Cai diameter tubing and velocity stacks
Hey guys,
Anyone know what the pipe diameters are on the injen long tube or stillen gen 3 Cai's?
Also, I take it they use the small k&n filters due to space constraints in the front bumper but has anyone ever paired them up with velocity stacks?

The Injen are most likely 2.75 inch O.D. as the MAF section necks down.
The Stillen doesn't, so probably 2.5 inch O.D.
Also, a velocity stack does help smooth out flow at the inlet, but the largest gain comes from getting away from a straight cut pipe. The difference between a small radius and a large radius is pretty small.
