Installing 5" Exhaust and Tune on GMC Duramax 2500 | Insane Turbo Whistle

In this video, we do a muffler delete and install a 5" MBRB straight pipe exhaust. We also install a 80 H.P. tune from Same Day Tuning, using an EFI Live. The turbo sound has that whistlin sound now. It sounds so much better than stock exhaust. Can finally hear the turbo spool up.
