The Fabricator's Choice for Building Turbo Manifolds & Merge Collectors!

The Ace Race Parts brand of Schedule 10 321 Stainless Pipe is the perfect match for our Stainless Weld Els for fabricating turbo manifolds. Our 321 Stainless Pipe offers superior corrosion resistance in high temperature applications — especially applications that will see extended periods of wide open throttle (eg: a track car) or will see repeated high heat cycling (eg: a drag car that sees significant cooling between passes). With a slight addition of Titanium to stabilize the alloy at high temperatures, 321 Stainless is an excellent choice for turbo manifolds that will be exposed to high levels of heat over a prolonged period of time.

FEATURES

  • 321 Stainless Steel
  • Seamless Construction — No Internal Weld Bead
  • Allows for a Smooth, Unobstructed Flow of Exhaust Gas
  • Durable Enough for a Wide Variety of Turbo Manifold Applications
  • Capable of Withstanding 1,600°F 
  • Manufactured to the ASTM A312 specification

304 Stainless vs 321 Stainless

One major chemical difference between 304 and 321 Stainless is the addition of Titanium (Ti) in 321 stainless to help "stabilize" the alloy and to reduce the risk of corrosion in the heat-affected zone. When 304 Stainless is heated above 1,292°F for an extended period of time it may suffer from weld decay. Weld decay is reduced by the addition of titanium, making 321 Stainless ideal for use in turbo exhaust manifolds and other exhaust products that see high levels of heat over prolonged periods of time. Although 304 Stainless is more than suitable for most turbo manifold and other exhaust applications, 321 Stainless is the superior choice for heat-related corrosion resistance.

Our 4-foot lengths of Stainless Pipe are available in sizes ranging from 1-1/4" to 2-1/2" nominal pipe size, wall thickness options including Schedule 5, Schedule 10, and Schedule 40, and in 304 Stainless and 321 Stainless. Our Pipe welds perfectly with our Stainless Weld Els and Stainless Steel Merge Collectors to create a variety of turbo manifold styles.

Cute and Comfortable
I have now purchased at least three packs of these Freetoes, so that says something; I love to wear flip flops and sandals but while walking some distance they can chafe and cause foot issues so I use the socks as a buffer, they are attractive and comfortable, especially in warmer months, and have solved the chafing issue. Highly recommend!

GOOD IDEA, BAD RESULTS
As u walk it slides up to your ankle since there's nothing to secure it between the toes, ends up looking like you have a ankle bracelet. Fabric is NOT soft and comfy. Ended up giving them all away to the my cousin that was traveling with me, she had forgotten her socks so she was desperate for anything. She had the same problem as I but because she is obese so the socks fit snug on her so took a bit longer to hike up to her ankle. Im medium built.. I purchased 2 sets so it was a waste of my hard earned money.

Do not buy these
Color: Nude, Size: Women 9-13
These are terrible. They are designed to walk in. The first day I tried them on I walked about 20 steps and they basically ripped right off my feet. I didn’t think much of it and just thought ok I won’t walk in them I’ll just wear them to bed. The second pair that came with the order I wore to bed that night and woke up with holes tore in them. Terrible product

These are form-fitting and durable. Wearing these keeps the skin moisturizer in place so it can be effective.
