Diamond Eye Muffler 3-1/2in SGL IN/SGL OUT 22in BODY 28in OVERALL OVAL

If you're looking to quiet down your diesel truck without sacrificing performance, this 3.5-inch single inlet, single outlet muffler from Diamond Eye Performance is a solid option. It's designed to handle the demands of diesel exhaust systems, helping to reduce noise while allowing gases to flow efficiently. The oval shape and 22-inch body length mean it should fit well in most factory muffler locations.

This muffler is constructed from 409 stainless steel, which is a good choice for exhaust components because it offers decent corrosion resistance, especially in the harsh environment under a vehicle. Diamond Eye uses CNC mandrel bending for their tubing, which helps maintain consistent pipe diameter through bends, ensuring smooth exhaust flow. This attention to detail in fabrication means you get a well-built part that's made to last.

When installing this muffler, you'll want to make sure you have the right clamps and potentially some exhaust sealant to ensure a leak-free connection. It's a direct replacement for your stock muffler, but always double-check the inlet and outlet sizes to confirm it matches your existing exhaust piping.
