    I had turn downs right off the muffler for a while and I think it sounded better but was just to loud at 5am. My neighbors probably hate me enough as it is.

    Ran out the back like in the picture I believe it is in the second post would be clean! Even if it's single 3". I've ran it in front of the tire on multiple setups and the only would that didn't sound flappy was my 3.5" 5x11x22" magnaflow setup I had on my crew cab. Others had any annoying flow master sounding flap in it. I'll post videos with details on the entire exhaust.

    Here's my setup, schoenfeld headers, 2.5 mandrel tubing, borla pro Xs mufflers and generic tips. Sounds pretty awesome, also I used V-band clamps for my joints.
