Precision port.. how much is usable?

Whats a good way to cut the precision port down to size? Just a hacksaw for plastic?

PSP ports has said for a long time that you subtract .5" of usable port length from each flare. So, 18" long flared port is 17" of usable port length.

"PSP-4IF - 4" x 2 1/2" inside flare without mounting flange. Overall length of flare is 3" of which only 2 1/2" is usable because of the flare"

So, if the 3" flare has only a 2.5" usable port length, that means that .5" of the flare is not considered usable port length:

That will work. I cut mine with my table saw.

They’re pretty awesome and they fit together tight.

But my port should be 12.5" long with flares right?

Any round port calculator should work. All you have to do is add 1" to any round port length calculation. So, if you need 12 inches of total port length, then you'd need 13 inches of total length (with flares) for a PSP port.

You can use any port length calculator, and then you just have to add an inch to the overall port length, if you're using a flared PSP port (with flares on both ends). Just remember that each flare has 1/2 inch of it's length that isn't considered port length.

Awesome thank you Buck!
