Product Description
DIAMOND EYE 405040 is a universal 5.0" aluminized straight section (40" overall) with a bumped/expanded end for easy slip-fit installation. Use it to extend, repair, or fabricate 5" diesel systems while maintaining smooth flow and durable, corrosion-resistant performance.
FAQ: WHAT DOES “BUMPED ON ONE END” MEAN?
One end is expanded to 5" ID so it slips over standard 5" OD tube. The other end is 5" OD to slip into an expanded section or clamp. This makes mid-pipe extensions and repairs straightforward.
FAQ: IS THIS PIPE MODEL-SPECIFIC?
No—this is a universal 5" straight section for custom diesel exhaust work on Ford Power Stroke, GM Duramax, Ram Cummins, medium-duty, and off-road builds that use 5" tubing.
FAQ: WHAT CLAMP SHOULD I USE?
For slip joints, a 5" lap-joint band clamp or a 5" U-bolt saddle clamp both work. See the Diamond Eye clamp options linked below.
