Product Description
DIAMOND EYE 420048 is a universal 4.0" OD straight section in T409 stainless steel, 48.0" long, with one end expanded (bumped) for easy slip-fit connections. It’s ideal for custom exhaust builds, repairs, or extending 4" systems on Dodge, GM, and Ford diesel platforms.
FAQ: WILL THIS FIT MY TRUCK?
Yes—this is a universal 4" outside-diameter straight tube. If your system uses 4" tubing, it can be cut and clamped or welded in place. Always measure your existing tubing and joint style before ordering.
FAQ: WHAT DOES "BUMPED ON ONE END" MEAN?
The expanded end slips over standard 4" tubing for quicker mock-up and assembly, reducing the need for separate adapters.
FAQ: STAINLESS VS. ALUMINIZED—WHICH SHOULD I CHOOSE?
T409 stainless offers improved corrosion resistance versus aluminized, making it a smart choice for rust-prone regions and year-round daily drivers.
