When I installed another Carbonio intake from him in my '04 E46 330ci (M54) it was only a bit louder than the stock airbox, with the biggest difference and really only very noticable being above 5,800rpm.
I guess it depends on the engine, really. That and I could hear a lot more noise with a convertible with the top down than the much more refined E46 with an actual roof, haha.

I understand, but they are both E36's granted that one motor is the M50TUB20 (mine which sounds amazing) and the other is a M52B28 (my brother's with no difference in sound at all) it just doesn't make sense to me that one sounds so great while the other one is the exact same as mine but sounds exactly the same as it did with the stock airbox on my brother's. My only guess is that maybe the Intake tube isn't deep into air filter enough or that the flap in the throttle body isn't opening enough when accelerating.
