    Hi does anyone know if the rear exhaust boxes from a 550 will fit a 456gt?
    I know the 550 has valves but it's just the physical size I am asking about.
    Many thanks
    Paul

    Been a while since I had my 456GT, but did investigate trying to install 550 rear exhaust, not going to happen. The F550 is smaller, has a different bend and shorter pipe. If your looking for a better sound from your 456, suggest you get a Tubi exhaust or Tubi straight pipes/tips. For me, I changed the center resonator to an X-Pipe and removed the rear boxes to a Tubi straight pipes. Very loud, but not a mind numbing resonate sound. More like a old 12 cylinder Ferrari from the 60's.

    hi, thanks for the useful info, I already have the x pipe in the centre and that makes a difference mainly from behind the car, but one of my orignal box claps has broken so I was looking at options on rear boxes. I was wanting not to make everyone turn around and frown as you are in town but liked the idea of being able open the valve when appropiate.
    Best Regards
