Greetings all,
I'm just restoring our 1750, and as part of this the exhaust needs
replacing, from the output of the manifold to the back of the car. At the
moment it's got mostly 45 mm tubing, with one muffler about the middle of
the car (it's not a straight-through muffler).
The car isn't too noisy, but it feels strangled. I think I should look at
2-inch piping with probably two straight-through mufflers, for reasonable
flow without being too noisy. It's a standard engine, and the car will be
used for fast touring on trips (no city use, and no racing.) We're Alfa
people so we don't want it TOO quiet. Just something nice for a sporty road
car.
Any suggestions on pipe size and the number of mufflers please? Am I on the
right track with the above? It's what we use on our 1700 Suds and it seems
good on those.
Thanks all,
Graham in NZ (GTV, 156, AlfaSud Sprint and TI)
