What is a 4-way collector used for?

A 4-way collector is used in custom exhaust systems to merge four individual exhaust primary tubes into a single, larger diameter outlet pipe. This allows you to connect headers or exhaust manifolds to a single exhaust system.

What does '304 stainless steel' mean for my exhaust?

304 stainless steel is a well-known material for exhaust components because it offers good resistance to corrosion and heat. This helps your exhaust collector last longer, especially in areas exposed to moisture and road salt.

Does this collector come with any hardware?

This product is a weld-on collector and does not typically include hardware. You will need to provide your own exhaust pipe sections and have the necessary welding equipment or services to install it.

Product Details

This is a Stainless Works 4-way weld-on collector, designed to help you build a custom exhaust system. It takes four primary tubes, each with a 1-7/8 inch inner diameter, and merges them into a single 3 inch outer diameter outlet. This part is made from 304 stainless steel, which is a solid choice for exhaust components because it holds up well against rust and corrosion, even in harsh conditions.

The collector features a smooth flow taper, meaning the transition from the individual pipes to the single outlet is gradual. This design helps reduce turbulence and keeps exhaust gases flowing efficiently, which is important for performance. Since this is a weld-on part, you'll need to have welding experience or take it to a shop to have it properly installed as part of a custom exhaust build.

Stainless Works backs this collector with a lifetime warranty, and it's made right here in the USA. Keep in mind that this part is not CARB approved and cannot be shipped to California.
