i didn't read the posts but there is NO legal limit for db's on an exhaust. it's called PROFILING. when i take my '67 ford galaxie 500 (2.5 in dual exhaust straight pipes) they never pull me over. i know the car is before the new emissions laws but they stop me all the time in my '92 integra with 2.25 in pipe with silencer, resonator, and muffler i get ticketed. bikes, jets, most trucks with straight pipes, and my other car (the galaxie) is louder than the integra. i just deal with it.
