|
|
Hi all,
I'm getting our '77 Sud Ti back to a fit state for club supersprints here in Melbourne. I'm planning to run in the 'base modified' class which allows some modification (suspension, internal engine mods) but no change to carbs or exhaust.
The exhaust currently on the car is 1" diameter, so I guess I'll have to get a standard one s/hand or built. What I'm wondering is - what is the standard diameter? What was the max size that the Sud used, did the 33 1.5s ever use a larger size? (I might get away with a 33 diameter, as long as it's from a 1.5)
thanks for you help!

Hi,
here is one of Italian exhaust makers, as far as I can see diam figures are factory ones.

if I remember rightly the standard diameter was 42mm
The 16v seems to be 50 and 48 respectively for the manifold and system, for info |
