Some recent sound clips I took since I recently put in straight pipe.

The two files with "hill" in the title are straight piped. The turbo file is an older one thats been in there a while.

The 5.9 UPhill is I clip I took where there was a brick wall on the passenger side the entire way up.

The winding hill file is my favorite, I'm going up a winding steep hill and the engine has varied power output and throttle settings. Sounds really good.

There's nothing like a straight piped Cummins

Needs a little more turbo noise though

 

Yeah, the turbo whistle didn't come through as well as I had hoped. Maybe next time I will strap the cammera in the engine compartment next to the intake. I bet that would sound good.
