Diamond Eye Manufacturing 460020 4" Perforated Packed Muffler 20" Overall Length 409 Stainless Steel

The Diamond Eye Manufacturing 460020 is a high-performance perforated packed muffler designed for custom exhaust applications requiring superior flow and sound control. Constructed from durable 409 stainless steel, this muffler delivers excellent corrosion resistance and longevity in demanding exhaust environments.

Key Specifications:

• 4-inch inlet and outlet diameter for high-flow exhaust systems
• 20-inch overall length with 14-inch body length
• 7-inch round case diameter
• Perforated core with sound-absorbing packing material
• 409 stainless steel construction for rust and corrosion resistance
• Mandrel-bent tubing for maximum exhaust flow

The perforated core design allows exhaust gases to flow through while the packing material absorbs sound waves, reducing exhaust noise without significantly restricting flow. This muffler is ideal for diesel trucks, performance vehicles, and custom exhaust fabrication projects where a balance of sound reduction and flow efficiency is required. The compact body length makes it suitable for installations with limited space while still providing effective muffling.
