Mopar Hotrod Truck :Hedman Hedders and Custom Exhaust! Project Juan Carlos

This is a full install and review of the Hedman 79080 hedders and homemade custom exhaust. The mufflers being used are Dynomax bullets. This is a stock 1991 Dodge D150 with 318 TBI. I show the new positioning of the 02 bung and how to plug the 302 head smog ports. For More information view ‪@318willrun‬ channel.

Thanks Brother. If mine, I would have switched to some 18" glasspacks. It really wasn't that loud in the cab, even without carpet or insulation.

[@blah9664]

You did a good job on that. I've got the same headers waiting to go on my 87 d100 318. Good to know they fit good.

[@JustMoparJoe]

Thanks brother! I believe the ideal setup would have been dual 2 1/4” pipes into an x pipe, and then ran into mufflers and pipes. The other option would have been into a Y pipe and into a single 3” muffler and single exit pipe. The 318 might have lost a little bottom end the way it is, but the owner wanted an exhaust that he could use with a high performance small block or big block later.

[@318willrun]

Nice job! This is great because I’ve been wondering about which headers to get for my ‘74 D100 and was planning the exact same exhaust routing. I gotta have more muffler than that though lol! I’ll get a mini starter if I have to, but how tough is it fit the stock starter? Looks like it would be really tight.

[@JustMoparJoe]

Thanks Ron! I believe I used the stock starter on the Red Sled when I put these same headers on. It was very tight. He switched to the mini starter not long after install.

[@DuddiesAdventure]

That is a nice exhaust system! The truck sounds great! And it rips! Great job on the exhaust install, very clean installation . I wonder if you can get those Dynomax bullets in 4", looks like they would make great resonators for a Cummins exhaust. Tough break on the oxy sen and header flange, That is most definitely something I would do!! ........and possibly have done.....

That’s a tricep and shoulder workout. Those things were made with railroad iron!

[@christianc2118]

I have exactly the same truck - 1991 d150 with 318 tbi and A500 transmission. I will pull out the motor soon and do a refresh - new gaskets, freeze plugs, paint, etc. The truck runs pretty good, small water leak at the intake manifold and one of the freeze plugs. I was thinking about converting it to carburetor, delete the emission and computer stuff and do the same long headers. But now I see yours still with tbi and running good.... Do you think what you did to this truck improved the drivability, power of the motor? Would you do a carb conversion to this one or just go with a 360 la carb all in?

[@JustMoparJoe]

The carb swap would probably net you more power. The TBI does have decent drivability and is quite responsive in this one. I believe the headers gained some torque. But carb swap,intake, cam, and headers will do the he best. If you’re not worried about mileage, then go 360 all in! Lol

No sir. This one was a bone stock cam. I believe you can go with a slightly larger cam, but nothing crazy. Maybe call oregon cams and get your stock one reground

Great video !!! I noticed that you did that right around the 6 min mark An said to self I bet that’s the mistake he’s talking about lol.. I even rewind it to make sure I did see what i thought I saw An sure enough lol !! Too funny 😁.. simple fix though ..that’s pretty close to what I about to finish up on my truck.. I got the headers all on with magnaflow high flow cats , An my header on passenger side came with 02 bung already in it .. an I also have a rear 02 sensor as well .. but I have yet to get my race bullets on An pipes I plan to run the same way u did ..did you not use a rear 02 sensor an where did u put the spark plug fouler in front 02 sensor Im guessing ?? An is that where I should run mine on the upstream/front ,not the downstream or ? It sounded real good !! 👍

[@JustMoparJoe]

So this truck only had one oxygen sensor. It was in the driver side manifold. I moved it to the passenger side. The big fouler was what I used for a bung for the one O2 sensor. It runs well. I felt like a Turkey after the flange 🤣

@@JustMoparJoe ooh ok I got ya now in the 02 sensor bung/fouler ..👍 An ya like you say we all do the darnest things lol

[@LilRedGarage]

Lol! The flange! I thought I had it figured out your mistake when you installed the headers without putting the starter in. I maybe mistaken but it looks like the frame on the driver side has been cut or shaved back for clearance? I am currently installing the exact same headers on my small block warlock and having issues just barley clearing the frame and mini starter 🤦‍♂️.

[@JustMoparJoe]

That mini snuck in on the side, without unbolting! I was shocked.😂

@@JustMoparJoe do you know what starter you used? Like mid to late 90’s ram/Dakota?

Cool truck! I scored the one from a few weeks back.

[@bobbyz1964]

Never made that mistake. I mean that particular mistake. 😂 On my 66 Volvo wagon I upgraded from a straight 4 speed to one with a Leycock De Normanville J-type overdrive. (Gear Venders units are based on those) Somehow I got through the engine build, a B20 block from a boat with car internal parts and went through the transmission and attached OD unit mostly mistake free. I'd never really seen any of that stuff before, so I was feeling smart. When I put the thing in I thought about hooking up the wires before getting the transmission in place, but didn't. Got everything bolted in then went to wire up the OD unit. There's two wires on top of the tanny for the 4th gear switch, that no matter how much I cut my hands trying I couldn't get at! Spent a few hours unbolting crap to tilt the engine back for two damned wires. But every thing worked and the only stain on the floor after the initial run in was my blood. 😂
