I was trying to persuade you to dump the 3.0....... but if you must, just make sure you put the headers in before the heads go back on and I just used a cross over y pipe (NWOR headers) and a single 2.25 or 2.5 pipe all the way back. These engines aren't flowing enough to require duals and you can actually lose low end torque with too big of an exhaust. If they come with a y pipe it'll say it or cost extra, if it doesn't say it you'll need to fab one up. Another thing I've heard of is putting a cap on the one manifold and having an exhaust shop fab up an under the tranny y pipe using the stock manifolds. However if you look at your engine bay I think you'll agree to pay for the already engineered set up, I did.
