Where can i find a true dual exhaust system?

Well, you should be able to Google exhaust and come u with a few numbers to call in your area.

But beware of the "no cats" question. Are you in a state where they require emissions testing on cars back to 1999? What about trucks??

Find out the answer to this before you invest in a new exhaust system. It would be a shame to spend all that money and then not be able to renew the plates next time you need to.

You will most likely have to have an exhaust shop weld the O2 bungs in for you. Since it's illegal to remove the converters, IF they will do it, you will need to walk into the shop and ask them, not on the phone. They need to size you up to make sure you aren't a state/federal worker testing them. Trust me, for the up to $10,000 fine, your $500 exhaust job isn't worth risking it over the phone.

If you are talking to the exhaust shop, might as well have them do the whole thing. Not much to remove the cats and mufflers from the existing system, and terminate it however you want. You'll need to get rear O2 sensor simulators too.

Not a big fan of this, pretty stupid idea IMO, as removing the converters is absolutely pointless. It makes the motors drone and sound raspy, and makes the exhaust stink far worse than it would otherwise. No one likes that acrid smell.
