    I personally would leave the cats off.....at a bare minimum I would get new high flow cats.

    Factory cats restrict alot regardless, and 10 yr old factory cats restrict even more lol. As said above i would go with a ory for best results and sound if you can get away with it. If not some high flow cats will do the job..

    Put an electric cut out before your cats!

    OP,

    I agree with Orion, TN (unless it changed in the last 8 yrs) has no state inspection, so going with an LT's/ORY and delete the CATS will give you a good bump in HP, the cutout that is mention, will give you better flow, but not necessary a big jump in HP. Mostly just fun to have

    with a ORY you can put the cutout anywhere prior to the muffler. Common spot is a single cutout placed near the rear passenger seat prior to the exhaust tube bend up to go over the axle.
