i was driving to work yesterday and i heard something that sounded a jet taking off.i looked over and it was a superduty. i looked to be a newer one.it was the loudest turbo i have ever heard. was it and aftermarket turbo or maybe an early 08'. anybody have any ideas?

it was the new body style.i have straight pipe 5" and i dont think it is a load as that truck. the turbo sounded faster than the truck. it was maybe going 10mph.

6.0's have some type of "valve" controlling exhaust gasses. When you put exhausts on them its like a jet engine. We did a 5 inch exhaust on a guy at steeda's truck and I couldnt believe the spool up lol and then it idles with a whistle and then the "valve" opens and it stops and then starts again so weird

It was probably an 03 they had very loud turbos with straight pipes. Because some stoooopid people thought it was too loud they changed the number of variable vanes for 04 and later. The 04's till now still have loud whistling turbos but nothing like the 03's.
