take off cats....no need fot them..run your longtubes straight to your exhasut and straight out the back..better flow, get different gears...maybe wont show on dyno horsepower but will make a big diff on strip..depending on what your doin with thst goat.!! bypass the throttle body coolent...run it stright into the block..but that pully wouldnt be a bad idea at ALL>> free up all those horses well maybe 5 of them lol

Apples to oranges comparison since the OP has a 2004 LS1. You started out with 50 HP more with that LS2.
