50cc intake manifold

Does a broken or leaky manifold make the scooter loud when revving up especually uphill?

Usually leaky intake won’t run well or at all. Pod air filters are noisy , but that’s on other end of carb kinda what you mean by loud?

Could be my tecnigas exhaust as well which was derrstricted but even though i just changed the packing it remains too loud like a dirt bike when i rev higher on the road. Or could it be that the snorkel on my airbox was removed making it so loud? Would it affect the power and performance if i put it back?

I bet it's loud because you changed the packing. The higher you rev, the faster the sound waves travel and they are basically scooting right past the packing making you hear it more.

I made a custom shorty muffler that's pass-thru (no baffles) and it's awesomely quite at idle and up to quarter throttle but when I go wide open it sounds like an open header with no muffler at all.

I changed the packing because it was so dirty and due for a change. I thought new packing on the silencer quiets the sound it emits.

2 or 4 stroke? I had a loud pipe recently that I repacked and it was still loud. Turns out there's 2 different kinds of packing, 2 or 4 stroke. The 2 stroke stuff is fluffier, the 4 stroke more dense.

When packed too tight or too loose you can have excess noise. Is the noise from the muffler end or the engine end? You may just need a new gasket. A quick video could help us determine.

Sounds like from the engine end. Yah i jave a new exhaust gasket i might just change it and see. The airbox snorkel taken off shouldn't make that loud noise like a dirt bike sounds haha.
