I did. That was in the earlier post before I painted it.

Downpipe is painted and wrapped. And now installed. So once again, the exhaust is done, for real this time…….except for the tip, which I will do after the bed is installed.

Probably so.

Oh no…I haven’t used a stock air box in years. I’m going to do another airbox like I did last time for this truck, but I think it’s going to have a different filter configuration this time. Post in thread '1994 K3500 extended cab dually'...

Got the passenger side heat extractor in. I did a quick coat of black paint to make it look more representative of the finished product. I’m quite pleased. It’s going to need just a thin skim coat to make the body work perfect, so that also makes me happy. Once I have the fender mods done, I am...

Yeah, plastic. I was thinking I’d make a mounting ring with hidden studs to retain it to the fender.

I appreciate the real world experience. I think I’ll be fine with what I’m envisioning. The chamber isn’t sealed, so water can drain. I will also be running an Outerwears sock on the filter that also keeps water out of the filter. I’m just trying to give fresh air an easier path to the vicinity...

I’m stoked. I think it’s going to be pretty rad, both functionally and aesthetically.

Next I started working on something I’ve been excited to get going on because I think it’s going to be really cool when it’s done. I’ve been wanting to do some kind of a heat extraction system to help get the heat out from under the hood. I didn’t want to do anything in the hood because I...

I finished up the modified mid pipe today, too. This is how much I had to jog the pipe around that brace under the cab to get clearances right, it was straight before….sheesh.

Final test fit before paint. Tons of heater hose clearance, which is nice and everything else fits nicely as well.

With the tight bend the cobra head allowed, I was able to step up to 3.5” diameter tubing. I used some 45 degree elbows and sections of straight to make a routing I was happy with. I have figured a tip out while making these pipes - I taped the joints together with masking tape to temporarily...

I got the downpipe rework done and it turned out really well. I had to trim a bit off the cobra head to make it fit the space I had. Interestingly I found that the main body of it is double layer and at the outlet there were actually 3 layers of tubing at the junction. I cut the factory turbo...

Thank you, sir!

I’ve been waiting for downpipe parts, so one thing I did in the meantime was make the turbo drain. I cut off the tube from the block drain and welded a -10 AN weld fitting to it. I also got a -10 AN stub for the turbo. Finally I made a hose using the same -10 braided hose I used for the oil...

TRICK OR TREAT!! This one is good until 10/31/25. 316920899253246176

Yeah, in hindsight it would have been nice to move it. I also would have leveled the flange the turbo bolts to because the stock 6.5 angle makes drain clearance more difficult.

Ummm…..more difficult than originally thought. First, I went out Sunday to get started. First thing was moving the truck over to my project stall. I don’t remember what got me under the truck, but when I did get under there I noticed I had more issues than just the downpipe - there was exhaust...

I’m going to mockup the core support and inner fender, plus put the AC line in place so I can truly see what my envelope is and then optimize the downpipe to fit. I’m still shocked how tight it is. I think the way I did the #8 tube ate into my space more than I understood.

Got the cab on today. Took longer than I anticipated, but the task is done. Unfortunately I found that the downpipe hits the cab - even when it’s detached from the turbo. I thought I was going to have tons of room with where I put it and have the best heater hose situation I’ve ever had, but...
