Headers - primary pipe diameters Hi
Need to have some headers (manifolds) made up.
Looking for advice on manifold lengths, and diameters.
It will be side exit exhaust silencers.
Think that I want 1 3/4 inch pipes going into a 4-into-1 collector with a 2 1/2 inch outlet leading to my silencers.
Alternatively should I go for a 4-into-2-into-1 manifold. My thinking against this is, the amount of torque that the LS2 engine already produces, for my light RWD drive
The engine is going in a car weighing 700KG (about 1,543 LB).
The car is a road going car, but will also be used on trackdays.
Any help/advice would be appreciated.
many thanks
Kevin
