Well a wile back I got a fix it ticket in my truck:thud: For "Muffler is to loud" & no mud flaps. I was running 5" straight pipe. When the cop told me that the muffler was to loud it was all I could do to keep from laughing and saying I aint got no uffler. But anyway I just put on a 5" core MBRP muffler and today after work I am making some Mud flaps with quick disconects so I can just take them off and put them back on when I need them. The muffler sounds prety good! its not to quiet and has a realy nice clean deep tone & you can still hear the turbo whistlin thru the exhaust:hyper: which I didnt want to loose. Every other muffler I have ran (Banks 4" & silverline 5") compleatly eliminated the turbo sound out the exhaust.
