FITMENT
- Universal Fits any vehicle/truck with a 4"/5" exhaust setup).
- Custom Exhaust Fabrication / Muffler Replacement / Repair Pipe.
DESCRIPTION
Product Overview
- When building high-performance diesel exhaust systems, modifying race pipe setups, or completing custom fabrication, having heavy-duty straight tubing is critical. Low-quality exhaust pipes can warp, corrode, and restrict exhaust flow under extreme high-temperature diesel operations.
- The Universal Straight Diesel Exhaust Pipe provides maximum airflow, exceptional durability, and custom fabrication versatility. Available in both 4" and 5" outer diameters with a 30" overall length, this mandrel-formed straight pipe offers unrestricted exhaust flow, reduced backpressure, and a solid foundation for any custom diesel exhaust build or muffler delete project.
Key Features
- High-Flow Mandrel-Formed Design: Smooth straight-through tubing minimizes exhaust restriction, lowers Exhaust Gas Temperatures, and promotes an aggressive diesel exhaust tone.
- Heavy-Duty Construction: Engineered from thick-wall steel/stainless steel to withstand extreme heat cycles, road salt, and high-vibration clamping.
- Weld or Clamp Installation: Ready for welding or clean, 100% weld-free installation using standard lap-joint or butt-joint exhaust band clamps.
- 4" & 5" Outer Diameter Options: Choose between 4.0" OD or 5.0" OD to match your exact vehicle setup, performance muffler, downpipe, or over-axle pipe.
- Versatile 30" Overall Length: Ideal length for muffler delete sections, tailpipe extensions, pipe repairs, and custom exhaust fabrication.

FAQ
Q: How do I know whether to choose the 4-inch or 5-inch option?
A: Measure the outer diameter (OD) of your current exhaust pipe using a caliper or measuring tape. If your truck has a standard 4" system, choose 4". If you have an upgraded high-flow 5" system or race pipe, select the 5" option.
Q: Is this straight pipe vehicle-specific or universal?
A: This is a universal straight pipe. As long as you select the diameter matching your vehicle's exhaust size (4" or 5"), this pipe can be cut, welded, or clamped into place for custom repairs or modifications.
Q: Can this pipe be installed using clamps, or must it be welded?
A: Both methods work great. You can weld it directly into your exhaust system for a permanent seal, or use heavy-duty lap-joint band clamps for a quick, 100% weld-free installation.
Q: Is the expanded/flared end of the pipe larger in diameter?
A: Yes. The expanded (slip-fit) end features an enlarged inner diameter (ID) designed to slide directly over a standard 4" or 5" outer diameter (OD) exhaust pipe for a seamless, tight fit before clamping or welding.
