If you can ditch the cat ditch it. My car passed smog tests with 3" side exit straight pipe so it's doable.
That's what I hear from most turbo guys. You want the best free flowing exhaust, as it helps with efficiency.

Re: New daytona owner

Grandsport2013, I went with the 3" Turbos Unleased setup. I put a 12" Vibrant Performance Bottle-Style Resonators 1792 where the cat use to be, and a 14" round straight through Magnaflow muffler. I added a turndown exhaust tip that matches right up to the bottom of the rear bumper. I don't experience any drone (but I drive mostly with the t-tops out), sounds great without being too loud (I was also driving a challenger with flowmasters). I did add a 3" swing valve too, so I cannot share exactly how much just doing the exhaust alone woke the the car up, but I very happy with performance and sound of my setup.
