    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 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 same straight-through design of the Ultro Flo Welded systems. These systems have a deep performance tone and will support up to 1,900 horsepower.

    39432 - Dynomax Bolt-On Exhaust Systems for Truck/SUV is rated 3.8 out of 5 by 5.
    Rated 5 out of 5 by from Hard to find...2008 GMC work truck I bought this three week ago and was very pleased with the fitment and sound. A little aggressive but not too much. It took me an hour to remove the OE exhaust and install the new. Very happy with my purchase!
    Date published: 2016-12-03
    Rated 5 out of 5 by from Great Fit! After searching for an exhaust for my 07 Silverado 3500HD I finally found this exhaust that fit and sounds great. My truck has the gas 6.0 Vortex engine with a single cab so trying to find an exhaust to fit was more of a challenge then I thought. After returning the first exhaust I ordered because it was wrong (from another company), JEGS had the right matching exhaust, that fit my truck! I got a lot of compliments that my truck sounds like it has an attitude now! This single sided exhaust sounds and out performs a lot of other exhaust systems I seen and heard. I paired it with an intake and a tuner...great improvement for minimal cost!

    Rated 4 out of 5 by from Good system I used this kit on my modified 03 Suburban. Of course I had to modify the brackets to fit my application. It is a nice looking system but the muffler is louder than I expected, even though the body of the muffler is large. It is supper quiet at 50mph and below, but while accelerating it is loud (I also have headers), but not obnoxious.

    Rated 4 out of 5 by from Great Sound...but After thorough internet research, I narrowed my choices down to this and the Magnaflow. I was looking for a deep throaty sound, not obnoxious. Would have gone with the Magnaflow despite being $300 more, except they didn't have the exact fitment for my cab/bedlength. The Dynomax is super easy bolt on. I did not have to cut anything to get the stock exhaust off. 2009 Silverado 2500HD 6.0 Vortec. Only hiccup I had was the clamp bolt on the exhaust tip twisted off. Jegs handled it beautifully, and I had a new clamp the next day. The sound is great on the outside, a VERY deep rumble. I think the fact that it is a 4inch diameter is the main reason, but it's low...and roars when you stomp it. 1 star deduction is for the drone at 1600-1900rpm. Otherwise, inside, it's relatively quiet. Looking back, that's one thing the Dynomax lacks that the Magnaflow has...a resonator. So now I'm considering adding one of those.

    Rated 1 out of 5 by from Horrible fit and sound I don't know if I got a lemon or if this kit is just that bad but the fitment was horrible. It ended up being about 6" off the ground and looked terrible. It was so loud in the cab that with all the windows down I couldn't even hear the exhaust outside. And the point of exhaust is to sound better and make the engine flow the exhaust gasses better but my engine worked twice as hard with this exhaust and I lost 3-4 mpg and no I wasn't driving like a teenage kid all the time. So no this is a horrible kit
