Stainless Works 4 way collector 2-3/8in inlet 3-1/2in od outlet

This Stainless Works four-way collector is built from 304 stainless steel, a material chosen for its strong resistance to corrosion, which is crucial for exhaust components. It features a smooth flow taper design, helping to transition exhaust gases efficiently from the 2-3/8 inch inner diameter primary inlets to the single 3-1/2 inch outer diameter outlet. This type of collector is often used when building custom exhaust systems, allowing you to merge multiple pipes into one. It's a weld-on style part, so you'll need to be comfortable with fabrication or have a shop do the work for you.

The smooth taper is key here; it helps reduce turbulence as the exhaust gases combine, which can contribute to a more consistent flow out of the system. Because it's made from 304 stainless, you can expect it to hold up well against the heat and moisture common in exhaust applications. Stainless Works also backs this collector with a lifetime warranty, reflecting their confidence in the product's durability.
