Stock mufflers usually aren't very loud.
* An exhaust leak would make the bike louder. * Buying it second hand from someone who put a piece of shit performance exhaust muffler on it (instead of the OEM engine muffler), would make the bike louder. * Seldom mentioned in here, but a leak in the PAIR system hoses will also make the bike louder. * A leak in the air intake system, before the carburetor, will also make the bike louder. None of these defects would noticeably affect engine power, either (even the "performance" exhaust, on a 4-stroke machine they don't really impact engine operation). |

PS I beg to differ that a "performance" exhaust system doesn't impact engine operation! I built MANY a drag bike ( in NH) & I had time slips to back up my thought! We have a 15 MPH speed limit in the retirement community. |

When I first starting tuning 2 strokes I ended up with a loud expansion chamber exhaust. I didnt exactly conform to the neighborhoods wishes to "be quieter" and starting getting the sidewalls of my tires slit. Never caught the person(s) responsible but eventually put something more quiet on it, and parked it in the back of my van.

I have had good luck with just adding a street 70cc bbk and jetting to a pretty much stock motor, including stock exhaust, without to much more noise. Plus, the police in the know wont ticket you for a expansion exhaust. But, as always happens, I end up tuning it to get "just a bit more" out of the bbk. Believe it or not, but sometimes the intake system can be just as loud as the expansion chamber! Joys of a 2 stroke.
