    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.

    17537 - Dynomax Ultra-Flo Welded Mufflers is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from I good muffler overall This muffler is a lot different than the stock muffler and I needed to have it installed at a muffler shop. It wasn't a big deal I guess I was expecting a muffler that I could unbolt the old and bolt the new in. Aside from that I'm happy with it. Definately louder than stock which I don't mind but never too loud IMO.
