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.

Great value: These are my go-to work from home shirt
Material Type: Recycled Polyester, Color: Blue, Size: X-Large
I’ve been pleasantly surprised by these shirts and wear them weekly for Zoom calls, since I’m still working from home these days. I figured at the price point it was worth trying them out, and now I’ve bought several in different colors. They aren’t super soft, but they are comfy and look nice. I’m 6’1” ~220 pounds, and the XL slim fit still has plenty of room. I imagine the regular cut is incredibly boxy and oversized. The difference between polyester vs recycled polyester is inconsequential. I typically buy expensive golf shirts, and these definitely aren’t as nice. They are a fraction of the cost though and a great “beater” work shirt / hang out shirt. It’s nice wearing something that looks and feels decent, but if something happens to it, you can toss and it and pick up another for the cost of a chipotle burrito.

Great price, not great quality
Material Type: Recycled Polyester, Color: Black, Size: Small
Simple, straight forward all black polo. I am a size medium woman (with some room since I don't like form-fitting) and bought a men's small. Fits perfectly for my frame. Long enough to tuck in for my part-time extra weekend job uniform. Also suitable for the golf course. A little thin, and if you hold it up to light you can sort of see through it. *Not* flowy, soft and smooth fabric like a rash guard/sun shirt - more structured than that. But it's cool and does the job for the price under $10.
