    I've got a Bassani ORY bolted to the SLP Loud Mouth catback. But, seeing as you have to deal with emission laws there, you may have some problems.

    Here's a few clips.

    You're welcome and thanks. The ORY is technically illegal here too (I believe) as it's an off road y-pipe not meant for street use.

    Technically Long tubes are illegal in all 50 states. Any relocation of the cats (lts do this) violates fed emission laws. Only question is do they do a visual inspection of the exhaust where you live. In Md they only give you the OBDII test. I pass with Lts, no cats, no air pump/pipes, and a huge lopey cam. Definaetely not legal tho. I hope Illinois is more relaxed with their emissions then their gun laws. LOL.

    I am an emissions inspector in Utah on a 99 your car would be a obd2 so they just hook a wire up to your car and run codes basically, but the downfall is is that there are to do a visual inspection of your EVAP system AIR injection EGR valve gas cap PCV valve and the worst cats and o2's if you go to a dug down shit shop privately owned im sure you could slip the inspector a twenty or something to not look under the car haha but might lose 25 bucks paying for the test cause he doesn't take it haha

    About the cutout... I am from missouri and they told me as long as the cut out is closed then its legel becouse its all going threw the muffler. i know it sounds dumb. when we get inspected they just hook it up to a computer and if it reads your cats your legal.

    they used to be crazy like that unitel people starting complaining that it was a waste of tax money. so now that just plug into your computer. 98+ cars only have to do emissons.
