Exhaust Manifold Fabrication - Honda Civic ep3 K Series

[@9256steven]

Superb, I was surprised how thin the SS is and the jigs and welding are great. Well done.

[@Smffab]

Thanks

[@AlexTrull]

Really skilled job. I like how you took the guesswork out of it!

[@Smffab]

Thanks 👍🏼

[@bilaltariq7819]

Can you do more like this but show how you weld in the tight gaps between pipes like 4:26?

[@Smffab]

Plenty of stock out on the electrode and bit of a Torah angle!

[@Pablomaniac]

Great work. Enjoyed seeing it all fit together. That's a really good jig too!

[@Smffab]

Thanks 👍

[@b0bden]

Nice work, oddly therapeutic 👍🏻

[@Smffab]

Thanks 👍

[@wtfftw24]

How do you weld in between the " Y " inside sides?? That would be an interesting tutorial for who is learning 👍

[@Smffab]

Lots of electrode stick out

[@frankodemozo]

Subscribed. Looks like your from the UK 🇬🇧 and putting in work! 🤘

[@Smffab]

Thanks for the sub! Appreciate it. Yes im based in the north of England.

[@lomfmur]

I wish I could do stuff like this myself, looks amazing

[@Smffab]

Thanks. You can learn, I am self taught from KZbin videos like these.

GOOD JOB. tell me about your gas cup and who made it. I have some Pyrex one and I don't like them. To loose.

[@Smffab]

Thanks. The gas cup is a Furick cup made by Michael Furick. The one I use the most is the FUPA 12. They have some funny names, you’ll know what I mean if you go check them out.

[@Drivers.Garage]

Awesome work buddy, also wish I could get welds like yours with no back purge. Mine just contaminate to hell.

[@Smffab]

All these welds are fully back purged. Just not when tacking the parts together.

[@Drivers.Garage]

@@Smffab my mistake, just watched it back and seen the plugs. Must of missed them. Looks good fell. Awesome work.

[@Drunken_Hamster]

I wanna hear the souuunnnd! Also, if you ever decided to do a UEL, please do a 1-4 or 2-3 pair UEL instead of the traditional 1-2/3-4 pair. It can potentially sound more V8-like with the way I described as it would be mimicking an 82-86 Honda V65 Magna with a Kerker exhaust and no muffler. (I can post a link to a ~1min video if you're interested)

[@Smffab]

Sounds interesting, please share a link. You can hear the sound, link below. Enjoy 👍🏼 kzbin.infoAaEB4Ztkl5c?feature=share

I know it's a little too late but... The world's first UEL header for a K series would be an interesting project! 😁

[@Smffab]

Yes maybe 😃

[@remi009340]

@@Smffab Great work on this header by the way!

[@Smffab]

Thank you 🙏

[@CL9k24a3]

Most of them are uel but arr sold as ul. Usually there is 20mm to 40mm difference on runners from the ones I have seen and uel sucks for power.

[@michaelwr80]

Been watching your vids for a min now. great beads and excellent craftsmanship! I've been thinking of venturing into custom exhaust work myself. Question: Who is buying this? Are these just once a month fabs you do? Selling locally or do you get people from all over the country? Not trying to steal your business just trying to get some incite on how to start one. Any Info is greatly appreciated! Keep up the great work!

[@Smffab]

Thank you, I appreciate that. I don’t sell many of these but I would if I had more time as there is demand for them. Here in the Uk a lot go for the cheap Chinese made manifolds but there are quite a few good quality custom fab ones being made for those who want to pay more for better products.

[@edwomer2969]

You didn't show welding the pipes together on the last merge to the header flange. I weld the merges together after the other pipes are welded so you can get at the weld. Nice work!

[@Smffab]

No sorry didn’t show that part, but as you can imagine there is limited access so I had to use more stickout and more torch angle and still managed to get a decent weld with full penetration.

[@edwomer2969]

@@Smffab Ok but that would be a tough weld with the limited access to the side of the pipes. I make exhaust and 4 into 2 into 1 collector for it and I have jigs for each separate pipe as well as the collector. It is for a VW engine so the collector must slip onto the primaries but the collector is one piece when finished. I have found that welding each half together completely then the merge bend is the best for me but the merges are challenging with the long stick out and limited access. Still a nice job.

[@Smffab]

I think I know what your saying. It’s interesting to know other techniques and method. Thanks

[@giuseppeadamo5917]

Bellissimo lavoro, complimenti. Posso avere i parametri della saldatura utilizzati. Grazie Un saluto GA

[@Smffab]

Thank you. 43amps for tube welds. 30 CFH for argon gas flow. Which welding parameters in particular?

Looks like you made a replica of a Toda manifold. Real nice.

[@Smffab]

Thanks.

[@robertotacca2457]

Bravo ! Ma io non credo che i raccordi ai tubi tu li abbia tagliati a occhio... non hai voluto far vedere come li prepari, ok, a occhio e col pennrello puoi tagliare e costruire un tavolo in legno ;-) La piastra alla testata era in ferro o in inox anche lei ? AISI 304 o 316 ?

[@Smffab]

Didn’t want to show everything as it would probably be a very long and boring video. I’ve tried to make it short but still include as many interesting and useful parts in the video as possible. Each piece is cut using horizontal bandsaw then finer adjustments made on a belt sander to get the fit up just right. The tube and flanges are all made from 304 stainless steel.

[@mikelourey9552]

Great work! Quick question where are you sourcing your tubing? I’ve ordered from a few different places haven’t really found the right spot yet. Saw in another comment your self taught that’s incredible. Keep it up.

[@Smffab]

Thank you! I get all my tube from a company called fabco.

[@p-miner5505]

Hello, what thickness did you use for the flange and the pipes? Thanks!

[@Smffab]

Hi, the head flange is 10mm thick 304 stainless and the tube is 1.5mm thick same material as the flange

[@p-miner5505]

[@cauchemarre_]

Insane!! Are you taking commands? Can you do the same for a Fiat Punto Cabriolet 1.2 16V please (engine code is 176B9.000)

[@Drunken_Hamster]

Finding this again after seeing so many 4-2-1s with 1-3 and 2-4 (or 1-2 and 3-4 pairing) makes me wanna say "Finally, a properly designed tri-y." The only way it could be better is if you'd have stepped up the primaries at least twice, and the secondaries at least once before their respective merges.

[@Smffab]

Thanks, appreciate the feedback

[@Drunken_Hamster]

@@Smffab Actually, I might be wrong about the amount of steps on the primaries! So do your research, first, please. I DO know for sure from what I've seen and heard so far that stepped headers in general will audibly "sing" more than normal headers. If you look up the latest Maisteer video "how F1 sound is made" he explains it. But as far as power goes, my research shows conflicting information on whether you should stick with only 1 step or multiple on the primaries. 1 step is seemingly almost always good, but more than 1, IDK. Good way to get more steps (for a better sound) is to have primaries and secondaries, though, which you do.

[@Smffab]

@Drunken_Hamster thanks, that’s interesting I’ll have a look into it.

Did you have those purge blocks made ?

[@Smffab]

I just made them myself from some flat aluminium bar, then drilled the holes to bolt down and drilled the purge holes too. The materials is really very flat and no need to have these machined. They have worked well for me on many manifold builds.

[@hunterslifestyle625]

@@Smffab I like that, looks like they work well. Thanks for the reply

[@bmxlegend1997]

What size tungsten and filler do you use ?

[@Smffab]

2.4mm tungsten for everything I do and 1.2mm filler for thin wall stainless to control the puddle better

i am at the end of making same thing that looks like ugly MIG

[@Smffab]

That’s a shame

[@makantahi3731]

@@Smffab i think that tig welding is so superior in compare to mig,that it can look ugly and still can be welded good, i weld 1.6 mm thick ss316 pipe with 40A and 1 mm wire,and if i stay or go too slow, pool makes droplets inside and surface is uneven,that is why go a little faster and more heats up wire than pipe,so my weld looks like mound on pipe but it is strong and tested on car,of course purged

[@Smffab]

I use 43amps got 1.6mm stainless and dab every second so don’t hang about. Make sure you have good gas coverage and practice.
