I know a lot of people thinking of buying and installing an HX-40 on their truck want to know how much it whistles. I'm about to take the 40 off of the truck, so I thought I'd make a quick video before I did.

The truck is equipped with 4" exhaust from the turbo back. No muffler. I just installed the black tip and everything last week. After shooting and reviewing this video, I realize there is an exhaust leak near the 45* elbow just peeking out from below the frame. IP has been turned up near max. Stock injectors. I don't have a tach, so I don't know how high the revs were. I'm not one to slap the truck around.

The black tip looks like it's angled weird: my camera has a 24mm fish-eye lens, so it distorts things. There are mud speckles on the black tip too- those aren't rock chips. Why do I feel the need to explain myself?

The wind was blowing and the truck is dirty. Sue me.

why are you getting rid of the 40?

 

let me guess.... it spools slow with the 18cm so you've been looking for a 16 but can't find one so now you're ditching the turbo all together? [lauhg]

 

It spools too slow with the 18cm housing and stock injectors and a 5 speed city driven 99% of the time. It's being replaced with an HE351 turbo off of a 2006 Cummins. It flows the same as an HX40 and has a 9cm housing (60/60/9 measurements). That should help significantly reduce the lag.

Yeah, who needs a turbo anyway.

(In my defense, the HX40 was on the truck when I bought it.)
