remember if they try to pull shit about modified exhaust there is no such thing. the statute state you cannot remove, dismantle, or render ineffective any air polution control device or system ( unless you are replacing it with something of equal design or function), I.E. air injection system, egr, catylitic converter. since when is a muffler an air polution device???? the polutants that are entering the muffler are the same as those that are coming out, the muffler doesn't filter shit it just modifies the sound, therefore the muffler is not a polution control device or system and is not under the scrutiny of this statute.

the muffler does apply to the noise statute but where are the dba meters??? the muffler also applies to one of the other links that I listed earlier, about the fact that you have to have one, doesn't say you cant modify it ( gut the baffles) just that you have to have one.

so all this means is keep a fairly quite muffler ( gutted?) a cat ( who can tell if its gutted ) and the header and tailpipe. with that your system is legal.
