simmetrical plane of the car body, in my 3D CAD model i have a clash between steering shaft and the right CAT, then the solution is to move the two CATs under the car, where it was the originals, and install two simple pipes from the 6-1 merge point to the CATs.
