There's a one legged Canadian oilfield worker that's getting really sweaty 🥵 watching this.

A mid 1980s Bullnose dually with a diesel and a manual is LITERALLY MY DREAM TRUCK. I'm so jealous 🥺

I’ve always been a fan of the rectangular boom tubes that nascar ran in the 80’s to early 2000’s. Definitely an awesome sound that is no longer with us on the nascar circuit.

man, that sounds sweet! the fact that that engine sounds like a completely different engine in each gear / rev range is amazing!

I did duals and a x pipe on a 7.3 idi but not equal length and to be honest an idi person can pick up on the engine clatter pretty easy I do recommend advancing the injection timing it'll change the sound and have much better power

The clatter up front is the only thing that'll give it away anymore. Sounds really nice from the side and back. And it doesn't throw coke dust like some do LOL.

I think the new exhaust offers more airflow than before. If you take the 'hat' off the injection pump, remove the governor rod, you can get to the rotor plunger assembly. Once you can see that, roll the engine with a breaker bar, until you see a hex head screw. Insert a 5/32 hex wrench into it and TIGHTEN that screw 1/8 to 1/4 turn. That will increase rotor plunger travel, and inject more fuel, to take advantage of that extra air. You will be surprised with the increase in power, but more importantly, it will start much easier, even with a low battery or on a cold day! (don't give it too much, or it will "roll coal" at full throttle) If you remove the fuel line in the middle of the 8 injector lines, use that same 5/32 hex key, and adjust a delivery pump screw inside of the fuel inlet. Tightening that screw will increase the timing advance curve of the pump. Sometimes that adjustment is necessary, because over time, springs tend to sag. Once it's been readjusted, you shouldn't have to do it again, since the spring has taken its set. The rotor plunger assembly beds into the cam ring. Once this break-in period is over, it should hold this setting as well. It takes 12,000 to 20,000 miles, for the pump to fully 'break-in', then, it should hold its tune for the life of the pump, or perhaps, even the life of the engine.

First and boom tubes.

That sounds awesome! Now I want to hear it on a 7.3 and a 12V Cummins.

I had a 1990 7.3IDI, my dream was to install a 6-71 blower, long tubes and a moose pump on it. This exhaust would work with that concept excellently. A ZF5 would be a nice addition too.

Least it will sound fast😂😂😂

That's a proper exhaust, from the front only engine sounds and from the side/back you hear exhaust mostly, top notch work!

love that 2 tone white and red man beautiful truck and sonds great good luck with it bud

Thanks for showing the old IDI some love! I bought one last year and am just finishing a full exhaust build on mine. I just did a 3” y pipe with straight thru perforated muffler. They are great trucks!

Nothing better than hanging out with the buds wrenching on cars and trucks . Good job you guys 🇨🇦.

This is honestly the reason I still love driving the old 6.5s. I have always wanted an x-pipe twin turbo 6.5 😂

You do a great job promoting your sponsors. Your explanation of the versatility of the Blaster products and your real-life experience using them gives a valuable endorsement for the products. Definitely see you as a great brand ambassador and I hope they appreciate your enthusiasm and continue to support your channel.

Love the widow makers. I have them on my 65 F100. I like the higher pitch tones the mufflers bring out on that diesel. Sounds sick!

Excellent work guys! When i was a teen, we took our 1086 F250 diesel 4wd and created a custom single barrel type exhaust under it for about a year. The exhaust hangers kept breaking in the stock system with glasspacks. So the custom muffler shop mad us a joied tube into a 4" outlet that ran wide open out the rear. Ford THUNDER that truck was. LoL!

Went with true 2 1/2 duals with magnapacks on my na 7.3 idi, sounds like a hi compression 460.

That's so unique, and cool!!! Good video!!!

Love the videos man! Keep slayin!!

Back when these old non turbo diesels were new people dualed them out all the time and they always sounded pretty close to a gas burner just deeper whether they had glass packs or turbo mufflers.

worked on a lot of those defiantly the best sounding one i have ever heard nice job

It is absolutely amazing how one exhaust change made this sound like Gator McClusky's Custom 500 at a distance. Well done.

Yes, the famous hi rev run of the F-100 that blew the motor. It did sound good though.

I going to say that the manifold size is the for compression and back pressure to get the engine ratio at 22.5 to 1 without looking it up. Worked on tons of them in the last 40 years now. Can't wait to see how it sounds and runs after the new exhaust system is on. Good morning and enjoy your day today.

Watch it. Every time Craig does exhaust the engine goes boom..lol

Nice job Craig and company!! I'm really not into diesels but that one sounds pretty cool. Was there a power or milage differance after the exhaust install?

When I was working on square body chevys mainly I’d take pb blaster and spray the rollers and tracks on the windows and it’d help automatically same with 70s to 90s fords I believe

Well done! I dig it! 😊

Now I want an IDI dually with black widow exhaust! Thanks. LOL Great work as always.

Stoked for the new 4" Blackwidow mufflers. Ill be impatiently waiting the release date!

Glad you were wearin the safety squints while welding! hahaha

Love that truck!!! Sounds great!!

Between your channel and Black Widow, y’all have turned me (a GM and Cummins guy) into a fan of how Fords sound lol

This solidifies my plan to build a decent exhaust for my '84 dually, and then supercharge it rather than turbo. The only thing that would make that exhaust note any better at all is blower whine 😁

It will sound insane under a full load of pulling a heavy trailer.

Sounds Awesome 😎👍

That’s definitely the coolest sounding IDI I’ve ever heard. Pretty cool.

Good fabrication anyway, nice cars all around that place. I've got a 97 f350 4×4 srw with a 7.3. Inspirational video.

3:00 My parents still have a 1 gallon metal container of it in their garage, must be 20 years old, still works. Not to mention spray cans of it in the tool boxes of their trucks... they also work good as wasp spray too in a pinch. Just don't inhale when you spray lol

Nice team work truck sounds amazing !

Cool truck ! Sounds great.

I’ve been going back and forth on a 6.9 but I’m sold, this is perfect

This is the best content!

Damn, that truck sounds nice! On my 1st gen Cummins '78 Bronco I run a modified 3" downpipe into 4" exhaust with no muffler, exit behind the passenger door. It sounds nice at WOT, lots of whistle. But that's due to the big turbo on it. Without a turbo, the 7.3 definitely sounds like a gas engine.

Sounds great frenz. Good job

That sounds good 👍 great video

Black widdows sounding good!

Job well done gentlemen.❤

I have a 92 crew cab duelly, but I put the 6.9 from my 84 in it, I call it the beast, with the 5spd it's unstoppable.

I love that truck man!

Seriously. Black Widow Exhaust makes some absolutely top tier products. I have a dual in dual out 250 series in the custom dual side exit exhaust on my 370Z. I may be biased but I've never heard a better sounding VQ. and my exhaust exits in the same place too, right in front of the rear tires.

man Sick truck! From a distance, it almost sounded Turbo'd.

That sounds awesome! I wish that muffler existed when I helped rebuild my cousins 6.9 250. We put a stock rock auto unit in it.😢

Sounding good and the Mustang is still looking good.👍

That sounds great, good work brother 👍🇺🇸🤘🔥🔥

Peg would be proud💪💯

I think you and Chuck Seitsinger from the 405 should have a badass off.

Ahh makes me miss my old 92 7.3. Was also muffler delete, turn downs right under the cab. Shift into 3rd going down a hill and it sounded like it had a compression brake lol.

I remember X piping my '87 Crown Victoria with the 5.8l 351W. That car sounded sic. I miss that car.

I love this with all my heart

Reminds me of the cat 3208 in our cat 613A scraper! Great work guy's

I wonder what a diesel would sound like with 180 deg. "bundle o' snakes" headers!

Now that is a beautiful truck

Hell yeah! She sound good. I thought my straight pipe 5.9 sounds. She probably sounds even better in person

Real cool sound! 😃👍

As soon as I seen the bullnose in the thumbnail and the title say diesel I already knew I’d like this video, long live the IDIs

Buddy has a 88 swb Chevy with a 6.2 Detroit stuffed into it. It used to have super 10s on it and sounded very similar to this. Now it's got 3 inch and a massive tip and trumpets real bad 🤮. Cool sounding on that ol 6.9 🤘

Wish I had some friends like you guys

Would love to hear it on my Ford Ecoboost. Love this channel.

That’s sounds alright it will be interesting if he gained any hp due the exhaust scavenging from the x pipe Just gotta find a 6.9 idi with a h pipe and see what that sounds like

Michael's truck is probably one of the cleanest idi's out there

great stuff thanks

A turbo IDI is actually quite reliable as well if you add a aftermarket kit, my dream truck.

Should have built a set of custom long tube headers for that sucker..

I have the 1987 version of that truck it’s loud and slow and I still love it

Sounds epic guy's. 👍🏻😜

Mercedes OM606 owner here. Nice job! Sounds great. Maybe 180° headers will improve the sound even more?

It definitely sounds great, looks great 😂and its a rare truck&engine now adays

Love that Indy shirt! Old school cross too 🤟🏼 Hell Ride

There's a company that makes long tubes for IDIs. It needs some of those and the fuel turned up.

It was the safety squint for me when spot welding the down pipes lol! Been there.

Sounds good 👍👍

Sound amazing

Im a big PB blaster guy myself !!! I love it !!!

I think it sounds really good. I like it because it doesn’t sound like everything else on the road.

so I can remember 25+ years ago my dad building custom exhaust and making custom x pipes for lots of different things but a diesel is new 👍

I have the same 6.9 idi and now I wanna do this to my truck now 😂

Toby is the Mikey of American choppers

Had a 92 single cab dually with 7.3 idi and a 5 speed it was a awesome truck

Your truck sounds so wicked I ordered the same exhaust for my 15 f150 coyote 6 inch lift with 37/20/13.50

Sounds good

Thats one cool Ford F250. Sad that I dont live were you guys live because I own a 1994 GMT 400 6.5 Turbodiesel. If we could meet together with all three trucks we had a F100 NA Gasoline a F250 NA Diesel and a GMC C2500 Turbodiesel 😄. Greetings from Germany👋🏻

10:48 🎶come with meee, and you’ll beee🎶 in a world of OSHA Violationss🎶

Sound similar to a V8 IVECO. Very nice, boys ! Well done ! 👌😊👍

My dad had a 79 f350 with the 400. I don't think there was a good reason but he put one of those blackjack header and exhaust kits on it. It was a manky work truck. The mufflers did fuck all. You'd set car alarms off quite frequently just idling through parking lots. Late 80s era car alarms, but still. It was a truck with personality. It didn't like distributor gear roll pins, so it would shear one of those off about once a month. We got really good at fixing that on the roadside. like 10, 15 minutes... After an engine rebuild, the carb linkage didn't quite work right, particularly the accelerator pump. The fix for that was a pull string attached to the accelerator pump, from under the hood, through the wing window, secured to the wing window latch with a little loop. When you accelerated, you give the string a little tug, otherwise it would not really stall but it wouldn't really go either.

Peg would love this sweet heart!!👌👌👌
