so did all new exhaust yesterday. Have the eldebrock headers and y-pipe, Used a 3" collector at the end of they-pipe, Then 3"all the way back to a Big Dog muffler(F M ) knockoff. Then one 3" tail pipe out. It is louder then my pick-up with true duels.

 

true duals by them selves dont make a car/truck louder. Its just a different sound. the muffler, or lack there of, is what makes the sound louder or quieter.

 

I have 2 (40) flow masters on my 4x4 and a knock off single and it sounds better then truck. Its just funny how the knock off sounds better to me.My son wasn't home when I got back from the shop so he'll get to hear it today. It's his car.
