In answer to your question: If it's a "shorty" muffler then it will be a lot louder. If it's the longer version then the volume difference won't be so extreme.
Now..... off topic......
Sorry, but not true! Yes, it will certainly be louder but it will also perform better.
It will only make it louder and you won't gain any performance.
Yep, and most of them perform better after modification!
Been tested over and over.
After seeing/feeling the result of my own OEM muffler mods and comparing them by riding other bikes back to back I am convinced that there are a lot of people with blinkers on in that regard!
If you want louder with more power you need an aftermarket
You don't need to spend money on an aftermarket pipe to gain performance! Careful (thoughtful) modification of a stocker (do your research!) will see your bike flying!
The only advantage in aftermarket pipes is looks (which I think 90% of people find the most satisfying, they look cool) and a weight reduction.
For the record an OEM Yamaha YZ450 "shorty" muffler is lighter than all of them anyway!
