Product Description
DIAMOND EYE 420024 is a 24-inch section of 4.0" OD, T409 stainless straight exhaust tubing with one end expanded ("bumped") for easy slip-fit joining. It’s a universal builder’s piece for finishing or extending 4" diesel systems on popular Cummins, Duramax, and Power Stroke applications.
FAQ: WILL THIS FIT MY TRUCK?
It’s a universal 4.0" OD straight section. If your system uses 4" tubing, this pipe can be used as an extension, repair, or custom segment. Always measure your run length and confirm tubing size before ordering.
FAQ: WHAT DOES “BUMPED ON ONE END” MEAN?
One end is expanded to slip over standard 4" tubing—ideal for adding length without extra adapters, then securing with a 4" clamp.
FAQ: WHERE IS THIS USED IN DIAMOND EYE SYSTEMS?
Diamond Eye often calls this out as a straight-pipe extension in their install guides for long-bed or specific wheelbase trucks. Installers trim to length as needed and secure with a 4" clamp.
