    Question Exhaust question

    truck is in sig 2011 ex cab 5.3, just purchased a magnaflow 24" case 3" in out muffler. should i dump the exhaust down, to the side in front of the rear tire or use the factory 2 1/2" tail pipe out the back? I have a concern that the factory tail pipe might be to restrictive.

    I wanna keep mine quiet as i have a baby on the way. Just dont know if the single 2.5" tail pipe will flow well enough or not.
