so i have been reading about tbs on the forum here and sounds to me they just make a lil more noise. which is fine with me really. anyone know what design makes better noise. or would it be worth paying 40$ compared to 100$
All you'll really hear is a high pitched hiss as the air runs through it and get no real gains. If you're still wanting to put one in, then a single hole with a helical cut one like the AirAid one would be a good bet. You don't want to get the 2 hole ones since the air flow throught the holes begins to interfere with eachother and results in a slower, more tubulent flow, rather than the fast laminar you want.
