Allthough it might not take away in power. Do you think its harder to hear the motor and know how its running? What about during a race?

More chambers = more walls between you and the sound. Therefore keeping more sound inside the pipe.

I heard the INS Box only drops the sound about 3db. I don't know how much db does the INS Box and the 3 chamber pipe combination when both being used. All I know the car is much more quite than before. When I use the INS Box I could still hear the motor when I'm racing. I haven't tried to use my JP Racing 2031 pipe yet so I can't tell you how much quiter the car got nor do I have the proper db equipment to give you the real reading in how quite it got from using the INS Box and the 3 chamber pipe at the same time.

Default 3 chamber pipe + ins box

The effect is reduced by a little but remember when you race with 10 cars then it will be quite a reduction. The sound is still there but it is not as loud becuase the ins box absorb the sound waves from the the carb inlet. A good device.
