Pennsylvania's Vehicle Code, not Montgomery County, controls vehicle noise statewide. Every motor vehicle must have a working muffler with no cutout or bypass (75 Pa.C.S. §4523), and modified exhausts that amplify noise are illegal. Municipal codes add loud-stereo and motorcycle rules.
The Pennsylvania Vehicle Code requires every motor vehicle to run with a muffler in good working order and constant operation, with no cutout, bypass or similar device, and prohibits exhaust modifications that increase noise above permitted levels (75 Pa.C.S. §4523). This applies countywide and is enforced by state and local police. On top of it, municipalities regulate loud car stereos: Norristown bans any vehicle sound system 'plainly audible at a distance of 25 or more feet,' and cites motorcycles loud enough to draw complaints. Abington requires an appropriate muffling device and limits recreational off-road vehicles to 73 decibels at 50 feet.
Muffler and exhaust violations under §4523 are summary traffic offenses with fines plus costs. Norristown loud-stereo violations carry $50 to $300 fines and up to 30 days' imprisonment; each day is a separate offense.
