What would be the most effective size piping for a SOHC 2.2L accord?
Is 2 inches too small?
Is 3 inches too big?
....?....
What could work best....?.... btw... there's no turbo... I don't even think there will ever be a turbo on my car....

 

2.5 maybe? I don't even know what the stock size is.

 

Probably don't want to go over 2 1/4 otherwise you will start to lose horsepower and backpressure.

 

that's a good question btw....
...what is the stock size?

 

If not mistaken the stock size is like 1 7/8 inch it is just short of 2". Napoleon style.
