Does anyone have any rules of thumb or better still accurate ways of calculating the volume of an exhaust silencer relative to the engine capacity, power and number cylinders?

Thanks hopefully,

Tony.

You to say I have been loaned an interesting book on this subject and now comes the interpretation and the design for my needs.

Are you managing to stay awake while reading it???

Its good for curing insomnia.

Why do I start getting very nervous when a scrute starts reading books on silencers????!!!!

Don't worry I am only looking at the pictures.
