Great insight to the actual thoughts of a fabricator. Pie cuts do look good, but once you explain the way they work, i see way they are so popular. Thanks Justin for the video.
My first go at a custom manifold was for a blown Blackbird engine, box of mandrels and it took me a week. I wish I knew you could buy pie cuts already cut. Brilliant post thanks
Actually super informitive makes a ton of sense thanks man that bend on jimmy's down pipe is crazy and i dont think you could have done that with a couple of 90 degree manderal bends with out cutting it in to pie cuts anyways
In all honesty I'm really torn on the way I feel about pie cut exhausts. Seems many people like the way they look but I feel they look like dryer vent hose. Thus I always grind and polish my pipes smooth. Also maybe I'm just a shitty welder but there always seems to be a off weld or an occlusion I'd just rather get rid of. By the way at like 6$ a pie, who the hell actually buys these. Make yourself a jig and you can knock off 150 pies in about 2 hours including deburing Also who needs prepolished pies. It's a joy to polish your pipe when all done and said.
Your example of when, where and why to use pie cuts makes perfect sense. What i don't understand is why some use them where they're 100% not required and a mandrel bend would suffice. IMO Pie cuts look terrible, but they certainly have their place.
100% agree, this is where being a cheap ass costs you more money at the end. Time above all else is money, and you're not charging 60 labor hours for a catback while you're cutting 20 different pie cuts off of mandrels. Spend the money, utilize pie cuts properly and send it off.
Always take a practice pass rod and all. And keep it tight. Try dipping from the side. That’s all I got. The welding just takes practice. Fit up takes years.
David floener a 250 bottle for me is around 110 I’ve heard it’s all the way down to 90 for some but backpurging doesn’t waste any gas really like he said it’s all in the welding that the gas is wasted
Thanks Jimmy Oaks for send me to this awesome fab channel!!

I was doing intercooler tubing on my coworkers supra and we needed tight bends so I had to learn how to do piecuts! I actually enjoyed using them
Awesome video. I'm not in the automotive world so it's cool to get a little insight into things like pie cuts and how/when they're used.
Good rundown
I tried out of mandrel bends but the fit up for welding was terrible
Will be doing pie cut for next tight exhaust Job👍
Asthetics. But mostly for small radius / odd bends ,you can't get from a mandrel or rotary draw
Thank you for breaking this down very simply. what are some good tools to use to measure the angles of pipes or angles under the car?

Super informative! I've always wondered what the big hype was about them. Always thought they were purely aesthetic! Thanks for posting 🤘
Aesthetically displeasing maybe
That was hella informative! nice video! and God the guys in CT are lucky to have someone that does beautiful welds like that
Have you put them on a flow bench verses mandrel bends.?
Have you ran into melting issues welding super close to your purge plugs?
What degree is easiest to cut with still sufficient flow.

Sick new Intro!!! and thank you for the wisdom bro
I have similar mask to the 1 in the background speedglass 9100 with respirator
What's your ongoing flow on your purge once it's down to zero perfect oxygen and you start welding.

How do they pull off two stroke pipes pie cuts where the pipe gets bigger diameter
Nice info. Great video, I always love the work you do!
Now i know the pros and cons will deffinitely use piecuts cheers mate!
Just saw this ... very informative.
hey bro, how it is called the song at the intro ?
Anyone try a 180 out for 2” .065 wall 6”radius
Looks killer man
I still prefer the 90° and cut them than those pointy pie cuts🤷♂️
I dont get these strange humps. Im not sure how you cut them tho
Any advice or tips for tig welding? Im working on my degree and its hard man lol
Always take a practice pass rod and all. And keep it tight. Try dipping from the side. That’s all I got. The welding just takes practice. Fit up takes years.
Tip. High frequency is your friend. Also I don't use filler rod and also sand all my pipes smooth.
With piecuts you use more argon gas right? My question is how much is argon? But I'm sure it's worth the extra $$
It uses about 5 times more than mandrel bends just because of the amount of weld and the time spent purging. Argon isn't too bad cost wise.

Also, mandrel just doesn't taste as good as pie and that's a fact
😄
Great explanation
Love this explanation, but i still prefer my answer to the haters "if you dont like it, then dont put it on your vehicle"
Spy an s30 at 9:17
👍
He defo knows about pies hahahahahah nice vid
SPOILER ALERT #2: Looking cool, also provides the opportunity to charge more money on skilled labor 😂
Personally I think they look really ugly but each to their own 👌🏼
Like dryer vent hose..amirite?
Can i be ur student lol
