    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.

    39311 - Dynomax Bolt-On Exhaust Systems for Truck/SUV is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Great exhaust I just put this on my 05 Silverado 5.3 extended cab and it looks and sounds great. Super easy install with no screwing around to get it to line up and fit right. Has a great idle sound and gets decently loud under load. I was also impressed with the quality of hardware it came with, the two clamps seem very durable. Would defiantly reccomend this exhaust.

    Rated 5 out of 5 by from Very nice, high quality exhaust. I used this on my 2004 Silverado to replace a rusted single in dual out muffler shop exhaust the previous owner had installed. It is louder than I expected but no louder than the chambered muffler/system it replaced. it has a nice deep, mellow tone at idle but sounds pretty aggressive when you rev it. I have read other reviews about problems with the clamp for the tip but I think you just have watch how you position it. I wasn't sure if it was going to tighten enough to hold the tip in place until I repositioned the clamp and the tip so that it was compressing the back end of the clamp and it wasn't in the bend of the pipe. Once finished the tip and complete system is very solid, sounds nice and looks clean.

    Rated 5 out of 5 by from Great Exhaust! 2002 Silverado 5.3 I bought this exhaust because it was stainless steel, and 300 dollars. Other brand names were much more money for just the regular aluminized systems. This exhaust has a nice deep tone to it and sounds great. It can be really loud when you want it to. I looked at all kinds of videos online for sound comparisons but honestly the only way to know for sure is to hear it in person. If your looking to get the most for your money this muffler is it. JEGS also got this to me in two days so that was nice as well. I put this on an 02 Silverado and it sounds great. If your on the bubble with this I'd say go for it. You will not be sorry!
