About the super 10 series flowmaster muffler?

i was planning on getting this muffler for my truck. 2000 dodge dakota 4.7 liter. but it says its not recommended on the road. is it illegal in california? or jus not recommended cause of the sounds. if its illegal, whats the charge? or the worst the police can do?|||It means you won't pass smog if it says illegal in California, plus most cops are starting to enforce laws regarding loud exhaust, you can and will be cited at least a fix it ticket then once again you have to prove you have fixed the noise polluting muffler that got you the ticket in the first place.|||that muffler is not illegal in California so it will pass smog the only thing is the noise. Not to many cops will take the time to pull you over for loud pipes because they have better things to do. Also if they were (cracking down) all these guys with their super loud diesles would be getting tickets left and right. Over all if a cop is board he will give you a fix it ticket but those super 10s are legal in california.
