Product Details

This is a Stainless Works four-way exhaust collector, designed to merge four exhaust pipes into one. It features 2-1/4 inch inner diameter inlets and a 4 inch outer diameter outlet, making it a solid choice for custom exhaust builds where you need to consolidate multiple pipes into a single exit point. The smooth flow taper helps reduce exhaust restriction as the gases merge.

Constructed from 304 stainless steel, this collector is well-built to resist corrosion, which is important for any exhaust component exposed to the elements. The slip-fit design means the inlet pipes slide into the collector, allowing for easier welding during installation. This part is proudly made in the USA and comes with a lifetime warranty from Stainless Works.
