Dynomax Ultra-Flo Welded Mufflers

Ultra-Flo Welded Mufflers feature stainless steel construction with a straight-through design and sound-deadening CRF (continuous roving fiberglass) technology. Heat-resistant to 1500°, CRF absorbs interior resonance yet maintains a deep exhaust note. Mufflers support up to 2000 HP and are proven to flow up to 2200 cfm. Additionally, Ultra-Flo X Mufflers have stainless steel mesh and internal pass tubes with perforations to further maximize sound absorption. Direct replacement mufflers also available.
