Sudden power

[velardejose]

Hi
Suddenly my mb got more power and made lots more noise
My muffler internals fell...
I could get it and the screw didn' t fall
Engine has pore power, but noise is intolerable
Hope to reinstall it later
Peace

Yes... they do get a lot more power when you unblock the exaust!
A good compromise is to drill a few 3/8" holes into the end of the pipe & through the baffles. (a little more noise, a little more power!!!)
Just find a good noise to power balance that you're willing to live with.

Leave it off!

noise will get the neighbors mad at you and kill the motor assisted bike thing but that is up to you. I know in Ca. the leaf blowers are something that people really hate wakes them up in the morning.
You boys and girls that like loud things need to consider the neighbors and who you are making mad, they might be the lawmakers and will outlaw your bike with an engine I'm sure its coming.

Good point Norman. When I go for a ride, I always pedal my bicycle out of my neighborhood until I hit the main street.

Me too
I reinstalled the muffler internals as it comes from the factory
I was tempted to open the tube but the noise thing and how much power would I gain made me leave it alone
Peace
PD It is better to get grins from your neighborhoods, not angry looking faces...

a few extra holes might be nice...more power, grunt!

Cut the tube that is welded to the muffler end cover. The noise doesn't increase a whole lot, but you'll notice some power gain.
