Product Details

The Stainless Works FC4250-400 is a professional-grade four-way weld-on exhaust collector designed for custom header fabrication and high-performance exhaust systems. This merge collector combines four primary tubes into a single outlet, optimizing exhaust flow for improved performance.

Key Features:

  • Premium 304 stainless steel construction for maximum corrosion resistance and durability
  • Four-way merge design with smooth flow taper for optimal exhaust scavenging
  • 2-1/2 inch inside diameter primary tube inlets (accepts four tubes)
  • 4 inch outside diameter single outlet
  • Weld-on design for permanent, secure installation
  • Precision-formed construction ensures consistent fitment
  • Proudly made in the USA
  • Backed by manufacturer's lifetime warranty

This collector is ideal for building or repairing custom headers, replacing damaged collectors, or upgrading exhaust systems on racing applications, muscle cars, street rods, and marine engines. The smooth internal taper reduces turbulence and back pressure while the stainless steel material withstands extreme temperatures and harsh environments.

Great prices

easy to navigate and checkout

I am pleased with Autoplicity. There was a miscommunication on shipment, but after a phone call, everything was handled. Looking forward to my parts coming in. Thanks guys!

you guys always beat summit, some sort of shipping discount on larger orders would be nice though. Maybe an amazon prime type thing.

Lowest price, fast shipping. Thanks!

Ordered 4 race ramps flatstoppers for winter storage of my Dodge Viper. Product prevents flat spots on auto tires that are stored more than 30 days. Order process was extremely easy, product was promptly shipped. I'll definately do business with Autoplicity in the future.

Good deals

I purchased an Airaid throttle body spacer, they has they cheapest price on the web, no one else could even compare to the prices here at Autoplicity, I will definitely order from in the future!
