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.

How would you lose torque by lowering the back pressure on the exhaust side? If anything your gains between a 2.5" and 3" would be minimal since the 2.5" has been proven to be sufficient all the way up to 500 rwhp. Its all about flow, and only flow, make it flow better and you have less back pressure. Less back pressure less work the engine has to use to move the exhaust out of its cylinders and thus make more useful power.
