A Serious Turbo Whistle, GOT SMOKE???????????
My 2004 6.0 Letting Out A Little SMOKE... SCT BABY GONE LOONEY...
How a 7.3 Turbo Sounds Under the Hood
7.3 Diesel Excursion with No Muffler!
This is after we took the muffler off our 2001 Ford Excursion with the Powerstroke 7.3 Diesel. Sounds much better! I thought it sounded good even without the muffler, Now I would never go back! That diesel growl and whistlin' turbo is a perfect combo!
