I personally wouldn't run the 3" exhaust on a non-turbo car. It's just too big for use with a NA car. I would expect a very noticable loss in torque with a 3" exhaust on a NA car. Buy a used cat-back for a couple hundred bucks from another member here for now, and put the 3" system on when you get the rest of the kit together. Then turn around and sell the used cat-back. I doubt you'll lose more than $200 if you shop around.
