Description
PLEASE NOTE: We keep most of these Tube Sections in stock, but if we do not, when you order we will order from Ace Race, and then we can pack all your VTT-FAB parts together for one shipment at one cost. This can slightly delay your order based on lead time from ACE Race. If ACE RACE shows the tube in stock, and we do not have them in stock, we can usually get them in 1-2 days.
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 (e.g.: a track car) or will see repeated high heat cycling (e.g.: 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 manifolds 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.

Dimension Disclaimer
Due to the allowed tolerances of pipe size material (spec: ASTM A403), all dimensions, including OD, ID, Wall Thickness, and Weight are approximate dimensions only. We make no guarantees that any of the dimensions provided for pipe or pipe fittings are exact measurements.
Notes
All ASTM A403 pipe fittings, except for Schedule 5 fittings, have a standard 37.5° bevel (±2.5°) on both ends. All straight lengths of pipe have a plain end with no bevel.
