What does "muffler or other noise suppressing device" mean to you?
 

Got a copy of the Pennsylvania DMV Inspection code.<br><br>turns out the book is stating that a &quot;Muffler or other noise suppressing device&quot; must be present and total decibels on a hard surface (highway) under load may not exceed 92 decibles.<br><br>The book does not define or give examples of &quot;other noise suppressing device(s)&quot;.<br><br>this is legal<br>if this is the line -----------<br>this is illegal<br><br>and this is me x<br><br>this is what I am thinking <br><br>x x x x<br>-----x----x------x----x<br> x x<br><br>I am walking the fine line if I remove my muffler unless someone has information on what a &quot;other noise suppressing device&quot; is.<br><br>Think I am going to call the local inspector offical to get a ruling.<br><br>

A good flow thru muffler mite work....but knowing PA's inspection standards I am sure they will not pass you without a muffler in place...most PA inspection mechanics insist that you have a muffler on and that your exhaust system dont have any leaks

I use that very same muffler and it has a nice sound to it ithout the nasty resonation in the cab. It knocks out the raspy sound that will get you pulled over.

short enough to make two transition pieces.<br><br>I have snow under the truck now or I would go look.<br><br>I think the factory muffler is between 36 and 40&quot; long? That would give me two 11&quot; pieces.<br><br>I wish the factory muffler was a straigh through rather than offset. It makes conversions like these such a hastle.<br><br>

I like my clamp on muffler. Clamp it on for inspection, remove it when finished. ;D
