Product Details

If you're building a custom exhaust system or modifying your existing one, a good collector is key to smooth exhaust flow. This 4-way collector from Stainless Works helps merge your primary exhaust tubes into a single outlet, designed to keep exhaust gases moving efficiently.

It's made from 304 stainless steel, which is a solid choice for exhaust components because it holds up well against corrosion and heat. The design features a smooth flow taper, meaning it gradually merges the exhaust gases rather than creating abrupt transitions that can cause turbulence. This collector has 2-1/8 inch inner diameter inlets for your primary pipes and a 4 inch outer diameter outlet, intended to slip-fit onto your next exhaust section.

This is a weld-on component, so you'll need to be comfortable with welding to install it. Stainless Works backs this collector with a lifetime warranty, and it's made right here in the USA.
