Yeah - w/o a doubt the intake is insanely loud, if ya think about it it makes sense - not only is air RIPPING through the thing, on a two-stroke if you peer through the manifold you can see the piston. Obviously this means there's gonna be some noise.
Ultralight airplanes are mostly two-strokes, mine had a Rotax 440 and the intake was FAR louder than the exhaust, even louder than the prop roar. I bought an intake silencer and all of a sudden I has a stealth plane!
It's a shame there's no readily available intake silencer for these kits, but the concept is simple enough. Here's a diagram of the one I had, even if it wasn't way too big, I wouldn't recommend buying ultralight parts - they're crazy overpriced.
However from that pic you can see the potential for making one yourself, I'd be on this project except I have NO clearance at all near my carb... ah well, mebbe someone else will get an idea
edit: Haha, oops... sorry to jack the thread, I didn't see there was a second page already *blush*
nothing to see here - move along
