I use to be a fabricator for rail road, and recently opened my own shop where I fab turbo kits. This video is 100% the best pipe fab instructional learning tool there could be. Great job!!!!

Your the best

[@davelambardo6464]

I went to work at a shortline about 5 years back . I have 25 years in hands on all aspects steel fabrication experience They hired me to build their fabrication skills and put together a shop tied to the mechanical department . But had to put me in exsisting department that had an opening. Which was in mechanical.. I took the job becuase of the apeal of the benefits. I designed and built spark arrestor attachment pipes for gp38 locomotives with 2 stroke engines. Which can throw some serious fire up in the air. I think I will just say it was Interesting working for the railroad..fun at times even. I made it 3.5 years found out my mechanical manager was actually trying to pass my skills off as his own. Which has zero of at all in the fabrication world . And was succsesfull enough to get a regional promotion about 6 months after I quit. He is good at stealing knowledge from many people in his career. I can't say I miss railroading

[@GrindhousePerformance]

Have to thank you for this one Justin, watched this a couple times before tackling the exhaust in my project 280z video series. Those extruded bends were AWESOME to work with.

[@zapwatt]

Thank you for saying "locking pliers" instead of using that common brand name. This is proper.

[@tobywhitaker4246]

Very good instructional video! One trick I use for drawing a straight line on pipe, is to lay a length of angle iron on it, such as 1"×1" ×1/8. It works very well. Larger pipe, I'd use larger angle. It self centers.

[@fryloc359]

I've done that too. You don't need to measure either, unless you need to mark both sides.

[@TheMrREVOlutionary]

Love watching this kind of work. I do this kind of work for a living so I take quite the appreciation in seeing others methods in figuring this stuff out. I'll be working on an x pipe configuration for my 98 grand Cherokee with a 5.2 V8. I think what's going to be best in my opinion would be a combination of the splayed x portion @ 45* spread and 45* turns to capture the end and make parallel. I tend to like this style of X-pipe for the best flow characteristics as the merge portion is done in a straight section of tube versus a radius. However, packaging is king and sometimes that don't always work. Thanks for the awesome content Justin!

[@davidsawyer1599]

Great vid. Like to learn from other trades. I am an Electrician. Months back I was installing a fence. Needed to know a measurement. My college graduate daughter was quite surprised that algebra was needed. The 3 4 5 formula in essence. "Honey everything you use the second step was math after the idea came to mind". Thanks for the education.

[@mattpolitzer2920]

Justin, You're explanations of every step in the process is easy to follow. I look forward to you fabricating a complete stainless exhaust system for my 55' Chevy Truck in the near future. Hope all is well. Matt P.

[@markburton9614]

Great video. A decent, stationary disc sander or belt sander can make up for a less than perfect bandsaw for us home hobbyists.

[@tomharrell1954]

THESE BUILDS ARE VERY DIFFICULT TO DO WITH OUT KNOWING HOW !!! YOUR FAB TECHNIQUES ARE FABULOUS!!! You are da man

[@johntenhave1]

That was a masterclass! Thank you. I would love to have seen how you welded that up, and in particular how you got right into the tightest spots. I would also like to know if you would argon back those tubes when welding the complete pipe. great work. I learnt a lot.

[@fryloc359]

This is the first video of tours I watched. I have to say, it's hard for me to find a series like this that is helpful and has a host that I like. Thanks.

[@patrickscahill254]

Thanks for sharing your expertise with those of us who want to learn more and better ourselves, fellow gear heads and fabricators who aspire to become on par with you. Keep up the good work.

You recommended stainless bros. for their products. I found out they are a 3 hour trip from me, and thry delivered in 23hrs! Also, i watched this to refresh myself on how to do all these fun combos! Thanks again for all the good vids!

[@jimstover6747]

Justin, I always wondered on fabing merges. I want to thank you for taking the time and showing us this. Thank you !

[@reneguay1347]

I made mine with a 4 inch grinder and it came out perfect

[@andrewwilson8317]

Quick tip from me that works- tack weld the pipe to the bit of box section support. Keeps job well supported and easier to get set up right off the saw. Quick clean up with grinder and ready to reuse the supports.

[@finallyitsed2191]

I have to agree with Deke Bell and his 13 year old son. It's nice to see a video of this quality without all the cussing and backlash you get on other channels. Very nice. I really like your band saw too!

[@stevesvoboda9404]

I never thought about keeping the shielding on after the heat. Good tip!

[@Limeayy]

i love these, taught me already couple of things. You have a great channel. I really can't believe you're literally letting people know how to do these nice fab work. Thanks man. I would need to learn how to tig weld.

[@Andrewlang90]

Small tip for the bandsaw for anyone. Slow the feed down, and have just enough pressure so that the slower fed blade has a chance to bite rather then skate or slide across the material. Great video Justin, quality work and content as always 😀

[@TheFabricatorSeries]

Andrew Lang Yes - it's a dead slow process. I should have mentioned these cut shots were sped up to 400-600% and they still look slow haha. Thanks for the tip!

[@Andrewlang90]

The Fabrication Series No problem Justin:) I’ll say thank you for all the tips you’ve given us 😀

[@jwright650]

What TPI (Teeth per Inch) is good for .065 wall tubing?

[@Sicktrickintuner]

jwright650 as high as you can find, i use a 10tpi, but super thin wall i might go to a 16tpi or finer.

[@jwright650]

I'm using a 10tpi and it rips the teeth right off the blade.

Austin, another quality video, chuck full of information with little easy math. Great Italian bandsaw with the motor mounted on a gear reduction gear box, plus water-based cutting fluid. I saw what appears to be a 220 volt sticker. I bought a MIG in 1984 build in Italy by the largest manufacturer in their country, still works fine today, but no TIG. Being forced to retire way early, I will own one. I know what’s like to run out of shield gas, why does it always happen on the weekend. Plus, I have seen the cost for 25/75 from $28.52 in 84 to $112.18 just in late 2019 and have every receipt in the file cabinet. Keep up the good work.

[@magnus5356]

A much faster and accurate way to get a centerline on tubes is to take two pieces of tubbing of the same diameter, clamp or tack them together at the ends, take a straightedge or similar, lay it over perpendicular to the lenght and drag it along the tubes. Flip them over and do the other side. Boom! Lines on exact center exactly opposite each other!

[@alanmony1582]

Just a tip from a US standard to metric convert. If you use a metric tape to do all your measurements the math gets much easier Instead of trying to figure out 1/3rd of 2 9/16" you just figure 1/3rd of 90mm. You can do that in your head, ez pz!!! Still a great vid on how it's done. I'll file this one away for future reference.

[@kenselleck2414]

Killer tutorial! I have subbed! I now know the best way of fitting merge pipes! I'm beginning to hate fabrication because of the grinding dust. I may have to build a downdraft grinding table like the one in the other video.

[@keithlincoln1309]

[@edgardovelazquez2446]

You been motivating for quite a while, thank you God bless you, awesome content

[@squib308]

Those look fantastic - great layout & fit-up.

[@Drunken_Hamster]

From what I understand, you could also make a y pipe by welding two angled pieces together and lobbing off the end. Still have to swage or flare it to make it round, but it should be a little faster fab wise. Probably better for making Y's that have a bigger single pipe than the two individual pipes. Which, by the way, are made for overall flow rate matching. If you have a V8 making 600HP, then you have to either have 1 pipe that can handle all of that flow, or two pipes that can handle half of that flow. 2.5 duals can do it, but a 2.5 Y into 2.5 will likely choke it. This is why you go 2.5 Y into 3.5, as the total tubular area of a single 3.5 is about the same as two 2.5 pipes.

[@TheMrREVOlutionary]

I've actually built a few Y pipes this way. Honestly it's the same whether you use a radius or a straight with some kind of angle cut. How you mentioned does make it a rather simple and time effective way but can limit packaging too. Whatever fits and has relatively good flow characteristics is king! 😎

[@3doghaus]

Great video... Just re-watched it AGAIN!

[@robertweitlauf4653]

X=Z is Y my brain hurts. Nice work. If you get tired of welding and Fab you should do voice overs or DJ.

[@stewartnagle6776]

Big thanks for including the H pipe as I need to fabricate one of those for my Jeep in a few weeks and don't see any way an X pipe is going to fit.

[@stuartcookie133]

Thanks for taking the time out to share the knowledge that took you years to master! Awesome videos.

[@erjack40]

ALWAYS wear a leather glove on the hand that's holding a part for grinding or deburring. The grinder can slide off the part and onto your hand, a deburring bit can break and the nub will cut you like a knife. Hands- on experience from a greybeard.

[@lasercutzinfo4718]

side option to bend saw is laser tube cutter, if its 5 axis its a crazy toy, we have 3 axis and it makes some things easy

[@briansmith8273]

Would you be willing to tell us what kind of badsaw you use and maybe a price range we are looking at? If not I can respect that and thank you I love the videos please keep making them.

[@briansmith8273]

I think I found the name just not the model number

[@castuyn4618]

Instead of cutting 4x 90-deg pieces and then 4x 22,5 deg again, you can immediately cut 1x 90 deg to get 2 halves, and then each half 22,5 deg in its center. As it is the same cut, the 2 halves will be exact mirrors of each other.

[@TheFabricatorSeries]

Cas Tuyn I do a lot of things different in vids for visual reference which makes it easy to follow. Cutting pieces individually is one of them.

[@marcil802]

That's real professionalism

[@erikdodson7673]

I’m sure you have answered this before, but what’s you tig set up. Like how hot are you running, how thick is the pipe, and what size tungsten are you using. And what size filler metal is that

[@kenselleck2414]

On an X pipe the elliptical area should be the same as the cross section of the pipe. The outlet pipes can have reduced diameter after the X without flow loss as long as the cross section of the outlet pipes together isn't less than 1.5 times the cross section of one of the inlet pipes. Also on a y pipe the exit should be 1.5 times the cross section of the inlet pipes. If the inlet pipes are the correct diameter merging into the same size pipe will be a restriction. You need a larger outlet because the frequency of the exhaust pulse doubles.

[@nickcautrell2514]

I'm going to be honest, I'm jealous of your bandsaw. What tooth count blade are you running on that for cutting stainless? Thanks for the video.

[@aldo9564]

Excellent video. Thank you for the mathematical precision calculations. 👍 Subbed.

[@liamjenkins82]

I was always shown to make a common line on pipe just use a straight piece of angle iron! Was always easier and quicker. Enjoyed the video though. Clear concise instructions. When tacking you use a hotter amperage than if you where actually welding. I don't get to do much tig unfortunately.

[@weiwuwai83]

Pure gold.. thank you once again . A pleasure as always...

[@johnrathbun2943]

I'm curious about how you weld in between those pipes when you can't even get the cup in there. I see you tagged them prior to full assembly, but you didn't weld them. I assume you could weld them at anytime, but to get in between those close junctions like on the X's, this is where you will have problems welding because of the cup on the tip

[@ricardosampedrobea294]

Hello @The Fabrication Series! thank you for sharing your knowledge, I would like to know if it is possible to know if I calculate custom sizing for each type of X-pipe motor together with the anti-drone J-pipe and if it is possible to calculate certain frequencies to be able to reach a desired sound as a final result. Thanks a lot.

[@matthewsweetser602]

Always excited to see new videos. This one was awesome just what I wanted to learn for some upcoming project ideas

[@WDMtea]

Does the deferent intersections of the pipes produce different sounds?

[@carlpenney901]

On the H tube I would drill the holes to the size you need. Then saddle weld the cross tube onto the H tubes.

[@willcairl3018]

You and kyle voss. The only ones I watch!!

[@mrgreenswelding2853]

Thats awesome work Justin!!

[@Handmade.Results]

So, the actual trick here, at least for the H pipe, to get the best scavenging flow is to place it where the pipes get hottest. Some thermal tape or paint from someplace like Omega Engineering on the pipe before a little run will reveal the spot.
