Those are spare parts, not upgrades. They are exactly the same as the exhaust valve you have in your marker right now and won't change performance at all. Just something you need if your valve wears out and needs replacing.
It's just like a battle zone, you got a bottle and you're on your own.
Gotta be a Scotch or a Kamikaze, none of those other weapons will faze me.
Hundred, hundred, hundred bottles on the wall, you wonder if you can drink them all.
Got to go home by 1am, the bottle wins the battle again.
