Product Details

The Diamond Eye Manufacturing QC400-3 Quick Connect Coupler system provides a professional-grade exhaust connection solution for 4-inch exhaust systems. This kit features precision CNC-machined flanges and a high-quality V-band clamp designed for secure, leak-free connections that can be easily disconnected when needed.

Key Features:

  • Three CNC-machined flanges for precise fitment and alignment
  • One heavy-duty V-band clamp for secure, 360-degree sealing
  • 4-inch diameter design for performance exhaust systems
  • Enables quick disconnection of exhaust components for maintenance or modifications
  • Precision-machined components ensure leak-free sealing under high temperature and pressure
  • Ideal for connecting turbo downpipes, exhaust sections, or catalytic converters

This quick connect system is perfect for diesel trucks, performance vehicles, and commercial applications where regular exhaust system access is required. The V-band clamp design provides even clamping pressure around the entire circumference, eliminating the exhaust leaks common with traditional bolt-together flanges. All components are manufactured at Diamond Eye's facility using state-of-the-art CNC equipment to ensure consistent quality and precise tolerances.

Really pleased with the service I had. They had the best price I could find, and they shipped quickly. Highly satisfied

Good so far...

Nice and quick and good price.....

The price is right but shipping cost is high. I bought a transmission seal for $12.91 and shipping was $13.31. The box it shipped in was about 10 times bigger than the part itself. Reduce the box and reduce my shipping cost please ! Else than that the part was in good condition, it was packed right and shipping time was reasonable.
