Universal Exhaust Parts

Our Universal Exhaust Series features performance-focused exhaust components designed to work across a wide range of vehicles and custom builds. Every piece is fabricated in-house at Forever Fabrication in Lake Elmo, Minnesota and proudly made in the USA.

These universal parts are ideal for builders who want proven exhaust flow solutions without platform-specific limitations.

Our universal lineup includes:

  • Equalizer loop pipes
  • Universal X-pipes for improved exhaust scavenging
  • Exhaust megaphones for race-inspired flow and sound

Whether you're building a custom dual exhaust system, refining flow on a performance setup, or fabricating something completely unique — these components are built for clean integration, durability, and real-world performance.

UNIVERSAL PARTS!

Platform-Specific Performance Parts — Built in the USA

Some builds require more than universal components. Our platform-specific parts are engineered for exact fitment on dedicated engine applications, with real packaging constraints and performance goals in mind.

Every part is designed and fabricated in-house at Forever Fabrication in Lake Elmo, Minnesota — and proudly made in the USA.

Current supported platforms include:

  • GM Atlas 4200 Inline-6 (Vortec 4200)
  • GM Atlas 3500 / 3700 Inline-5

This collection features engine-specific performance components such as:

  • Turbo manifolds
  • Oil Pans
  • And with more on the way!

If you’re building on one of these engines and need parts that fit correctly, perform reliably, and are built by real fabricators — you’re in the right place.
