Building A Classic Mini Miglia Is Exhausting - Stainless Fabrication

[@BenRelle]

Brings back memories. "The book" when I were lad was Tuning the A-Series Engine by David Vizard. The exhaust he went for was a maniflow LCB (like yours) and an RC40 (from Minispares in London). So dutifully went off and bought both, but like yours, didn't really fit. Took a load of work to get it right, but apparently that was just what you had to do back then, and apparently still do! Your manifold is missing a clamp that goes somewhere on the gearbox bolts to hold it rigid to the engine and help with the gasket to the head from blowing.

[@rl3898]

Memories.. I have the 3C mags still from that era !

[@ronald1968]

There should be a clamp on the bottom of the downpipes that mounts to the diff output plate bolts.... this holds it firm and stops the gasket on the head blowing due to it all moving ....

[@Urchfab]

Ah, might be something that should've come with the manifold then.

My son who is 18 is in his 1st year of welding and watches your channel for inspiration.

[@Urchfab]

That's awesome, give him a high five from me!

[@strokermaverick]

Excellent, craftsmanship! Slotted exhaust hangers, were brilliant!

[@Urchfab]

Thanks! 👍

[@AlbertJanBloemendal]

You are the king! Every time I watch your videos I am amazed by the quality of your work. Thnx so much.

[@Stoney1985]

So neat, just a suggestion, add some plates to the front of the muffler and silencer to act like ramps, so the front of them cant get caught on anything, like car trailers, or if you go off track they dont dig into the ground.

[@kevinhamling1963]

G'day, I always appreciate being able to watch you weld. So, thanks for sharing. ✌️ Peace from Melbourne Australia.

[@Urchfab]

I appreciate you following along! Cheers

[@terencepickles3771]

Excellent work as always fantastic to watch 👌

[@paultierney6038]

Really nice job 👌

[@paulkemp4559]

“One of the benefits of working with metal is that you can stick it back together when you cock it up” PRICELESS 🤣

[@adsminibuild5791]

Looking really good

[@BenRelle]

10:16 - "fits really well" - might even say 'like a glove' :)

[@peterhills5594]

Just be careful that you don't fail the 40mm ride height check with that box in the centre tunnel at the ride height we run Migs/Libres. There's a teason the box is at the back and the pipe is tucked toght up into tunnel

[@Urchfab]

I will check mate but I'm pretty sure there's way more than 40mm clearance. Cheers

[@anonintellect9882]

Exhaust exit looks sweet, I like it anyway 👍 ps great giveaway idea! Very nice!

[@mrb1864]

Best I buy some tickets while the ticket offer running and try get myself a tig machine and some useful tuition to get better/easier initial results . Fabco link looks useful, ability order some bends with custom tail lengths can be useful as can expanding ends ... Be nice hear the mini exhaust, keep up the good work ...

[@koolkar55]

Very Cool Matty. Can't wait sometimes for an update Mate. As always, love ya work. Billy J...... Queensland, Australia.

[@Urchfab]

Thanks Billy, always good to see you chime in! Cheers

[@PaulinesPastimes]

Gorgeous job. Fit a fatter tail pipe 😊👍

[@fatman3785]

Worth a punt on the competition!

[@Urchfab]

Good luck mate

As always nice, clean solid work, my man.

Brilliant video Matt!

Très beau travail comme d’habitude,bravo

Looks good!

Thanks mate

Beautiful.

Teaching myself TIG at the moment. The biggest learning curve is remembering to NOT put your filler rod on the table EVERY DAMN TIME

[@4speed3pedals]

Here in the states, muffler manufacturers can get you ticked. Only one maker posts any flow data that is easily found. Sound level is another issue but for high speed performance, the ability to make a muffler invisible to the engine is important. I have searched many videos online hoping to get a better understanding of the sound produced but even that can be misleading. David Vizard talks about mufflers in one of his publications and has a diagram of one that is invisible to the engine as far as restriction, allowing the headers to to their intended job and not cause reversion in the intake manifold. I am seriously thinking about making 2 as per diagram to see what happens and if it works, then make them from stainless steel. Just because everyone uses one brand over the other may be more of a sound and seat of the pants feel vs actual testing with data to prove it out.

[@dennisvaneck9406]

And when the exhaust slides of (not if..) you may want to catch it with something like a loop, perhaps some earth straps.

[@davidwoods6821]

welding next to acetone container makes me nervous, had a bit of a mishap myself though that was with MIG so lots of sparks!

[@Urchfab]

Funny you should say that. In my classes I make a point of taking about not having flammable items in the welding area. Do as I say not as I do!

[@ferjarvis2841]

Nice video i enjoyed watching this 👌

[@Urchfab]

Glad to hear it. Cheers

[@albegt98]

good job man 👍💪

Nice one 👍

Nice to see you buddy 👍 mini is coming along... LAG

Getting there! Thanks 👍

As you said, jobza gudden

Turned out mint, there's a reason I'm not a carpenter id get sacked on the first day ha ha

[@richardbrowne3641]

Question: Did you think of using a stainless steel braded flex pipe on the collector pipe from the header to exauhst pipe? Just curious, Urchman. "CHEERS!"

[@Urchfab]

I thought about it, but the engine is pretty much solid mounted so not sure its necessary. Time will tell. Cheers

[@richardbrowne3641]

@@Urchfab 👌

[@demonhighwayman9403]

I'm no expert but with the exhaust bolted so securely, will engine vibration not cause the exhaust to break ? I'm just curious, not trying to be hateful !

[@sjv6598]

It’s not rigid mounted. They are on exhaust rubber bobbins that allows movement.

[@demonhighwayman9403]

@@sjv6598 I did see that but thought they looked really solid.

[@jzab]

I’d be more worried by the expansion of the pipe due to temperature. A 3 metre stainless pipe gets about 19 mm longer with a 400 degrees C rise. It’s about 24 mm longer if the rise is 500 degrees C. That might shear those mounts off.

[@deangaryjames]

Never tried tig, looks so neat and less dramatic than my birdcrap mig and hit n miss stick welder!

[@BillyBob-uc9zp]

Nice job Mr 😎 P.s You still gunna race it?

[@michaelhansen6481]

👍

[@MgBaggg]

But new exhaust sound how? :(

[@paulwhite7475]

Every mini exhaust I've ever built i always angle the back box and bring it out the left side . I've always thought center exit exhausts just looks like the car has an arsehole

[@Urchfab]

But everyone should have a arsehole.

[@Yonko1990]

[@stephenwhite5057]

Those thimbles will last much longer in compression.

[@Urchfab]

Thanks Billy, always good to see you chime in. Cheers

[@thatdudeinorange5269]

After all these years of people racing Mini's you'd think someone could make a well fitting exhaustmanifold. But nah, doesnt seem like it will happen.

[@leighrees1649]

Dude I cannot find anyone local who will even touch my car to sort the exhaust out I went to long life exhaust and told them it needs pie cuts and they were like no that takes to long but we can sell you a new exhaust I was like thanks but no and left

[@Urchfab]

If your willing to pay the price there's companies that will do it. It's time consuming work so generally costs a fortune, most the time an off the shelf part is gonna be much cheaper.
