Message: [QUOTE="KrisH, post: 676339, member: 11132"] Hey folks, I'm planning on running an aftermarket exhaust system along with a DPF delete on a Super Duty I'm building this year and wanted some input and opinions on my options. On my last truck, we ran a custom-built straight piped side exhaust with a DPF delete. It sounded insane, but it was a PITA to have fabbed and now I'm seeing more exhaust kits coming out from AFE, MBRP, etc. I'm noticing they have muffler options. What does the muffler cut down on? Overall loudness mostly, or does it cut down on the howl when you let off the gas? These trucks sound wicked opened up but there were times when I wouldn't have minded a slightly toned down sound. Do the mufflers even make a difference with a DPF delete on the truck? If someone's got videos that'd be awesome, but just some input would be much appreciated! Thanks in advance, Kris [/QUOTE]
