Project: Selectable Exhaust

[CanadianDiesel]

Since I made my truck 4" straight-piped, I have loved it. The gains are obviously having a free-flowing pipe, but there are downsides. Loud trucks attract unwanted attention (noise fines), they wake sleeping neighbors, and they can sometimes get annoying at highway speeds.

While the 7.3 is loud to begin with, I want to install an extra 4" pipe that has a good muffler on it, and mate that to an Electronic cut-out. At the flip of a switch I can have loud (straight) or quiet...er

I will start collecting parts, and so far I think I'll be using Quicktime Performance for the cut-out part.

Should be a fun project, I also wanted to see if anyone else has done this on their rig

I have seen this for hot rods but never for diesels. Are you going to run new pipe all the way out or y it back in after the muffler?

subscribing, Ive thought about this as the drone of a stack in a regular cab is about enough to pizz off the pope cruising on the highway

I got cut outs on my Lightning comes in handy since it's louder then my 7.3 lol. At least at the exhaust end

there was a truck in a magazine that had a selectable stack that would extend when used

that was pretty creative

Its broken now, but I noticed no differance in EGT's or anything else when using it.

Sounds cool but thats about it.

And to be clear, mine broke after 4-5 years and he has offered to fix it, just need to pull it and send it off.
