is a new down pipe worth it?

So i built and installed my own stack set up. i used 4.5 emt conduit. I ran it from the down pipe to the bed and put 2 turned back stacks in the bed. all the bends are radial except i used 45* cuts in the bed. So my question is... hpw much of a benifit would it be to install a 4" down pipe insted of the factory one? Also where is the cheapest place to get a 4" down pipe? Thanks alot Also i use my truck as a DD once and a while a drag race or tow off.
