Will my Dirt Bike go faster with a bigger exahusts?

Hi i have a 50cc mini dirt bike that goes around 45mph
and i am just wondering if i got a bigger exhausts would my dirt bike go faster or just sound louder?

nope. exahust will just make it louder for the most part maybe add a few horse power but other then that no. if you get a lighter exahust then u might gain a couple MPH but on a 50 that little change in weight wont mean much.

i would put th money into the engine and then the suspension because they are much more solid investments.
