I heard the one on the facebook page. Mixed emotions on the sound. Maybe I had my hopes too high that it would sound like a 60 series?

It is this truck, I posted up a video for Kory. The muffler that is on it now doesn't do much, the extra turbine housing will quiet it down quite a bit which is what I'm going for.

I swear you are doing the lords work with that thing. I just always loved the sinister/ominous noise from a Detroit 60 series. I had no reason to believe an I-4 would sound like that, I just wanted one fairy tale to be true.

That video was just a teaser with an iphone so it was hard to tell what it really sounded like, we'll have some higher quality video's up soon.

We've got it running with twins! It pulls in the upper RPM's now and that is where it lacked before. Where EGT's were 1800* on a mild tune WOT, they're now down to 1175*. We're just on a mild EFI live tune currently. The truck runs extremely smooth and quiet compared to the setup with the stock turbo and exhaust. I'm sure we can dial it in a bit more with tuning.
