Product Description
DIAMOND EYE 510205 is a universal 4.0" aluminized steel muffler replacement pipe with a 30" body. It replaces a restrictive muffler section in a 4" exhaust to restore straight-through flow and sharpen exhaust tone for performance builds.
FAQ: WILL THIS FIT MY TRUCK?
This is a universal 4.0" x 30" straight section intended to replace a 4" muffler in aftermarket systems. If your system uses 4" tubing and has space for a 30" body, it will typically work. Always measure your existing system before ordering.
FAQ: WHAT MATERIAL IS IT?
Aluminized steel for durability and corrosion resistance at a value price. For stainless, see the Diamond Eye stainless 30" option linked below.
FAQ: DO I NEED ANYTHING ELSE TO INSTALL IT?
You may reuse your existing band clamps. If you need new hardware, consider 4" clamps from Diamond Eye (linked below). Ensure proper alignment and torque for a leak-free seal.
