The Ace Race Parts line of 321 Stainless Steel Pipe is the fabricator's choice for high temperature turbo manifolds. Trusted by the most recognizable names in the manifold fabrication business, 321 Stainless can withstand the extreme temperature fluctuations of high horsepower drag and track cars and exposure to operating temperatures as high as 1,652°F.

In applications where the manifold is exposed to long-term high temperature exposure (e.g., a track car that spends an extended period of time at WOT), or exposed to large temperature fluctuations (e.g., a drag car that experiences maximum temperatures and then cools to near ambient temperatures multiple times per day), 321 Stainless is the superior option when compared to 304 Stainless.

SIZING NOTE: All of our pipe size fittings are referenced by a nominal size, not an exact size. Nominal Pipe Size material sizing does not imply the actual OD or ID of the item. Pipe size material is only compatible with other pipe size material and will not work with mandrel bends, tubing, or other tube size items. If an item on our website references a size with a decimal (eg: 1.500") the product is referencing tube size material. If the size is referenced with a fractional size or without a decimal (eg: 1-1/2") the product is referencing pipe size material. Please reference the data on each product page to ensure that the correct size is ordered.
