The excess air coming out of the ACV is useless right? So why not remove the relief silencer(16) and the air chamber(17). Is it a noise issue if so how bad is it? Are either of these devices necessary parts for proper engine operation? What does the air chamber do? I know the relief silencer muffles the noise of the purged air.

 

it sounds like many mooing cows

it's for noise.



the whole thing only weighs around 1-2 lbs. not worth taking out.



it's not fun to remove either.

 

Yeah...It sounds like a pissed off cow. Leave that **** on if you still have your air pump/acv
