My Camaro has the same exhaust as Ethanws6...But my first true duals that were on my ta were lt's, flowmaster 1-chambers, h-pipe, over the axle-didnt sound that good. So I switched it to lt's x-pipe, dynomax bullets, over the axle. That I liked and had up until the fire. Wizard, I would recommend putting the lt's and ory on with your flowmaster catback and see how it sounds. I wouldnt suggest running it over the axle with nothing because I have heard that on stock ls1's and its not that great kinda like a drone with no tone. When you get a big cam then its a different story
