MBRP 4" Exhaust Install - Ford 7.3 Powerstroke Diesel

[@95Sn95]

A friend of mine just picked up a nice early 2000s Superduty dually with a 7.3 for a welding rig and it has 4" exhaust with nothing but a mbrp muffler thats outside diameter is not much larger than the pipe...like the O.D. of the muffler is like 4.5"! On a 4 inch pipe it's barely noticeable. it also has a aftermarket cold air intake. And it is not loud at all, it really doesn't sound a whole lot different than a stock truck...? are the 7.3 PS engines know for not having a very loud exhaust note? I've heard really loud diesel trucks and this is not one of them, what more could you do to it to have a nice rumble other than remove a muffler that's likely not doing much muffling anyway or is that muffler way more restrictive than it looks?

[@TheBTRGarage]

Going to a 5" exhaust will make it louder, if thats what your friend is looking for. And/or straight pipe it with no muffler at all. My truck, with the 4" exhaust and S&B intake, is definitely louder than stock and I wouldn't want it any louder. On long cruising trips the engine noise can get annoying to be honest.

Hi great vid I noticed that you put the egt probe post turbo which is ok if you have one pre turbo or don't have a chip/tuner on the truck but if you do have one you must have one in the driver's side exhaust manifold ask me how I know 😥 I love the content and you are doing a good job with the truck keep up the good work 👍👍👍

[@TheBTRGarage]

Thanks buddy! I do not have one in the manifold at the moment but I will look into that. The gauge instructions said it would be fine an inch or two from the turbo, hence the placement. Did you burn something up in your truck? Just curious what happened so I can avoid the same result if possible 😁

[@TheFordf350superduty]

@@TheBTRGarage yes I over heated the turbo not bad but it could have been real bad because you can cause the turbo seal to leak and then the motor will run away and it will not stop unless you block off air to the engine and if you can't then it won't stop until all the engine oil is gone 😬 most of the time you will melt the pistons first. But in my case the turbo was already weak so it just said no more which turned out to actually be a good thing because I heard it make a bad noise and stopped. Thanks Heath

[@TheFordf350superduty]

@@TheBTRGarage the egt probe being after the turbo gives a cooler reading than before so if you are at 1200F post turbo you could be at 1400F before the turbo.

Because of the muffler it is qiueter

[@user-dn6qy1ou1f]

Put the egt gauge in the manifold like the others say. You also want the probe in the center. And to not have wall material making the temp the probe reads be less accurate. Also, cut the pipe so that the tip actually makes a sound difference. What's the point of the tip when the pipe is near the end of it. And loose the muffler. It will sound way better!

The egt probe should go into the manifold. Putting it in the down pipe provides an inaccurate reading.

[@TheBTRGarage]

Yep, well aware of the difference in temp readings due to the location. I am going to re-install the probe into the manifold here soon and do a comparison on how much different the temps are.

[@adamwest2130]

Should have put the egt probe in the driver side exhaust manifold. To get real egts. I'm the down pipe your looking at a 4 hundred degree difference. So by the time your gauge reads 900 it's really at 1200

[@TheBTRGarage]

So I have fake EGT's? 😂 I've heard this from multiple people already. Even though I installed where the instructions said to install it, I will be moving it to the exhaust manifold to test it out. I don't believe there is a 400° difference but that's what I want to test and find out. BTW 900 + 400 is not 1200...

[@FreestylePYRO1]

I agree, The manifold probe is the correct way to get egts. Using the downpipe is not a true reading because it's after the turbo.

On the highway does this drone or is it OK? Jody at DP-Tuner that he needed to add a Corsa muffler on his Excursion to make long drives more pleasant. Also now that a year has gone by what happened to your MPG after the Tuner, intake and exhaust? One more question, did the location of the EGT work out, or should I drill into the turbo?

[@TheBTRGarage]

Sorry for the late reply, didn't see this! I'd say it doesn't drone much if at all. It is not quiet, but you just hear smooth V8 engine rumbling at highway cruising speeds. MPG did not change that much, maybe 1-2MPG while towing. What really changed was just the effort of the engine to pull loads and get up hills and inclines. With the stock stuff the truck was constantly chugging and downshifting on even the smallest of hills. Once the parts were on you could just hear and tell the engine was breathing more freely, rarely downshifting. EGT pyrometer works out fine in the spot I put it in, you just have to be aware it might be a couple hundred degrees higher than if you had it in the manifold runner (where most put it).

[@manninggrinnan621]

IMO leave the stock exhaust alone on these trucks except for maybe the muffler . These 4" slip joint exhaust systems are all kind of a pain in the butt to install and don't really do much for performance. And a lot of times they will rub and bang on stuff because of the larger piping and cause issues.

@@TheBTRGarage good to hear!

[@jayonez137]

EGT gauge Should not be installed in the downpipe. It goes behind the number 8 Cylinder on the exhaust manifold itself. You will be getting false cooler readings if you install EGT probe in the downpipe. EGT probe needs to be as close to the exhaust port on the head as possible. You are at least 200° cooler in the downpipe then you are in the exhaust manifold it’s self Just saying

[@TheBTRGarage]

Right, this has been beaten to death already in the comments :) The Autometer instructions tell you to put the probe right after the turbo, IF you cannot install into the manifold. I couldn't at the time, so for now it is in the downpipe and I am aware that the temps are going to be lower. That said, I WILL be moving the EGT probe into the manifold for a more true reading in the near future here. Stay tuned for that video as well as the comparison of temps between the 2 locations!

[@jayonez137]

Yup yup. Gotcha! But it’s also very simple To just lay on your back under truck and drill hole and tap exhaust manifold. I know it sucks but it would have been done right the first time. Obviously you have to do this carefully so you don’t get metal shavings in Manifold. A good dose of grease on the tap helps with that and shop vac with tiny computer cleaning attachments. Good luck man!

I just installed this exhaust on my 2000 Ford F-250 SD 7.3L Powerstroke. This video made it very simple. Getting the stock system out wasn’t bad. The bolt on the V-band was a booger to get off and some threads were jacked up but tap and die fixed that. Installation was pretty simple-ish. The joints were still a little loose even after torqued down (any suggestions???). Also, I added a black tip for aesthetics, but it seemed pretty heavy for the length, so I cut the pipe a couple inches so it wouldn’t stick out quite so far and reduce the torque/leverage in the system. All in all, it took me about three hours start to finish. Thank you for the great video!!! It made the job less daunting.

[@TheBTRGarage]

Thanks, glad the video was helpful! Are you talking about the slip joints being loose? You can always loosen them back up, make sure they are fully engaged, and re-tighten. I wouldn't worry about it too much though, unless it is an extreme situation.

[@theccwdad]

Thats thebperfect spot for a egt on that exhaust system. A little planning goes a long way drilling and tapping with that out of the car is the easiest best way. That pipe is thin did the threads hold up for you?

[@TheBTRGarage]

It held up fine there. But, I did end up moving the probe into one of the exhaust headers on driver side (3rd one back from the front). The temp reading on the downpipe where I had it originally is about ~200° lower.

[@theccwdad]

@@TheBTRGarage I wonder if that is heat soak in the piping. You want the exhaust gas temp not manifold temp and I would think that turbo outlet is the most accurate reading of what is happening. Downstream of all of the cylinders. They move o2 sensors on turbo gas cars further downstream to prevent fowling but up by the turbo is the most accurate reading.

[@TheBTRGarage]

@theccwdad Yea, that reasoning is why I put it right after the downpipe originally. But, you might notice in the comments several people saying that's wrong and put it in the manifold/header pipe 😁 I thought I'd do it just to test, so now I know what readings are in each spot.

@@TheBTRGarage How is 77 mph an optimal tow speed? That’s not efficient at all, and certainly not safe with a trailer load.

[@TheBTRGarage]

That's where engine RPM's, EGT's, MPG, and gearing is optimal with my truck and engine (when in a 75mph speed limit zone). If I go 70-74mph it hunts between gears, EGT's climb, and boost fluctuates. If I go even slower, it is not optimal again until about 60mph in 3rd gear. I'm sure it's different for different trucks. As for safety, I tow where I feel confident in the truck, and this truck easily handles that load at that speed. In my old F150, I wouldn't get anywhere near that speed because the trailer overwhelms the truck.

@@TheBTRGarage Would you then recommend waiting on the exhaust and focusing on the intake/tuner? Is there a specific tuner you used that you like? Again, I am not looking for hp maximization or to be ripping around town. Simply interested in efficiency and MPG increase.

[@TheBTRGarage]

@@prescottwidly5006 I would do both the exhaust and intake before the tuner. The engine needs to breath more efficiently, so those 2 things are recommended. Followed by the tuner, which efficiency is maximized by the bolt-on upgrades. I have a DP Tuner now, but would go with a PHP Hydra if buying today. In fact I'll probably switch to one soon. amzn.to/3CU0928

[@prescottwidly5006]

@@TheBTRGarage Thanks for the info and sharing your experience. I’ll go ahead and order this from MBRP and get an intake as well. Next step will be the hydra tune sometime down the line.

[@cajunman7389]

How did you come up with that location to install the egt probe? 9 out of 10 online videos show it in the drivers side exhaust manifold. Is the down tube a better location or is that just the location for a 7.3 not a 6.0?

[@TheBTRGarage]

That's where the instructions tell you to install it, there or the manifold. It also talks about the difference in temps and to be aware of that if you install into the downpipe. I will be moving it to the manifold at some point, and will test the difference in temps compared to the downpipe.

[@cajunman7389]

@@TheBTRGarage Thanks

[@stoveboltsix]

Any clearance problems with the down pipe and cab?

[@TheBTRGarage]

No, not with the down pipe. Towards the rear the pipe is very close to the rear shock where it goes over the axle. Other than that great fitment.

[@mikeprodanov7468]

Thanks for this install info.... planning on doing mine today. Identical 02 7.3.... got exhaust as a christmas present to myself a couple of years ago.... time to put it on! LOL I already have a Wicked wheel 2... look forward to hearing the turbo whine better

[@bobzippyify]

MBRP 4 inch straight is much better for the truck.

[@TheBTRGarage]

How so? Just because it doesn't have the muffler/resonator? I agree it is probably better straight piped, but I can't imagine it is very significant. The muffler/resonator is pretty short and not very thick.

[@bobzippyify]

BTR Justin don’t get me wrong it’s nice but if you got it tuned at all or plan to in the future it’s much better straight piped so the motor can breathe better. Even without a tuner you get a nice hp bump with the straight piped version. I got one on my 2000 7.3 and it’s honestly not that loud and it sounds good too.

[@wdenne]

Did you have to cut the down pipe or firewall.

[@TheBTRGarage]

No cutting of downpipe or firewall. Only cut was the joiner pipe near the back to fit it to your bed length.

[@wdenne]

Thanks again, my truck is pampered, doesn’t do much calling anymore. Just wondering if a muffler delete would help. Instead of putting a new exhaust. Plus it’s cheaper. Although a turbo muffler is basically a straight through anyways correct. Thanks for let me pick your brain. Bill

Hey Justin this is kind of off the subject did you see the article in Motor Trend Magazine about the new Toyota Supra

[@TheBTRGarage]

Of course! I did a garage talk episode on the new Supra a while back actually.

No worries, I will probably doing more episodes on the new Supra, actually. Very excited for that car!

That is one sweet exhaust system. Love that throaty sound. How do you get around the lack of a catalytic converter? I have a 2000 7.3L and here in Az we have yearly smog checks. They always look under the truck for that converter.

[@TheBTRGarage]

Thanks, I am loving it! The automatic trucks do not have a cat', there is a sticker under the hood somewhere that says no cat vehicle.

[@jr10]

@@TheBTRGarage Wow. Your state sounds like they're very diesel friendly. It is such a pain here to get that smog check every year.

[@jlg7798]

Have you had any issues with passing an emissions test now that it's installed? I ask because I am too a front range resident looking at adding that exact exhaust system to my 02 7.3. Thanks for taking the time to put out these thorough videos! Much appreciated!!

[@TheBTRGarage]

Nope, I've had emissions done twice on the truck and it is in and out. Passes all tests no problem.

Does anyone know if this kit will work on a 1995 7.3 powerstroke?

[@tjlqk3]

Cole Patterson no

[@jeremykeith3152]

You can use MBRP but it’s 3” down to a 4”back. That’s what I’ve got on my 95 PSD. It’s more difficult to install on OBS due to down pipe clearance

[@yurikfarba7169]

i thought the egr probe is to be installed in the exhaust manifold

[@TheBTRGarage]

That is the ideal location. The Autometer gauge says to install where I did, you just have to be aware that the temps will be a bit lower than if in the manifold. I will be relocating it to the manifold in the near future to test the difference.

[@yurikfarba7169]

how much lower are you suspecting the temps to be from the downpipe?... i have a 2000 7.3 excursion just received my MRBP 4'' exhaust and waiting on the edge insight with the egt probe to arrive so not sure if to just drill and tap the downpipe like you did or do the manifold

[@landonchase8134]

Feel any faster?

[@TheBTRGarage]

Not faster, but the truck definitely seemed less "choked" than with the stock exhaust. Felt like the engine didn't have to work as hard to do the same thing it did before (tow or whatever).

[@savvasstergos7175]

you got any advice, i can’t get the damn down pipe in

[@TheBTRGarage]

Hopefully you were able to get it installed? The downpipe is definitely a tight fit, but it does work. Just have to mess around with it for a while to get the right orientation.

[@savvasstergos7175]

BTR Justin yea lol just used stock down pipe and welded rest of pipe to it because it was vibrating really bad

[@ifishok]

Any change in MPG’s?

[@TheBTRGarage]

Not significant, I think I answered in more detail in a other reply. What is most noticeable is how much less the truck has to work when towing. It just moves air and makes power more easily.
