5” Diesel Universal Muffler

Description

5″ Diesel Exhaust Muffler (Universal, T409 Stainless Steel)

This 5 inch diesel muffler is designed for high-flow trucks running full 5″ exhaust systems where sound control is needed without restricting performance. Unlike restrictive designs, this 5″ muffler keeps a straight-through core, allowing exhaust gases to pass freely while taking the edge off aggressive tone.

If you need a 5 inch muffler for diesel applications that won’t choke a large-diameter system, this unit maintains full flow while improving overall sound quality.

What This Muffler Does

A 5 inch muffler helps reduce drone and sharp exhaust note on open systems, especially on trucks running delete pipes or full aftermarket exhaust. It smooths out the tone under load and highway cruising without introducing backpressure.
