I was wondering about the Flowmaster 1 chamber mufflers..are they illegal? I wanted something louder than my 40 series but I don't feel like getting a ticket every week. I was just wondering b/c my local muffler shop carries these and reccomends them to me because they are slightly louder and perfectly street legal, the catch is..according to Flowmaster, the only 1 chamber muffler they make is for race use only..any feedback is appreciated.
