This is my second system, Dynomax has upgraded the clamps and muffler since my original purchase. The upgraded stainless slip over style clamps are much easier to use and install. They were a much needed improvement. The standard style clamps are what contributed to my first pipe to rust out.It created a pinch point and a great place for road salt to just sit and cling to. My first system was quieter and muffler was slightly different. The new muffler has deeper sound, and nicer polished looking finish. Overall the improvements Dynomax made are functional, eased installation and provide performance. My stock muffler and tailpipe rotted out at 52k, the 1st Dynomax system lasted 85k. Hopefully this one will out last both. This is on my daily driver, New England winters/salt. Passes emissions testing, sounds good, nice look with SS tip. Nice upgrade over stock/OEM replacement. All needed brackets, bolts, donut gasket are included. Bottom line, hard to beat for the cost and what you get, proudly made in USA.

Product was shipped quickly and arrived on time.
The exhaust system was designed as a direct replacement and as a result was easy to install. The stainless steel construction and polished stainless steel muffler looks great. However I was disappointed with the final results. I realize my vehicle is only a 4.0 6 cyl Ford Ranger but I was hoping for a better sound and performance. My truck now just sounds like a 6 cyl with a noisy muffler. I will probably end up replacing it again with another brand.

      Comments about Dynomax Syst-Ultra Flo Weld:

      Perfect fit on my 2003 Ranger Super Cab. Its a nice mellow sound , not at all loud , and no more hissing like the factory system.
      Only reason its not 5 stars is that it dosent include 2 new bolts for the the front pipe , which my old ones were rusted badly.
      It's not much louder then stock , just mellow :)
      All stainless steel, including the muffler

      Comments about Dynomax Syst-Ultra Flo Weld:

      This system seems good so far. It is a little louder but I can not hear it with windows up so it is not to loud. The truck felt slow with the old exhaust system that was restrictive. This system definitely improved power. Looks good. One clamp didn't fit so I had to buy a regular exhaust clamp, no big deal. lets see how long it lasts.

        I don't have anything bad to say about this product. The install was easy and everything fit together the way it was supposed to and appears to be good quality. However I would recommend buying a 2 1/2" metal swivel hanger to hang the tail pipe if you have an older vehile because your original hanger is most likely done for.

          Sounds better the more it's driven. Was easier to piece together than to follow instructions. As for the price, 1/2 of what most cost, sounds as good if not better than most.

          Hardest part was removing stock system from hangers... Good, typical dynomax sound for a bargain price. Notice low end power instantly. A tad of drone at certain rpm's under certain load conditions. Not bad though. Quiet idle, quiet on freeway, just enough to let you know it's there.

          It was louder than what I wanted. I'm not a truck wammy and don't need to wake up the neighborhood when I start my truck. Wish it wasn't so loud.
          but should last for 8-10 years. Great price with
          ADvance!
