Right! Subbed

One cut and it was out slicker than snot. THANK YOU. Minimal trimming on the pinch weld on my 94’ 4x4 5 speed. Best down pipe video on YT

[@rednecktech82]

Thank you, I greatly appreciate the support!

[@seijirou302]

I saw no less than half a dozen hack job videos before finding this one. Thanks.

[@jtdouglas9535]

Just came across this absolutely the best downpipe video out there for the OBS 7.3 I wish I had watched it before doing mine.

[@banderson7164]

You just took the scary out of it thank you.

[@Nfscarbon07]

Just bought a 94 powerstroke, love the truck so far and saw this mod, keeping the truck basically stock, just adding a CAI and this downpipe to help the old girl breathe a little better, thanks for the video!

[@rednecktech82]

Best 2 and the first 2 I'd suggest also!

[@alexlucero7383]

I was dreading doing this mod, as soon as saw your video you gave me the motivation to do it!! You are absolutely right, minimum time and fairly easy and fast to do. Grasias amigo

[@csedan510]

Way to take the mystery out of it. Great video with nothing but the facts.

[@JohnBoyDeere]

Bravo sir! As straight forward as it gets, many thanks!!

[@rednecktech82]

Thank you. That's my goal with every vid, try to be as detailed as I can without the meaningless BS n chatter. 😏

[@RUSTYCATMAN]

Well done! Thank you

Awesome video straight to the point

Really helpful video thank you sir

Great DIY video

[@journeyanders]

Bout to do mine today

[@robertf6523]

95 drw 2wd zf5.. had a bit of trouble getting diamond eye 2pc 3in downpipe on from the bottom.. had already tried everything from the top, AND my truck didn't have the pancake factory 💩 it already had a two piece 3in downpipe. Like oh hey surely another 3in will go right in there. The old 3in round 2pc downpipe finally gave up after cutting the top bend off. And the new one went in with some LIGHT persuasion via 3lb sledge. But the vice grips that were carefully placed on the bottom of the top piece caused burrs.. nothing a flat file couldn't handle. Firewall was already massaged without a hole through it.. and new downpipe is in, from the bottom. 👍

[@diamondeyemfg]

Great video!

[@bearfoxx1]

Video gave me hope

[@donsylvia842]

great video!

[@Impuritan1]

Glad I found this video. Ordering my “off road” 4” system this week. Nice truck btw.

[@rednecktech82]

I run a few OBS so always something new coming! Replacing core support in 90 minutes WITHOUT draining or removing radiator next!

[@Impuritan1]

Still haven’t ordered mine, life got in the way. But looking at the one I’m wanting, the specs say it won’t fit a truck with dual tanks, which mine has. I can’t figure out why it won’t when it’s on the opposite side of the truck. Does your truck have duals?

[@rednecktech82]

No duals here.

[@lintsausage]

dood morning, did you post that core support video? I can't find it

[@rednecktech82]

@@lintsausage No not yet. We are just coming into our muddy disgusting mess that is the spring thaw and I'm too poor for a nice big garage yet so I need to wait a bit...hopefully in June.

Love the video, doing this job now. I am always down to use a sawzall.😂

[@truesyn1]

wow, nice video.

[@rednecktech82]

Thank you, I appreciate the support!

[@jakefuller79]

Best damn video on youtube

[@sidescrollin]

I ended up not cutting anything. Hammer down on the edge like you said and then pushing in from the bottom. I can't believe so many other people pull off the insulation and cut the car.

[@killacali4283]

For anyone watching this. You don’t need to use a pry bar or hit your firewall with anything. All you need to do to get the down pipe in is get a jack and put it under the transmission and un bolt the the crossmember of the transmission from the frame and lower it, it’ll stop once it leaning on the turbo against the fire wall and that’ll give you enough space. You just put it in the top and give it a little persuasion with a mallet and it’ll fall right in. I’ve done it on a few trucks. And if it’s a manual you have to take the shift of because it won’t let the transmission drop far enough. Also forgot to mention. His new down pipe is extra long. I use one from diamond eye and it half the size of that. But I get it with their 5” exhaust. Item # k5314A I get it from SUMMIT Racing

[@eric26delta]

I unbolted the trans support and lowered the tail of the trans about 2 inches. The new down pipe went in from the top and no need to cut fire wall shield or bend it back works for me,

[@moeriou8431]

I did it this way on my 96 zf5 but it’s jammed between the trans and the firewall so it vibrates real bad. Gonna have to go in and massage the firewall.

[@rednecktech82]

There's been a lot of feedback on this, I don't know why but it seems some can get it in w/o cutting or trimming anything where others have no choice. I wouldn't think the kits would vary that much and the engine/trans setup should be the same!? Who knows.

[@Furious_George]

Do the up pipes next!

[@ericnasset47]

Great work brother. What brand down pipe is this?

[@rednecktech82]

MBRP? Any aftermarket 3" will be the same 2pc design with same install procedure.

[@brandonmiller7360]

Thanks sir, loved the video. In need of a little more advice though. Not sure but do you know what is the best deal on the 3"downpipe? I found one on the Riff Raff diesel for $129, I believe if I remember right that's before shipping and tax. After further research, I found 1 on Jegs for $97 like $122 after shipping + tax. Not sure a guy could beat that but curious if anyone knows. Just wasn't sure if there's a cheaper option even though I know that's a damn good deal? Thanks for the great video! I'm sure you saved a lot of people a shitload of time on this once dreaded job lol!

[@rednecktech82]

No you're right on they are all the same design and everything so just go with the best price you can find.

[@ericb8030]

I've done this on both auto and manual. The manual does have a little more room.

[@rednecktech82]

Thanks for the info!

[@prescottwidly5006]

Howdy, How has the aluminized steel held up for you? I’m considering the extra money for stainless for longevity. What are your thoughts? Also, have you had any issue with the hanger brackets? I also considered getting these welded rather than clamps after I have installed. Thanks for the very helpful video, I now feel comfortable giving this a go.

[@rednecktech82]

I live in salty winter road country, that being said aluminum will surface rust faster but I haven't owned a vehicle long enough that it rotted through. We typically get at least 10 years before the stainless starts to rust. So to answer your question stainless does seem to be more durable than the aluminum but if you don't plan on keeping your vehicle for more than 10 years save money and go aluminum because you'll get 10 years out of that as well. If you do go stainless there are also different grades of that, 409 versus 304. 304 is much more expensive but also has much higher resistance to rust. 304 is hard to find though so most parts you will find are the 409 stainless. I personally go with stainless over aluminized and have had great luck on vehicle's I've owned as long as 10 years after installing stainless... Again, never got to the point of needing replaced a second time.

[@rednecktech82]

As far as brackets I haven't had any issues with regular hangers with the stainless clamps that come with the SS exhaust kits for diesel. I'm not a fan of the U bolt style clamps you put on regular gas vehicle exhaust, they seem to always leak. I weld my exhaust on my gas vehicles.

[@prescottwidly5006]

@@rednecktech82 That all makes sense, thanks for the info. I have a 97 F-350 7.3 and this will be my first time ever installing and exhaust. I like the mbrp product, but they only sell a stainless kit that includes an exhaust tip for $685. The aluminized steel is $485 so a pretty big jump. The tip seems unnecessary for me especially with this being a work truck. I live in SW Montana so lots of snow and ice here as well. Do you think the stainless would be worth the extra $200? It also comes with a lifetime warranty which honestly I am not sure is necessary. As far as the hangers I’ll plan on just using those.

[@rednecktech82]

I personally wouldn't pay $200 more for the stainless, it doesn't look any different/nicer. Again if you plan on keeping the truck for 20 years then maybe. Lifetime warranty says a lot about the quality of the product but when it comes down to it every company has a 100 different ways to get out of actually covering anything so I wouldn't bank on it being a true lifetime warranty.

[@davidjones3841]

Have you noticed any difference in performance etc in otherwise stock 7.3, or does this only benefit larger injectors etc?

[@rednecktech82]

With JUST this "mod" you won't physically feel a huge noticeable difference but it does definitely improve breathing for the engine and turbo and sets you up for a nice CAI, exhaust, tunes and other improvements.

[@h2ohfowl408]

Is that a straight pipe? To what size exhaust tip? Looking at options for my 97

[@rednecktech82]

4" straight to 6" tip

[@woodsrodi1054]

Where would you need to apply that anti-seize if your redoing the exhaust

[@rednecktech82]

Downpipe flange and I put them on exhaust clamps just to help with future removal if they rust.

[@professionalredneck7920]

Dumb question. Do you need to have a tune to get any real benefit out of these 3 inch down pipes or not? I'm getting ready to do mine, but if I need a tuner (which I dont want) for any significant improvements I'm questioning whether it's worth it or not.

[@rednecktech82]

No tuner needed, the benefit comes from the much better air flow this provides over the stock pipe.

[@rednecktech82]

Tuners are only absolutely necessary on 2010+ diesels that have emissions like egr's etc. When you go to eliminate EGR's and things like that the tuner turns off any codes that might get tripped by the trucks computer.

[@yogib7603]

What year, and what transmisson is your truck?

[@rednecktech82]

95' ZF5

[@eukiakaczmarek7132]

My truck blows quite a bit of blue smoke. Not sure if it’s really oil or diesel. It’s my first power stroke, would the truck smoke more with a straight pipe? My exhaust is still stock.

[@rednecktech82]

No more than it already does.

[@kjmerritt3851]

What do i do if i cant get the wall to bend

[@lilhalfy]

If it's burning your eyes that would be diesel

[@hockeh9230]

Will this work with the E40D?

[@rednecktech82]

If I remember correctly others in the forums and things have said yes it's about the same as far as fit around the bellhousing goes.

[@Motoman714.]

What company was this from

[@rednecktech82]

Links are in the video description for all the parts and supplies I used.

[@nickroberts4586]

So do they make 4 inch down pipe though?

[@rednecktech82]

Not that I am aware of and if they do you would definitely have to cut then.

[@travisengland3306]

Getting ready to do one for the third time first 2 were a pain in the dick. I did a little like you on my last one n also learned that it has to be feed from the bottom. Gonna try your way hope I get it done n an hour. Still got Injectors to swap haha

[@felixwankel3989]

OEM's really just dont fucking thing when designing most vehicles. Stock down pipe on the 7.3's are a travesty.
