Hi Kim, noisy it is ...BUT,isn't it the coolest.... , to put your mind at ease,there is a add-on silencer/tailpipe muffler that just simply clamps on, should anyone complain further,inform them that it stimulates the animals into a breeding frenzy...... they can be a bit pricey,25.00 - 45.00$ US, but you can make your own....
