| dynomax Ultra Flo Ss muffler View
The Ultra Flo SS muffler features a T-304 polished stainless steel case with a straight-through 409 stainless steel internal design. The outcome of the Ultra Flo SS design is a true performance tone at a moderate sound level. Continuous roving fiberglass technology minimizes resonation.
The Ultra Flo Welded utilizes a heavy-gauge, hand-welded case with straight-through internal routing for an aggressive performance tone and sound level. The Ultra Flo X-muffler uses an encased 3.0-in. perforated tube X-pipe surrounded by CRF for minimal resonation. With a carefully engineered crossover section that ensures maximum flow, the Ultra Flo X-muffler delivers the natural balance and flow characteristics of an X-pipe configuration within the straight-through design of an Ultra Flo muffler.
