    Great Performance, Great Sound, Great Price!

    All Dynomax systems are true bolt-ons, designed to attach directly to existing mounting points for an easy installation. They follow OE routing and feature top-of-the-line performance mufflers, mandrel-bent pipes for smooth exhaust flow, and all-aluminized materials for longevity and better appearance.

    Dynomax SS Exhaust Systems are made completely from stainless steel. Each kit is dyno proven to make more horsepower & torque. Free flowing Ultra Flo Welded mufflers and mandrel bent tubing increase performance & fuel efficiency.

    Dynomax Super Turbo systems feature Dynomax's flow director technology with large internal flow tubes which eliminate turbulence and improve exhaust flow while reducing backpressure. The fiberglass matting gives the Super Turbo a mellow performance tone.

    Dynomax Ultra Flo Welded systems feature a stainless 100% welded muffler that uses a straight-through design that ensures unrestricted air flow and reduces back pressure. These systems have a deep performance tone.

    Dynomax Ultra Flo systems feature a seamed, un-welded, 100% polished stainless muffler that uses the same straight-through design of the Ultra Flo Welded systems. These systems have a deep performance tone and will support up to 1,900 horsepower.

    Features:

    • Assorted Styles and SoundTones

    39450 is rated 3.5 out of 5 by 4.
    Rated 5 out of 5 by from Great fit I'm so happy with this kit looks good sounds good and fit perfect on factory hangers!
    Date published: 2019-03-14
    Rated 4 out of 5 by from Hard to beat for the price. Installed about a week ago and very happy with the sound. No highway drone, nice tone accelerating. Install was not to bad, took some time to get lined up but all hangers were in correct location. Only issue was the rear add on hangers. They won't set flush against the frame without a spacer like a washer to space out so they are flat and level. All in all for the money I am very happy with the system. If I would have spent over $600.00 then I would have complained but for the money a good buy for sure!

    Rated 3 out of 5 by from dynomax exhaust Bolted together fairly easy. The exhaust crosses over and hangs down behind rear axle housing and is an awful sight. It is made of the usual low grade magnetic stainless so it will not last. Very mellow if at all noticable exhaust note.
    Date published: 2015-08-25
    Rated 2 out of 5 by from Does not bolt right up to My 2009 F150 crew long I do like the overall quality of the system but it is not a direct bolt on system for my 2009. Your listing shows it works for 2004-2009 but the instructions say 2004-2008 Perhaps because my truck is a crew cab with the 6.5 box but it was a bit disappointing. And when I talked with dynomax they told me my exhaust pipe on my truck must not be factory blah blah.
