Not necessary. Doubt the headers would give you false knock on their own. +1 to getting it for cheap though. You might want it anyway if & whenever you do the H&C.

You ALWAYS want to add the LT4 knock module, ESPECIALLY when you do long tubes. The exhaust primaries amplify valvetrain noise increasing the risk for false knock.

I had some false knock i tried the lt4 knock module. It didn't help any. To fix the issues i had to go through my tuning software. I don't feel it was worth it, but it was worth a shot.
