Tubing Question

I am looking to buy the HornBlasters Shocker Classic 228VX Train Horn Kit but before doing so I had a question about tubing lengths. If the length of tubing to each horn is different will the overall sound of the horn be distorted? I ask because I have seen a couple of people saying that the length of the tubing to each horn will make a difference as to when they actually sound when triggered.
Does this mean that the tubing lengths all need to be the same to each horn in order for them to sound at the same time when activated?

Thanks, MattS

You got it. It’s just to get them all sounding at the same time.
Figure out your longest tube & then make them all that length.
